What level of disk shock protection is there in Portege R830

Folks,
I work in an area where there are lots of people who carry their Portege Laptops (mostly R830's) around while they're still on - mainly while they're moving from desks to meeting rooms etc, and often carrying them on an angle. I feel a bit silly because I insist on putting mine to sleep before I move it.
What level of disk shock protection is there in these laptops? Am I being paranoid or is everyone else inviting disaster?
Thanks,
Yokki

Hi
First of all its not really good for the HDD if the notebook would be moved while the HDD is in use in such case the HDD read/write head would be affected while carrying along but there is a software called Toshiba HDD protection which use an sensor built in the notebook. the HDD protection detects the vibrations and shocks and automatically moves the HDD head in a safe position to reduce the risk of damage caused by head to disk contact.
Here more details:

Disk shock protection for Dell laptop

Welcome Archers!
I have laptop Dell Studio 1558. I want to turn disk shock protection.
I read the wiki
https://wiki.archlinux.org/index.php/La … protection
and
https://wiki.archlinux.org/index.php/HDAPS
but I do not know what method is good for Dell.

I don't think any of those will work for you, Becoz both of them are clearly not targeting dell.
It wont hurt to try, but how will you know that its proctecting your Disk?

Hard disk shock protection

I want to upgrade my internal 80GB Toshiba HDD to a 160GB Hitachi drive.
I have read that the Macbook HDD shock protection system is on the motherboard
and that any drive will be protected. Does anyone know for sure if this is true ?
Thanks, Tom

Thanks, Kappy
On the old Toshiba drive there was a 3 or 4 pin connector that isn't present
on the Hitachi, and I thought this had something to do with the HDSP.

What is the best virus protection for a Mac?

What is the best virus protection for a Mac?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. Beyond XProtect, Gatekeeper, and MRT, there’s no evidence of any benefit from other automated protection against malware. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style "virus" affecting OS X. Merely loading a page with malicious Java content could be harmful. Fortunately, Java on the Web is mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it, when necessary, only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
9. The greatest harm done by security software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
10. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.

What level of access a DBA should have on production Environment

We are in the process of auditing
I want to know what level of acccess a DBA has on a production server..How about the Backups ONLINE/EXport backup? Which account should be used for those purposes...
Can i DBA login as SYSTEM or SYS user? or he should have separate account to do all the activities..
I am more on protecting the data from unauthorized user..Any standards followed for that

Hi Maran,
What level of access a DBA should have on production Environment
root
However, there have been cases of dishonest DBA's and SA, manipulating data for profit and stealing data:
http://www.dba-oracle.com/art_lumigent_whitepaper.htm
Kevin Mitnick, the noted computer felon likes to show how security breeches are commonly the result of employee errors. In his book “The Art of Deception”, Mitnick talks about his techniques to get trusting employees to disclose confidential information and privileged passwords. In one case Mitnick was able to secure a privileged password using the name Lemonjello, and then bragged about the naïve employee who handed-over a system password to someone called “Lemon Jell-O”. In this case the IT staff was never able to ascertain the root cause of the breech because their mechanism for the dissemination and auditing of secure information was inadequate.
Today, there are ways to seregate the audit trails, giving the DBA what they need to do their job, while not giving them the keys to the kingdom.
Hope this helps . . .

