[K12OSN] offsite backup?

[Paul Lemke]

That's a good idea. I'll just get 2 and rotate them every other week or
something. 

Does fc5 have any issues reading USB hard drives?

As you said, they are cheap. Buy two and rotate.

I'd think it's reliable enough if you have some redundancy. Maybe
Mon-Wed-Fri on one, Tue-Thu-Sat on the other?

A slow uplink might be OK if you're only transferring diffs over the
network (see software recommendations) and doing it only during off-peak
hours (at night). Maybe not too expensive if someone trusted can either
host at home or at a partner organization.

Some things to check out:
backuppc.sf.net
www.nongnu.org/rdiff-backup/
www.dirvish.com
www.rsnapshot.org/
www.mikerubel.org/computers/rsync_snapshots/

These might be applicable to either offsite or rotated removable hard
drives. Whatever you do, test your backups. Only thing worse than no
backups are backups you _think_ work, but really don't.
