Backup- miscelaneous question

Hello
1) From what I read until now the cold backup
is the backup taken while the database is closed and
hot backup is the backup taken while the
database is open ( user are connected to database).
Except the case in which the database should be
available non stop is there any reason for which I
should preffer hot backup instead of just copying the
datbase files ( cold backup) while it is closed?
- Very large databases where copuing all the files will take a long time.
- Using hot backup means that you are in ARCHIVELOG mode and this mode is mandatory if you don't want to lose data and/or transactions ...
2) In a web page have find the following
expression:
"you should not backup the online redo log
log files when doing hot backups".
Backing up a database does not mean that you have to
back up all database files ( including redo files)?
Hot backup is only available when you are in ARCHIVELOG mode and then your Archive Log is the backup of your redo log files
3) What information is contained by a dump file
(export the database)? For example from this file can
be extracted the database structure or even recreate
the database if for some reason that will fail.
You can't recreate the database from export file. You have to create the database separately before importing to it.

Hard drive failure! New hard drive/Time machine backup/iPhone questions

Hello,
I have a 2011 MacBook Pro who's hard drive failed (rather acutely too, I do use disk utility to check it's health regularly) and I bought a replacement to install (SSD!). I have a bunch of questions but have only found partial answers in searches. Maybe it's best to list them:
1. I'd like to do a fresh install of the OS X using OS X Recovery because I'm concerned my Time Machine backup is partly corrupted. I hadn't updated to Mavericks, will I be able to install Mountain Lion? If not: will this be a problem with my backup files?
2. Say the OS X Recovery works, how do I use Time Machine to restore things like my iTunes library/iMessages/email/iPhoto library etc? In other words: just the data I can't get any other way (I hope it's not too corrupted). And/or should I use my iCloud backup on a few of these (iMessages/contacts)?
3. Do I need to set up the new OS X install with the same account names/home disk name etc. for the restored backup files to function?
4. Is this going to f'up iCloud or vice versa?
5. Finally, how do I sync my iPhone to the "new" computer without erasing the iPhone (which had an iOS update since my last backup to Time Machine). Or do I have to restore the iPhone too.
6. How come Apple doesn't have a mobile theme for their website yet?
Any help would be much appreciated,
Matt

Do you still have the original System Reinstall DVD set that came with your Mac?
If you created that Lion external drive you have from YOUR Mac, when Lion was installed on it, and it also contains a Recovery HD partition you can use that to boot to the Recovery HD and reinstall Lion on the new drive. And or Clone that external to the new internal drive you installed.
Right since your Mac came with Snow Leopard you can't use the Online Internet Recovery system to reinstall Lion, as your system didn't originally come with Lion, but you should still be able to boot to it to do diagnosic things like using Disk Utility, going to the Net to get help and even Restoring the system from a Time Machine backup. But you will get an error if you select Reinstall Mac OS X. The firmware update is usually applied with system updates.
If you created a New Time Machine Backup when any of the Download Only version of OS X were installed on your internal drive Time Machine, the system, Copies over the files needed to boot the system from that backup drive. If it was a care over backup from when Snow Leopard was installed is might or might not be bootable. Only way to tell is to connect it and at startup hold down the Option key to get the Boot selection screen, IE The Boot Manager screen, and see if it shows up as a Boot Source. If it does thenn it contains the files needed to get to the Mac OS X Utilities, IE the Recovery HD files.
What you should do is Boot the system from either the Time Machine backup, if it is bootable, or your External that has Lion on it, The Recovery HD if that drive contains a Recovery HD, or your Original Snow Leopard reinstall DVD that came with your Mac and then try to Restore from your Time Machine backup drive.
If that fails to restore your system properly then nyou should reinstall Snow Leopard and the iLife Apps from the Original Discs then upgrade to Mt Lion which will be in the Mac App Store under your Purchases area. Then maybe you can restore your files from that Time Machine backup.