Any specific suggestions/links, please?
TIA

Such a high-esteem for fellow human beings - and
programmers...
You know, there are some good decent nice people
behind those names?
You'd be amazed at how much testing goes into a product.
[SNIP]
g'day Hatter...
Yes, I know there are some good decent nice people behind those names..fellow human beings - and fellow programmers (so yes, I do know...) In previous incarnations I have 'thunk up' and developed, Marketed & supported considerably more complex Apps & systems myself - I even know some of the people you mention personally - and they are usually decent Blokes/women but normally, it isn't the programmers who make the decisions on pricing/features/support/performance/upgrade costs & cycles etc...
My only error was, I agree, the phrase 'without exception' - but (mainly) only because I haven't bought/tested & used all of them very very recently. So I offer my apologies to those to whom my remarks should not apply (long, late night/early morning frustration...)
However, I also offer a few simple pertinent examples:
One 'top name' Utility company had a 'save your Mac HD' product on the market for some time that was almost guaranteed to TRASH it irretrievably but did NOT say so - nor did they help or compensate those they harmed.
Several are selling what amount to simple, pretty, GUI shells for 'free' or OS-included command line tools - no more, no less but do NOT say so and are asking good money for the 'software'.
Many are asking ridiculous prices for "regular upgrades" so you can keep their tool current with your Mac OS - one wants US$100/year for it, another, $15 per u/g, others, US$25 or $40 per u/g; one asks 'only' $10 - and these 'upgrades' are happening 3,4,5,6 times per year and are necessary for the Marketing company to keep their product Saleable to new purchasers and new Macs (as well as for important Bug Fixes - and only co-incidentally to keep it performing with your current Mac and OS - which is what you paid them for in the first place).
I won't pay for a product 3, 6 or 9 times and I won't advise my clients to: It's not unreasonable for a person to expect a 'sensible lifetime/currency' of Product X for Computer Y - say 3 years (e.g. AppleCare). I wouldn't object to paying for an "upgrade" at that point - IF it's worth the money.
Software is Waaay too expensive in many cases and is simply inviting 'piracy' - from people who have already PAID for the product: sadly, they are killing their own Gooses.
Seriously, one product costs ca. US$100 to Buy in the first place
To keep it actually working for you costs about the same again Per Year - a 3 year 'sensible lifetime' or 'currency' cost of US$300 or $400! [That'll buy a lot of 'bare drives' to put in a handy Firewire case for automatic backups in Background, differential backups etc. and other simple practices which render this product type largely unnecessary ].
For what? A relatively simple set of utilities which would actually cost the company involved less than $5 total each - over 3 years - to make available to existing ( or 'current') owners. [Applecare 'complete' Hardware and Software warranty & support on a US$2000 iMac - which includes Tech Tools Pro Deluxe or somesuch costs about US$165 for 3 years. Total.]
Having designed, developed, Marketed, supported & maintained more complex Applications to/for a sizeable user-base (in US terms) over multiple complete Series of Product 'life-cycles' - regular Updates and all, I think I know where the pirates are.
These practices have been rampant in the MSWindows™ market for a longtime. It's a real shame to see it in the Mac world.
I have all the esteem in the world for those fellow human beings who deserve such - and programmers who are 'good decent nice people'.
I have none to spare for monopolists, 'exploitationists' or any of those who take unfair/unreasonable advantage of their fellow human beings - AND of programmers who are 'good decent nice people' (like, say, ME... .
In any event, as I said: they are "killing their Gooses": I know of at least 6 software companies which went this route a while back. All are dead or dying.
Thank you for your help - and the opportunity to apologise for 'mis-speaking'.

How to find Latch and what actions need to be taken when there is a latch

Hi
Can you please tell me how to find Latch and what actions need to be taken when there is a latch?
Thanks
Regards,
RJ.

