Yesterday I restored my iTune library from a backup after an external drive gave failures. The only thing that changed is the firewire drive is now 1Tb instead of 250Gb. At the moment of restore I could still see old backups from months ago.
Today, Time Machine complained about it not having enough space. So, I opened up the Time Machine interface to remove some very old stuff.. Surprise! All backups are gone! Only a full backup from yesterday night is there, from which I restored my tunes..
Very, very annoying. Looking around, I can’t find anything back in Finder or in the Terminal. My Air’s sparse bundle is still there (backed up through network), but before 2009-02-21 it’s all gone. Did I say this was annoying? I’m not trusting it to much anymore (you should never trust any backup anyway).
