What's the point of Backup & Restore??
I've been using iPhone since the first generation, but for the life of me, I can't figure out the real purpose of IOS's backup and restore function... For instance, let's say the iPhone is last backup to iTunes two weeks ago, and then one day, there's a corrupted data file on one of the app, and you decided to do a restore from backup and get the data working again. Within the last two week, there're also tons of other data/contacts added and you don't want to loose them, so you do a backup and sync first, but as soon as you sync, it REPLACES your old backup with the new! In another words, if you want to restore from backup and get the corrupted file back, you'll loose whatever added on your phone for the past two weeks, or you'll just have to forget about the corrupted data. So what's the real purpose of iTunes backup? Shouldn't it create more than 1 backups so that you can go back in case something bad happens to the one and only backup file??!!
We read it. Apparently, the concept of doing regular backups is foreign to you.
If you can't afford to lose 2 weeks worth of data, then back up more often, or, as has already been suggested, back up to iCloud.

ok im confused now.. What is the point of backing up and restoring your iphone with icloud, when to restore your iphone you have to plug it into itunes anyway? you might as well just restore it from there then shouldnt you?
when to restore your iphone you have to plug it into itunes anyway?
But you don't. You can restore your phone data direct from iCloud wirelessly without a computer. -
Ipod has been playing music in my car the past two years. new computer this year and new email address. Backed up to cloud. change ID on itunes. Music on my ipod disappeared. Shouldn't it be on the cloud somewhere?! What's the point of this cloud? And is it b/c I can't seem to change my icloud ID to the new one on my ipod settings?
Music is not stored in your personal iCloud account, or in your device backup. Music purchased from the iTunes store is in available for redownload as explained here: http://support.apple.com/kb/ht2519. Music from other sources such as your CDs should be in your iTunes library on your computer and can be synced back to your iPod from there.
To change the iCloud account on your device you have to delete the exsting account, then sign back into the new ID. -
i have recently purchased the highest storage but was unable to backup my phone via icloud, the button on my iphone to backup on icloud is grey out, anyone knows how to resolve the problem? What's the point of purchasing the biggest storage?
First check that your device is correctly connected to the wifi/internet (settings > wifi)
If your back up continually fails, you might try turning off back up on your mobile device (settings > iCloud > storage & backup) and then deleting the backup file from iCloud by swiping the backup file on the mobile device (settings > iCloud > storage & backup > manage…) and then turning back up on again.
If this doesn't help, try turning off some items for back up in a pattern to try to establish if your problem is being caused by specific data on your device.
Being able to back up to the cloud can be very useful, especially if you don't have access to a computer or have infrequent access to one, however unless you specifically need to use iCloud for back up, you will find backing up to iTunes significantly more convenient and possibly more reliable.