I've had a bunch of issues with my computer (you can look at some of my other questions on these forums) which, to my mind anyway, seemed to be finally given a diagnosis when my HD crashed. It may be paranoia but there have been enough problems that I'd rather do a clean install to be on the safe side.
I have an early 2011, shipped with Snow Leopard.
I was under the impression that Time Machine can't be used as a boot drive and the OS X Recovery is a firmware update (on my computer) or hard wired in (on later computers). I might be wrong. I was planning on using the internet recovery, the HD failed right after I got some password protected files unencrypted and onto an external drive (was that necessary?) but wasn't sure if it's a problem if it installs Mavericks.
So Setup Assistant will configure my accounts the same and I don't need to worry about that? That's a relief.
Thanks for the lengthy response.

ISE 1.2 backup restore questions

Hi all,
I have been looking at the backup and restore procedure for ISE deployments and have to say I have found the documentation to be somewhat confusing in general. Whilst I get the gist of it I have found numerous areas that are grey. This question is the first of many but here we go.
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/user_guide/ise_user_guide/ise_backup.html#pgfId-1073378
Based on that link to restore a failed primary admin node I am left wondering about the state of the licensing. In a deployment that has the licensing configured to utilise the UDIs of the primary and secondary node what happens after you have rebuilt the primary from the ground up?
As far as I am aware when you run up a new node the UDI changes meaning that the license detail is no longer correct - how does this affect the rebuilt node becoming primary again and do you have to rehost the license to reflect the new UDI?

Another question I have is about the restoration of monitoring data to a primary monitoring node that has temporarily failed. As per documentation it states that a manual backup should be taken from the secondary node and restored to the primary to essentially provide the missing events during the outage. I have a couple of questions about this process:
1. What happens when the primary monitoring comes back online - does it sync up with the secondary monitoring node effectively overwriting the events the secondary has or does it just continue on its merry way?
2. To restore data to the primary monitoring node do you need to de-register the primary before restoring the backup taken from the secondary and re-join it to the deployment or do you just restore from the primary admin GUI? As far as I can see this still means that there will be a hole in the data for the period of time it takes to restore from backup.

First backup: Newbiew question

Greetings from Ireland.
I am a bit puzzled, here is what I did. I have the TC set up at 5Ghz only, and use an airport extreme in my MacPro, transfer rate is 135, more or less constant, I assume this is the "N" speed, as I had only a rate of 65 before. So that is fine.
However, I connected the TC via ethernet to a NETGEAR GS108 Gigaswitch, to which my macPro is also connected.
Now my question:
As I am running a back up at the moment, the lights on my Netgear switch indicate full activity, both lights blinking per port, on both, my MacPro and the TC. However, judging by the back up speed, it is not using ethernet, but rather the wireless. I backup 34 Gig and over ethernet this would be much much faster.
So, why do the ethernet ports show activity at all, and how can I use the backup function via time maschine over ethernet instead wireless?
Thanks Folks
Best wishes
OVS

forgot one more...
Can you use a powered USB Hub on the TC? I have a spare Adaptec Hub, it was originally used in a PC together with a USB 2.0 card to upgrade an older PC to USB 2.0
At the moment, I tried to use a unpowered Kensington USB 4x Hub, but it does not work somehow, does not send to printer, does not recognise a USB receiver etc.
What USB Hubs do you use that work?

Backup iPhone question

When I bought my iPhones and also bought a backup iPhone. It's still in the box unopened. I always buy a backup because I only have a cell phone. So I buy a backup of the phone I am using at the time. If my cell dies at 11pm, I can just put my SIM into my backup. Been doing this for years.
So. The unopened iPhone. I wanted to connect it up and update it to the latest software. Then put it back in storage for backup.
The question is:
Is it possible to take an iPhone, update it and then go back to my main iPhone? My iPhone is an 8 gig version. The backup is a 4 gig.
Do I have to activate the backup iPhone if I connect it to iTunes to update? Will this screw up my ATT account?
Can an iPhone user go back and forth between iPhones?
All other cell phones I've owned over the years I could just swap out the SIMS. The network didn't care and activation was a non-issue.
Anyone see any problems with my iPhone scenario?