1. What is a latch?
Latches are low level serialization mechanisms used to protect shared
data structures in the SGA. The implementation of latches is operating
system dependent, particularly in regard to whether a process will wait
for a latch and for how long.
A latch is a type of a lock that can be very quickly acquired and freed.
Latches are typically used to prevent more than one process from
executing the same piece of code at a given time. Associated with each
latch is a cleanup procedure that will be called if a process dies while
holding the latch. Latches have an associated level that is used to
prevent deadlocks. Once a process acquires a latch at a certain level it
cannot subsequently acquire a latch at a level that is equal to or less
than that level (unless it acquires it nowait).
2. Latches vs Enqueues
Enqueues are another type of locking mechanism used in Oracle.
An enqueue is a more sophisticated mechanism which permits several concurrent
processes to have varying degree of sharing of "known" resources. Any object
which can be concurrently used, can be protected with enqueues. A good example
is of locks on tables. We allow varying levels of sharing on tables e.g.
two processes can lock a table in share mode or in share update mode etc.
One difference is that the enqueue is obtained using an OS specific
locking mechanism. An enqueue allows the user to store a value in the lock,
i.e the mode in which we are requesting it. The OS lock manager keeps track
of the resources locked. If a process cannot be granted the lock because it
is incompatible with the mode requested and the lock is requested with wait,
the OS puts the requesting process on a wait queue which is serviced in FIFO.
Another difference between latches and enqueues is that
in latches there is no ordered queue of waiters like in enqueues. Latch
waiters may either use timers to wakeup and retry or spin (only in
multiprocessors). Since all waiters are concurrently retrying (depending on
the scheduler), anyone might get the latch and conceivably the first one to
try might be the last one to get.
3. When do we need to obtain a latch?
A process acquires a latch when working with a structure in the SGA
(System Global Area). It continues to hold the latch for the period
of time it works with the structure. The latch is dropped when the
process is finished with the structure. Each latch protects a different
set of data, identified by the name of the latch.
Oracle uses atomic instructions like "test and set" for operating on latches.
Processes waiting to execute a part of code for which a latch has
already been obtained by some other process will wait until the
latch is released. Examples are redo allocation latches, copy
latches, archive control latch etc. The basic idea is to block concurrent
access to shared data structures. Since the instructions to
set and free latches are atomic, the OS guarantees that only one process gets
it. Since it is only one instruction, it is quite fast. Latches are held
for short periods of time and provide a mechanism for cleanup in case
a holder dies abnormally while holding it. This cleaning is done using
the services of PMON.
4. Latches request modes?
Latches request can be made in two modes: "willing-to-wait" or "no wait". Normally,
latches will be requested in "willing-to-wait" mode. A request in "willing-to-wait" mode
will loop, wait, and request again until the latch is obtained. In "no wait" mode the process
request the latch. If one is not available, instead of waiting, another one is requested. Only
when all fail does the server process have to wait.
Examples of "willing-to-wait" latches are: shared pool and library cache latches
A example of "no wait" latches is the redo copy latch.
5. What causes latch contention?
If a required latch is busy, the process requesting it spins, tries again
and if still not available, spins again. The loop is repeated up to a maximum
number of times determined by the initialization parameter SPINCOUNT.
If after this entire loop, the latch is still not available, the process must yield
the CPU and go to sleep. Initially is sleeps for one centisecond. This time is
doubled in every subsequent sleep.
This causes a slowdown to occur and results in additional CPU usage,
until a latch is available. The CPU usage is a consequence of the
"spinning" of the process. "Spinning" means that the process continues to
look for the availability of the latch after certain intervals of time,
during which it sleeps.
6. How to identify contention for internal latches?
Relevant data dictionary views to query
V$LATCH
V$LATCHHOLDER
V$LATCHNAME
Each row in the V$LATCH table contains statistics for a different type
of latch. The columns of the table reflect activity for different types
of latch requests. The distinction between these types of requests is
whether the requesting process continues to request a latch if it
is unavailable:
willing-to-wait If the latch requested with a willing-to-wait
request is not available, the requesting process
waits a short time and requests the latch again.
The process continues waiting and requesting until
the latch is available.
no wait If the latch requested with an immediate request is
not available, the requesting process does not
wait, but continues processing.
V$LATCHNAME key information:
GETS Number of successful willing-to-wait requests for
a latch.
MISSES Number of times an initial willing-to-wait request
was unsuccessful.
SLEEPS Number of times a process waited a requested a latch
after an initial wiling-to-wait request.
IMMEDIATE_GETS Number of successful immediate requests for each latch.
IMMEDIATE_MISSES Number of unsuccessful immediate requests for each latch.
Calculating latch hit ratio
To get the Hit ratio for latches apply the following formula:
"willing-to-wait" Hit Ratio=(GETS-MISSES)/GETS
"no wait" Hit Ratio=(IMMEDIATE_GETS-IMMEDIATE_MISSES)/IMMEDIATE_GETS
This number should be close to 1. If not, tune according to the latch name
7. Useful SQL scripts to get latch information
** Display System-wide latch statistics.
column name format A32 truncate heading "LATCH NAME"
column pid heading "HOLDER PID"
select c.name,a.addr,a.gets,a.misses,a.sleeps,
a.immediate_gets,a.immediate_misses,b.pid
from v$latch a, v$latchholder b, v$latchname c
where a.addr = b.laddr(+)
and a.latch# = c.latch#
order by a.latch#;
** Given a latch address, find out the latch name.
column name format a64 heading 'Name'
select a.name from v$latchname a, v$latch b
where b.addr = '&addr'
and b.latch#=a.latch#;
** Display latch statistics by latch name.
column name format a32 heading 'LATCH NAME'
column pid heading 'HOLDER PID'
select c.name,a.addr,a.gets,a.misses,a.sleeps,
a.immediate_gets,a.immediate_misses,b.pid
from v$latch a, v$latchholder b, v$latchname c
where a.addr = b.laddr(+) and a.latch# = c.latch#
and c.name like '&latch_name%' order by a.latch#;
8. List of all the latches
Oracle versions might differ in the latch# assigned to the existing latches.
The following query will help you to identify all latches and the number assigned.
column name format a40 heading 'LATCH NAME'
select latch#, name from v$latchname;