What's the point of redo logs?
Why does Oracle bother writing everything to redo logs? If it's going to write data changes to the disk, why not just write them once to the data files and be done with it? What's the point of doing it twice? And if it's a redundancy thing, why not mirror the data disks?
Hemant K Chitale wrote:
How would you backup a database while it is in use ? You can't lock all the datafiles to prevent writes to them. Yet, transactions may be updating different blocks in different datafiles even as the backup is in progress. Say your backup starts with datafile 1 (or even datafiles 1,2,3,4 in parallel) at time t0. By time t5, it has copied 20% of the datafile to tape or alternate disk backup location. Along comes a transaction that updates the 100th block (somewhere within the 10-11% range) of datafile 1 and also the 60th block of datafile 5. Meanwhile, the backup continues running, already having taken a prior image of the 100th block and not being aware that the block has been changed. At time t25 it completes datafile 1 (or datafiles 1,2,3,4) and starts backing up datafile 5. Now, when it copies the 60th block of datafile 5, it (the backup utility) doesn't know that this block is inconsistent with the backup image of the 100th block of datafile 1.
Instead of 1 transaction imagine 100 or 1000 transactions occurring while the backup is running.
Surely, Oracle must be able to regenerate a consistent image of the whole database when it is restored ?
That is what the Redo stream provides. The Redo stream is written to Archivelogs so that it can be backed up -- no Archivelog file is "in flux" (particularly if you use RMAN to backup the Archivelogs as well !).
Had Oracle been merely writing to the datafiles alone, without a Redo stream, there is no way it could recreate a consistent database -- whether after Crash Recovery OR after Media Recovery.Interesting point about how redo logs facilitate backups. So what you're saying is that the redo logs help keep the data in the actual data files in a consistent state by only writing full transactions to them at a time. Presumably Oracle will either write out the redo log data to the data files before a backup or will at least prevent the redo logs from writing to the data files during a backup. I always wondered how databases got around that problem of keeping the system available for writing during a backup. I wonder how SQL Server does it.
Hemant K Chitale wrote:
Now, approach this from another angle. A database consists of 10 or 100 or 500 datafiles. You have 10 or 100 or 1000 sessions issuing COMMITs to complete their transactions, which could be of 1 row or 100 rows or 1million rows, each transaction of a different size. Should the 1000 sessions be forced to wait while Oracle writes all those updated blocks to disk in different datafiles -- how many blocks can it write in "an instant" ?
But what if Oracle manages to write much less information -- the bare minimum (called "change vectors") to re-play every transaction to a single file serially ? That would be much faster. Imagine writing to 500 datafiles concurrently, having to open the file, progess to the required block address and update the block, for each block changed in each file VERSUS writing much lesser information serially to a single file -- if the file is full, switch to another file, but keep writing serially.As to your second point, I don't really have a good enough understanding about the format of redo logs vs. the data files to follow you totally. Are you saying that it takes more time to write to the data files because you have to find the proper place in the B-Tree before you can write to it? And that doing that is slower than just opening the redo log and always appending new information to the very end? Maybe so, but it seems like all transactions having to write to a single redo log in serial would slow things down since there would be a ton of contention for one file. Whereas with the data files, you could potentially have several transactions writing to different files simultaneously (provided you hardware would support doing that). And it seems to me like a change vector would contain a lot more information than a field value, but, like I said, I'm not really familiar with the format. -
What's the point of FileVault?
Of the many recent changes and updates that Lion offers, FileVault has me a little baffled. What's the point of it? Does it allow me to encrypt my files and folders with a password? If so, I haven't seen that option yet. After turning on FileVault, Lion started the process of encrypting my files (so it says) but without the option to enable a password for folders and programs, I'm not sure I understand what purpose it serves.
I use FileVault on all of my systems, which include two MacBook Pro systems (one with dual hard drives), a Mac Mini, and an XServe, and have enabled it on numerous other Macs that colleagues have used, and also enable encryption on most of my external hard drives.
You can clone your encrypted drive, though you might have troubles doing block-level clones. Once the drive is unlocked and mounted the system treats it as any other drive, and you can use Carbon Copy Cloner or another cloning tool to file-level clone your drive. The problem with cloning Lion drives with file-level cloning is you will not copy the hidden Recovery HD partiton, but this hurdle is present regardless of whether or not you have FileVault 2 enabled. However, it only takes a few more steps to restore the Recovery HD partition when cloning or restoring your system from backup (it just takes remembering to do so, since cloning is not officially supported by Apple as a backup/recovery routine).
Installing new applications and managing documents is seamless, and is the same as if you install them on any other OS X system. The encryption happens underneath the OS, so OS X, documents, and applications you use are unaware of it and work as they would on any system.
Your concerns about losing the password are good ones, but if you already set your system to use the login window instead of automatic login then there is no difference (the regular use of the login window ensures you remember your password). The same password is used to unlock the drive and then log into your account once the system is booted. The difference with login is that you will need to specify the users who are able to unlock the drive (done in the FileVault system preferences). If a user is not, then the initial login window will not show that user account, and to get to that account another user will have to log in, and then log out so the unauthorized user can access his account.
In terms of performance problems, I've not seen any in my uses (primarily office and computational analysis with programs such as Igor Pro, Matlab); however, I use SSDs in my systems so this greatly increases overall performance and results will likely be different if you are using the slower classic HDD technology. -
What is the point of syncing apps with iTunes?
I have an iPad & iPhone.
In older itunes the updates on one device would sync to itunes. but now what is the point of apps in itunes other than to waste space? if i backup a device, all apps seem to come from the internet. if i update then don't sync to itunes on pc so i end up download all updates 3 times (ipad/iphone/itunes).
Should I just delete all apps from itunes and same space both on hdd and on network (since i backup my itunes folder).
note that I have 300mbps unlimited internet.Is the device backing up to iTunes on the computer or iCloud?
If backing up to iTunes on the computer, any content purchased from iTunes (apps, media, podcast, etc) will transfer during the backup/sync process.
If backing up to iCloud, content does not transfer automatically.
The purpose is to have a local backup of content. This is beneficial in the event that content is removed from iTunes and the user wants to reinstall or restore the device. -
s there a way to resort an ipod touch to the point before a restore was done on it? It is telling me there is nothing in the icloud and I need to reset it back up. The reset was done before I could backup the icloud and itunes to the computer and it wasn't done with my permission.