This should not be a problem but you must activate this iPhone with AT&T and iTunes to be able to use it and/or update it with any available Apple updates but this will or should be an abbreviated iPhone activation process of the original since you are using an existing AT&T SIM card that is already activated. This will have no affect on your AT&T account. If an iPhone is lost or stolen, the same applies.
Once this new iPhone is activated with AT&T and iTunes, you can switch the SIM card between iPhones and you can use your iPhone's SIM card with another AT&T provided phone or an unlocked GSM phone.

Backup VHD size is much more than expected and other backup related questions.

Hello,I have few windows 2008 server and i have scheduled the weekly backup (Windows Backup) which runs on saturday.
I recently noticed that the actual size of the data drive is only 30 GB but the weekly backup creates a VHD of 65 GB.This is not happening for all servers but for most of the server.Why is it so..and how can i get the correct VHD size..60 GB VHD does't make
sence for 30 GB data.
2. If any moment of time if i have to restore entire Active Directory on windows 2008 R2 then is is the process same as windows 2003..means going to DSRM mode,restoring the backup,authoritative restore or is there any difference..
3. I also noticed that if i have a backup VHD of one server (Lets Say A) and if i copy that Backup to other server (Let Say B) then windows 2008 only gives me an option to attach the VHD to server B but through backup utlity is there any way to restore the
data from the VHD,Currently i am doing copy paste from VHD to server B data drive but that is not the correct way of doing it..Is it a limitation of windows 2008?
Senior System Engineer.

Hi,
If there are large number of files getting deleted on the data drive, the backup image can have large holes. You can compact the vhd image by using diskpart command to the correct VHD size.
For more detaile information, please refer to the thread below:
My Exchange backup is bigger than the used space on the Exchange drive.
https://social.technet.microsoft.com/Forums/windowsserver/en-US/3ccdcb6c-e26a-4577-ad4b-f31f9cef5dd7/my-exchange-backup-is-bigger-than-the-used-space-on-the-exchange-drive?forum=windowsbackup
For the second question, the answer is yes. If you want to restore entire Active Directory on windows 2008 R2, you need to start the domain controller in Directory Services Restore Mode to perform a nonauthoritative restore from backup.

http://technet.microsoft.com/en-us/library/cc816627(v=ws.10).aspx
If you want to restore a backup to server B which is created on server A, you need to copy the WindowsImageBackup folder to server B.

Using Lenovo's Enhanced Backup & Restore Questions

Hi all,
I am wondering if anyone has any experience in using Lenovo's Enhanced Backup & Restore.
My situation is that I am thinking of updating the firmware on my MyDigitalSSD 128GB mSATA SSD to the latest version. However, from what I read, the update will wipe the mSATA SSD. Also, at the moment, I have been backing up my C:\ to an external HDD weekly using Lenovo's Enhanced Backup & Restore software.
My question is if my steps below are workable and if the Enhanced Backup & Restore program will restore my system back to the latest backup?
1. Use Enhanced Backup & Restore program to backup the latest image of my system.
2. Update firmware on my mSATA SSD. All data will be wiped.
3. Use my Recovery Discs to restore the mSATA SSD to Lenovo's factory image.
4. Use Enhanced Backup & Restore program to restore the latest image.
Any comments, anyone? Thanks in advance!

You can only restore to the same hub, as the serial numbers have to match.

