I have one Mac and my goal would be to backup to one location, then have backups of that backup that could be recovered from. The backups of the backup would then be kept offsite. So this is what I'm trying to do and how it doesn't quite work so if anyone knows how to fix it, or even if there's a completely different idea that would be better, I'm all ears. I currently have Time Machine set to backup to a network share (SMB) that exists on a Fedora 12 machine. What I would like to be able to do is backup the backup so that I can store it off site. What I've tried to do is create two network shares and they exist in the folders .../time_machine and .../time_machine_2. To copy I do something like (on my Fedora box) cp -R .../time_machine/* .../time_machine_2/ (I make sure to disable backups on TM on my Mac before I start) Then I point my TM to the share on .../time_machine_2 and 'Enter Time Machine', but it gives me an error. I can fix this by doing a backup and then entering TM, but it doesn't seem like that should be necessary and hints to me that something is wrong.