What is a disk? i am told its full

what is a DISK? I am told its full

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

I want to set up the Time Machine and I would love to use the Time Capsule but since I already have a wireless router I need suggestions on what other external disks Apple could recommend to use with the Time Machine and how to configure that disk

I want to set up the Time Machine and I would love to use the Time
Capsule but since I already have a wireless router I need suggestions on
what other
external disks Apple could recommend to use with the Time Machine and
how to configure that disk.
A complication that I need to resolve is the fact that I am using Vmware
Fusion to be able to use Windows on my Mac. Now it seems that Time
Machine is not backing up my files
on that virtual Windows without additional configuration and my question
is whether you can advise me here or whether this is only a matter for
the Fusion virtual machine.

If you want to use Time Capsule you can.. you simply bridge it and plug it into the existing router.. wireless can be either turned off or used to reinforce the existing wireless.. eg use 5ghz in the TC which is much faster than your 2.4ghz.
You can also use a NAS.. many brands available but the top brands are synology, qnap and netgear readynas series. These will all do Time Machine backups although how well always depends on Apple sticking to a standard. There are cheaper ones.. I bought a single disk zyxel which was rebadged and sold through my local supermarket. It actually works very well for TM at least on Snow Leopard. Major changes were made in Lion and again ML so do not instantly think it will work on later versions. I haven't tried it yet with those versions.
Any external drive can be plugged into the mac. Use the one with the fastest connection or cheapest price according to your budget. USB2 drives are cheap and plentiful. But no where near as fast as USB3 or FW800. So just pick whichever suits the ports on your Mac. Interesting Apple finally moved to USB3 on their latest computers.
TM should exclude the VM partition file.. it is useless backing it up from Mac OS side.. and will slow TM as it needs to backup that partition everyday for no purpose.. TM cannot see the files inside it to backup just the changes.
You need to backup windows from windows. Use MSbackup to external drive.. if you have pro or ultimate versions you can backup to network drive. But MSbackup is a dog.. at least until the latest version it cannot restore the partition without first loading windows. There are about a zillion backup software versions for windows.. look up reviews and buy one which works for you. I use a free one Macrium Reflect which does full disk backups and is easy to restore.. to do incremental backups though you have to pay for it.