Backup/restore questions LMS 4.2

Hello,
I have several questions regarding data migration from LMS 3.2.1 to LMS 4.2.We will perform backup and restore procedure on new LMS4.2 server machine .
1. I am wondering what will happen with admin password aftrer restore, and all the other passwords in LMS. What will be effective? What will happen with database passwords?
2. Other thing is : LMS 3.2.1 is installed on D:\ProgramFiles\CSCOpx and the new LMS 4.2.1 is installed in D:\CSCOpx
Will there be problems during restore, because the paths on old and new LMS server are not the same?
3. When to perform the licensing? Should I apply license before restore? I think I would have to apply it before beacause customer has 300 devices and eval license iz for 100 only.
4. Does PI_CM license - Compliance Management License comes with the product? How do we get this license? I am aware that this CAAM is new feature in 4.2 version so I am not sure does the customer have rights on it. They have bought upgrade from 3.2 to 4.1 and they have valid support contract so we will go to 4.2 version.
Thanks!
Marija

Following are the answers :
1. LMS's user info and passwords are stored in cwpass file under NMSROOT\lib\classpath\com\cisco\nm\cmf\servlet, which is also
backed up with DB backup. Hence restore would bring all previous user names and passwords.
2. Ciscoworks has a mechanism which doesn't bothers the install directory. It sets environment variable as NMSROOT which is replaced by
the install directory and hence there should not be any issue. Please note that Inter-OS resotre are not supported.
3. You can apply the license anytime, but it is good to install it before backup restore, else the excess of devices, more than 100
will go to unmanaged state and will have to be brought back to managed state once lic is applied.
4. CAAM lic has to be purchased separately. You can contact lic. team or your accounts team for this.Till that time you can use it with its 60 days eval lic.
-Thanks

FCP Backup Project Questions

Hi Everyone,
Say I had several questions and was hoping another FCP user could answer them for me.
I recently had a hard drive fail that housed all of the captured video for a project that was complete, but had not yet been exported out. A real bummer.
I did not worry about it too much since it was only the captured video and audio and thought all I needed to do was just go in, select the offline files and recapture the footage. Boy was I wrong.
This had been my backup philosophy thus far, backup my project files, graphics, music, etc etc and dump all of the captured video and audio on the project, since I had the original tapes. If I needed to go back into the project I could just recapture. I developed this from other users suggestions from here.
Well on this project, when the hard drive crashed, since I had all the same files I would normally backup I assumed it would be the same deal. I have never had to go back to a backup project so I had not tested this before.
When I attempt to batch capture the original footage, some captures fine, while others come up prompting me to change a file name because one already exists and even on stuff that will recapture, it comes up saying it cannot be reconnected because the capture footage does not match. Sigh. I am puzzled by these messages since, the settings for the recapture are the same, and the file cannot exist since ALL the footage is gone.
So what I am faced with now is confusion over what is a good, solid way to backup ones projects. Am I doing something wrong when setting projects up that cause them to be such a headache to recover? Many of the projects I do are using a 24p Adavanced setting. Sometimes I remove the advanced pulldown when capturing, sometimes after I have captured. My setups, for the most part, are normally the same.
Can I start a dialogue with some fellow editors out there who have some experience here? I am real curious to know what works for you and any thoughts on what could be causing my current woes.
Thanks so much!

Ok, well here is where I am at:
I performed the XML export as suggested, but ran into the same issues. Let me give a more detailed description of the issues.
After the hard drive crashed and I lost all my captured video and audio, I replaced the drive and named it the same as the previous one.
So when I went back into my project, the normal message pops up that items are offline, etc. I hit continue past this and tried to batch capture the footage again. On several clips FCP (version 5.0.4) would come back reporting that there was a Duplicate Item Name and try to force me to rename it or skip (Why does it not give an option to overwrite??). Now in the bin there is only 1 clip with the name, so I am assuming it is picking up on something else. On other clips, it does not prompt this, but when I have finished recapturing (mind you I have left the box checked to use the logged settings) it comes back to report that the clip cannot be reconnected because the beginning or end times are different, etc, etc.
So per the great suggestions on here I exported (with the Source showing in browser) the whole thing to XML and then imported it into a new project. Same problems as before. So I looked through the Source in the browser and noticed some stated they were offline, while others stated they were on the old crashed drive. So I set them all to be offline and told it to delete the files from the hard drive.
Again I have tried to recapture to no avail.
I am now attempting to blow out the hard drive and wipe it clean, then rename it to see if I can get FCP to recapture the darn footage.
Does anyone else have any suggestions??
And furthermore, what is the best method to backing up a project?? Should I go through and take all the clips offline in FCP, deleting the footage and then as I have been doing, save the project file, graphics, etc, etc. Basically, how do I get FCP to recapture stuff if I ever have such a problem or need to go back into a backed up project again??
Thanks ALL!

