Restore iOS device from backup with limited disk space iOS devices
iTunes stores iOS device backups in ~/Library/Application Support/MobileSync/Backup. Each folder within the Backup represents a different "backup" that will be presented as a possible restore source when restoring an iOS device.

In the process of restoring from a backup, iTunes migrates the data from one of those Backup folders into another, sibling folder, that will naturally end up being the same size.

Because you end up with two distinct backup folders, it follows that in order to restore an iOS device, you need to have at least as much free space on the device as the size of the backup subfolder. In my case it was more than 50 GB.

In order to restore my iPhone, I needed more than 50 GB free on the disk where iTunes finds my backups, so I copied the backups folder to another disk with lots of space, then made a symbolic link to it at the original location:
% cd ~/Library/Application Support/MobileSync
% cp -r Backup /Volumes/BigDisk/Backup
% mv Backup Backup-original
% ln -s /Volumes/BigDisk/Backup ./
(Replace the volume and folder names by those on your hard disk.)

Now when I open iTunes I can restore from the backup and iTunes does all that work in /Volumes/BigDisk/Backup.

Dan's problem is interesting, and something that would prevent a restore if he didn't have a second disk and the knowledge to do the above. It's surprising that the restore process will actually fail in such cases. With lots of Macs having SSDs, excess storage space on the startup disk is now rare for many people.]

Restore iOS device from backup with limited disk space
Authored by: lagreca on Sep 16, '12 03:18:50PM

This used to work for me but recently stopped. Now when I open a terminal window, I get this error:

Last login: Sun Sep 16 15:12:30 on ttys000
-bash: $HOME/.ssh/config: ambiguous redirect

If I go into my .profile and comment out the tab completion line, then open a new terminal window, the error disappears...

Could it be my recent upgrade to Mountain Lion? Any suggestions?