What's the point of recovery partition when I have to DL the whole thing anyway?
Well I was supposed to sell my Macbook Air today.
I tried booting CMD-R into the recovery partition and instead it went to some online thing.
So then I booted Option, into the recovery partition and clicked on Reinstall Mountain Lion.
Next thing ya know its got me logging into the Apple Store and now it has a 7 hour download.
So what is the point of the recovery partition if it can't do a fresh copy of Mountain Lion? What exactly is it to help me recover from? What if I was in the hills of Indonesia and tried to do this?
Any now I can't sell this thing until tomorrow as I have a seven hour download wait ahead of me. Had I knows, I would have let that be the new owners problem. Or somehow made a backup of ML previously.
Silly Apple. Always advertising something so great that turns out to be useless.The silly part is not alerting the user that when you download and install that the .ESD installer package will be deleted and to make a copy of it.
The system you download - guesstimates can be way off - check with speedtest.net - is associated with YOU and your Apple ID and the best thing to do is any OEM material and a blank hard drive - and printout of ML Recovery Mode tech article on doing an internet based install.
Yes you could have setup a 4GB installer flash drive or on your hard drive. Yes they could maintain that 4GB on a larger Recovery partition (it is less than 1GB).

What is the best & cheap backup solution for a macpro laptop?
What is the best & cheap backup solution for a macpro laptop? easy & simple to use
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components: 1. A Time Machine preferences panel as part of System Preferences; and, 2. A Time Machine application located in the Applications folder. It is used to manage backups and to restore backups. Time Machine requires a backup drive that is at least twice the capacity of the drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
Synk Pro
Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Although you can buy a complete external drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
WiebeTech
Firewire Direct
California Drives
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver. -
What is the point of a back-up?
After updating my 4s from os 6.1 to 7 I lost all my apps and my music, why are music and apps not included in a full phone backup? What is the point of a backup if everything will be wiped and cannot be recovered?
There IS "warning" or information about what is stored in a backup. See: http://support.apple.com/kb/ht4946.
Apple does make the assumption that you will keep your music in iTunes on your computer, because if you don't the next time you connect the phone to your computer and sync the music will be erased. Or if you don't that you will take advantage of iTunes Match for music not from the iTunes store.
The point is why didn't you keep the music in iTunes? It can't be because it takes up too much space, because if your music was in your backup it would take up just as much space. -
I am extremely upset. I purchased my iPad in SA and now I am in Greece. I cannot download free apps as I get a message that the apps are not available in the SA store and only in US stores. When I change to the US store the same thing happens. What is the point of having an iPad if I cannot use it worldwide??? I feel that I wasted my money purchasing it as I specifically purchased it to use when I travel. How can I get access to all the available apps and why are they restricted.
You can use your iPad worldwide. However, each AppleID is tied to
a specific country's store. To use the AppStore in any country, you
must be in that country and have a credit/debit card issued by a financial
institution in that country with a verified billing address in that country.
It is the developer's choice which AppStores he makes his app available
from, and some countries prohibit certain apps.
To make a purchase from the US store (including downloading a free app
available in the US store), you must be in the US and have card issued
in the US with verified billing address in the US.
You can use your purchases from the SA store worldwide, but you
cannot make purchases in other than the SA store unless you meet
the aforesaid conditions. -