Hot backup related question

Hi all,
i have a question related to hot backup
If we take a hot backup ie. alter tablespace tbs begin backup....then it freezed the datafile and all the entries happen to the redo log files.....if we a two log groups and and hot backup happens to continue from BOD(beginning of day) to EOD,then there might be a situation in which log switch happen it means it will archive the same,so how the datafile will recover the same...
here it freezed the whole datafile or only datafile header.....

here it freezed the whole datafile or only datafile header.....The crux of the hot backup done via manual cp command is that datafile is completely operational. So all the objects which can undergo changes like tables and all , they keep on working as like they used to do without the back up is on. As all the changed vectors are logged in the redo log files , so the same is true in this case also when the datafile goes into the backup mode. Oracle just freezes the header of teh datafile and freezes the SCN at that point for it to know where to start the recovery from in the order of a crash. When the file is put into the backup mode, the header is freezed and the checkpoint is done before putting the file into the backup mode. Makes sense as with the checkpointing , the related buffers for that file are put into the file , ensuring that the file now is a self consistent file.
There is no checkpoint that happens with the end backup though. The file is made in sync with the rest of the database files when the next full, system level checkopint will happen. All the changes required to make the file get in sync with the rest of the database is already logged in teh redo and archived files. So in the case of a crash, oracle just applies those to the respective file and the recovery is complete. So there won't be any impact on the recovery. Just there is one issue that there would be extra redo generation due to the first time logging of the whole data block in the redo stream to avoid the fractured block issue.

Size of backup drive question

I'm sure the answer to this question is here somewhere, but I did some searching and couldn't see it. Can someone verify that the size of the backup drive has to be equal or greater than that of the drive being backed up? In other words, I can't use a 500 GB external to back up a 750 GB internal (with only 1 partition), even if the internal has only 100 GB used, right? I'm pretty sure that's correct, just want to make sure before I get in the middle of it.

Well, it depends on what you want to use the external drive for - if you want to use it for Time Machine, the general recommendation is that it should be 2 - 3 times the size of your internal. That's because Time Machine creates backup after backup after backup until it runs out of space (it then deletes the oldest one to make room for the latest backup).
If you want to create a bootable backup, the size should be what you think your internal's size is/will be. Bootable backups are exactly the same size as your internal at the time you create it.
If you also want space for an extra copy of important files, pics, videos, etc., then you have to consider that as well. You can create more than one partition on any external - one for your Time Machine or bootable copy, and the other for drag 'n drop copies of important stuff.

Printing contacts trouble and backup confirmation question

I have two questions:
1) I am trying to print all of my Contacts. I go to the page where I can see the long list of contacts, select “All,” click on the Actions dropdown menu and choose “Print,” and then I receive this message: “Something happened while we were trying to print your request. Please give it another try.” I have been trying and retrying several times a day for more than a week. What is wrong?
2) When I was using Backup Assistant, I received a “backup complete” message each morning. Now I am apparently using The Cloud, and I never see a “backup complete” message. Is that the way it is supposed to operate?

AliceinMD,
We'll help with both of these! As Ann154 stated, you can export the contacts to a CSV file and then open them in a spreadsheet to print.
The Cloud is a great improvement over the former Backup Assistant program. What device do you have? If you access the app, and then tap on the two arrows circling each other in the upper corner everything should back up for you. You will then get a notification when a backup needs to complete.

