iPhone
If you’ve got an iPhone, there’s a good chance you’ve already sat through—and been annoyed by—its backup routine. iTunes updates your iPhone’s backups at every sync, which makes users’ lives a bit easier, and guarantees some kind of safetly net by default. But! As with most fully automated systems, iTunes backup is kind of enigmatic. It just sort of… happens, and it’s not clear what you’re saving, where it’s going, and how to keep it truly safe.
What it’s doing is performing a full backup equivalent. In other words, instead of just mirroring your entire device as a big image file, it’s extracting all the useful bits, so it can restore your iPhone as if it had undergone a full, mirrored backup. This includes, among other things, bookmarks, app settings and data (including in-app purchases, but not the apps themselves), contacts, call history, Mail accounts, SMSes, videos and photos. In other words, pretty much everything. Backups are performed automatically, and restoring to one is a simple matter of plugging in your iPhone, alt-clicking on its icon in iTunes, and selecting “Restore from Backup.”
Crucially, this is different from selecting “Restore” in the device summary page: doing that will revert your device to a clean, factory-default image, which will delete all your personal data. Which isn’t what we’re trying to do here! (In fact, it’s the opposite!) If you attempt to do this, you will be prompted to perform a backup, which should be a red flag.
iTunes stores its backups as archived files in semi-cryptic directories, so if you want to pull them out of the closed iTunes system for proper backup, i.e. to an external HDD or online storage solution, you can find them here:
- On a Mac: ~/Library/Application Support/MobileSync/Backup/
- On Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
- On Windows Vista: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
To add a backup to iTunes, simply copy it back to its default directory, and it should show up as a restore option, labeled by date, when you’re setting up a wiped or recently capital “R” Restored iPhone or iPod Touch.