I have always heard that Macs are less likely to get infected with a virus. My computer has been running much slower since I installed Maverick. Just not sure what the problem might be. Is there a way for me to run a diagnosis?

Some have found relief just by reinstalling, but it is more than likely incompatible third-party applications that slow it down.
You will have to investigate to see what it is.
Open Activity Monitor and see if anything is using a lot of CPU% or Memory. If they are, check to see if there is an update for them.
Another place to look is the Console. See if anything is logging repeating messages with throttling and/or respawn in the All Messages list.
Sometimes it is not that easy to root out the problems, but if you have anything that purported to clean, protect, optimize, maintain, or flush your system, then that is likely the cause.

Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
First, Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
In the Memory tab, are there a lot of Pageouts?

What is a disk image??

Hello,
I've just backed up my Mac, onto an external hard disk. I've now begun to think that I should make it secure, so if it ever fell into the wrong hands they can't access it without a password.
I understand that I have to create a 'Disk Image'. But what is a Disk Image? Is it simply a folder with my backup in, which is protected by a password?
I've opened Disk Utility, gone to File > New > Disk Image from Folder > selected my backup folder on the external hard disk > selected encription > and saved. It is now taking an age to make a Disk Image (whatever that is).
Once it has finished, do I treat it like a normal folder? Does it move the original backup into the Disk Image, or should I delete this? How do I use it?
Thanks

Thanks for response.
I want to backup my entire computer onto an external hard disk. I've done as you said: made a Disk Image of my Hard Disk (password protected, read/write). I can now copy that to my external hard disk.
I now intend to backup my Users > Home folder every week. But I can't drag my Home folder onto the .dmg file to copy and replace the old Home folder.
Does this mean that I have to double click the .dmg file, to get the disk icon to appear on my desktop. I then drag my Home folder to this folder to copy and replace the old Home folder. And amazingly this links to and updates the .dmg file.
Won't this take ages? The .dmg file has to open (process 1), the file has to copy and replace the old Home folder (process 2) and then somehow the disk icon on the desktop has to link back to the .dmg file (process 3)
Can I not just password protect the entire external hard disk or password protect a folder?
Thanks

No app on the iOS device is required.
- If you previously turned on FIndMyiPod/iPhone/iPad on the iOS device in Settings>iCloud and wifi is on and connected or cellular data is on and connected for, on a computer browser go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up or continue to show off-line.
- You can also wipe/erase the iOS device and have the device play a sound via iCloud.
iCloud: Erase your device
iCloud: Use Lost Mode
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the device and report to police and carrier if iPhone or cellular iPad
- There is no way to prevent someone from restoring the erase (it erases it) using it unless you had iOS 7 or later on the device. With iOS 7 or later, one has to enter the Apple ID and password to restore the device.

What is recommended as virus protection for Mac?, What is recommended as virus protection for Mac?

What is recommended as its protection for MacBook pro.

See my Mac Malware Guide. Although you certainly can do without anti-virus software, there is malware out there, so you do need to be aware of how to stay safe online.

With ransomeware becoming a threat, what is the best virus protection?

With ransomeware becoming a threat, what is the best virus protection? I am running OS-X Yosemite and want to protect against virus intrusion. What are the best approaches, including what virus protection software?

Ransomware and viruses are unrelated to one another, so your question is logically inconsistent. To learn about "ransomware" read "Ransomware" web pages.
What are the best approaches, including what virus protection software?
The best approach to Internet security does not rely upon any third party virus protection, for the reasons that follow.
There will always be threats to your information security associated with using any Internet - connected communications tool:
You can mitigate those threats by following commonsense practices
Delegating that responsibility to software is an ineffective defense
Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iCloud, iTunes, or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
The same precaution applies to Adobe Flash Player. Newly discovered Flash vulnerabilities appear almost weekly.
Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver "free" movies or other copyrighted content that is not normally "free".
The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.