Win 7 Backup/Restore Questions

I have questions about Windows 7 Backup & Restore. From everything I am reading, it would appear that the program performs as advertised, but some of the traits I am witnessing just don't make any sense to me, and when it comes to Backup/Restore
(B/R), things need to make sense.
Q1: I have a machine that is configured with three (3) accounts: one is a privileged account (admin), and the other two are normal non-privileged accounts (acct1 and acct2 for reference purposes). I perform the backup from the admin account, backing
up the entire machine (all accounts). The backup completes without error. If I then Restore Files to view what was saved, I am shown the admin account, and acct1 as available to restore. Acct2 is not visible! Why not? Am I not
allowed to restore this account as admin? If it is a permissions issue, then why can I see and select acct1? If I logout of admin and login to acct2, and run B/R from there, the admin and acct2 backups are visible, but not acct1. So I know
the data got backed up, but why am I not able to see all the backup accounts when running as admin? If I had a machine with 15 accounts, does this mean I would have to login to each account to restore its files when rebuilding after losing a drive?
Q2: Backups are tagged by date. If I run B/R daily, it appears that the backup is retagged with a date range. If I wait a number of days to perform the second backup, I may get a second backup entry with the new date. What algorithm is
being used to determine when to extend a backup, and when to create a new entry? Is there a trigger that I can use that will force the creation of new entry, and not extend an existing entry, or vice-versa?
Q3: Everything suggests that with multiple backups, the oldest backup represents a full set of files, and subsequent backups are incremental. Exactly what is meant by incremental. I would expect this to mean that any file that has not changed
since the last time it was backed up would not be part of a new backup. Or stated the other way, any file that has changed since the last time it was backed up would be part of the new incremental backup. If I have 4 backups, will B/R examine all
4 to determine whether a file needs to be included in the new incremental backup (I assume so)? If I have 15 backups will B/R examine all 15 to calculate the new incremental (I assume so)? If I decide to manage space and delete the oldest backup,
will a subsequent backup operation resave all my old files that have not changed since the first backup but are now missing from the backup set (I assume so)? If so, then any space gained by deleting the original backup will disappear after the new incremental
completes. Would it be better to delete only the older incremental backups to free up space?
Q4: If I were writing this program, I would expect that contained in each backup is an index to all the saved files along with their dates of existence. I would have to scan ALL backups to create an index of ALL files with their respective save dates.
I could then compare the current file path and date with the name and date in the archive to determine whether the current file needed to be included in the new incremental. If this is the case, is there some point where deleting some of the older backups
will improve the overall efficiency of the backup operation by reducing the number of backups that need to be scanned to build the current backup file list? If so, what is a good rule of thumb for the number of backups to retain to preserve program efficiency?

Hi,
First question, I'm sorry for never heard this problem, I would made a test in our test enviroment, After that, I would provide the result at here.
For other questions , I would like to suggest you read the link below for some details about system backup.

External backup drive question

We have CrashPlan, which I highly recommend, to back up our files. But I don't have a bootable clone.
And I'm about to upgrade to a new Mac OS, so I'm not about to try it without one.
Here's the question (sorry -- it's convoluted):
I need a new printer. No new Brother (my preferred manufacturer) will work with Mac OS 10.6.8. All require OS 7 or later. So I need to upgrade before I can even buy the printer.
But my 500GB hard drive (MBPro 2.2 ghz late 2008, 4 gb RAM, Intel core-duo) is crammed solid with stuff...only about 15GB free .... so I need to get rid of stuff on the drive.
I bought an external drive (1TB). Western Digital 1 TB My Passport Ultra. I was gonna just offload files on it, like photos -- that would clear out an easy 100GB.
But then I thought, "Gee I really should make a boot disk. This computer is long in the tooth and what if the upgrade fails?"
Can I make a bootable disk and also have something separate on the same external drive so I can offload photos and other files and access that when needed?
I have no idea if I can do both on the one external drive. And do I need to do wonky stuff like partitioning?
Any help would be great. A link to a step-by-step would be fantastic.
Thanks in advance!