What is the point of the download window if you use stacks?
Greetings,
One of the most annoying things about the download window was the fact that the window always hung around after completing dowloads in Tiger when using safari. To me, that was just a time waster of always pressing Apple+W to close that window.
When Leopard was released, I was excited to realize that one function of the download stack was to recevie downloads from safari after completed. However, after completion, the download window still sticks around and I still have to close it... then navigate to my stack of downloads to mount the image. What is the point of the download window is I use stacks now? Why can't the window disappear after completion?
//CheersAaargh!! Me too - it's so annoying! Firefox has a downloads window as well - I just don't see the point of it. I didn't like it in Tiger either.
As a way to see the progress of downloads, it's fine, but it should at least close when all the downloads are finished, and completed downloads should not display.
Ideally it should look & work exactly like the Copy window in Finder - the one that comes up when you are copying or moving a large file or number of files from one folder to another.
Is there a hack that will make it work like that? -

Hello Pushtheriver,
After reviewing your post, I have located an article that can help in this situation. It contains a number of troubleshooting steps and helpful advice concerning iCloud storage issues:

This may also help:
Understanding iOS device capacity
You can sync and download many different types of content on your device. Some types of content (such as music and videos) typically take more space than others (such as notes and books). The amount of space taken by an app depends on the app's purpose; complex or graphically intense apps usually take more space than simpler apps.
If your device is near its capacity, you can remove some of the less used content to make room for more.

I am a student coming from Hong Kong to London for postgraduate study. Before I left Hong Kong, I decided to buy a netbook for my lecturers in the UK. Lenovo s10-2 was chosen because the version available in HK comes with 6 cell battery with international warranty and Lenovo Protection Service (against accidental damage).
This is the first Lenovo machine for me. All was well and I was starting to appreciate Lenovo. Suddenly, the LED screen started to flick with white lines moving across the it, just two weeks after I bought it from Hong Kong.
Yesterday, I called the UK support line who initially suggested replacement (because the purchase is last than 30-day old). However, when the agent found out that I bought the machine in Hong Kong, he said I could only get it repairs. Fair enough.
I packed the netbook this afternoon ready to ship it to the repair center. Being not sure about whether or not my proof of purchase was needed, I called the support line again. This time, the agent gave me a "friendly warning" or maybe a management of my expectations.
I was told that Lenovo believes that there is a 99.5% chance that these type of problems are due to “internal damages" caused by users! I was also advised that sending the machine in for repairs risk myself getting into paying 230 pounds (pretty much the purchase cost) to get the LED screen fixed because it is likely to be not covered by warranty. On top of that, I would have to pay 65 pounds even if I want my netbook back after inspection without getting fixed because again, 99.5% chance that "damages by users" would be concluded!
What's the point of warranty? Totally unacceptable. Any thoughts? Should I take the risk?
I only got the machine just over two weeks ago and used for less than 10 times!seblee,
This bears a bit of looking into to provide you the best answer. Sometimes, the accidental damage policies are only valid in the home country, and I would like to check. If that were to be the case, you would have replacement or repair options in HK, but standard warranty terms would likely apply in UK.
Your situation sounds exceptional, and I'd like to look into this and see what can be done.
Can your send me a private message with your contact information and the serial number from the bottom of the unit?
Sorry that you are having this trouble. Will see how we can help.
