Here's an idea I have completely unrelated to my problem posting, looking for feedback. Goal: using single large HDDs as backup media rotating them offsite, in as simple and bullet-proof as possible a way.
Strategy: two hard drives one with the base server OS installed, install BackupPC 3.1 via package management the other set up as one big partition (probably ext3), top-level folder "BackupPC_TOPDIR"
under the latter: create conf and log move the contents of /etc/backuppc and /var/logs/backuppc contents to the above two new directories locations, and the contents of /var/lib/backuppc to the TOPDIR location itself, so everything related to BackupPC is there in one place
(here's where I need to get the proper permissions, ideally as the specific chmod/chown/chgrp commands to use - any pointer appreciated) leaving the original directories empty as mount points
use fstab to first mount the second drive at say /mnt/sdb3, then (using bind mounts) /mnt/sdb3/BackupPC_TOPDIR at /var/lib/backuppc then (more bind mounts) /var/log/backuppc at /var/lib/backuppc/log and /etc/backuppc at /var/lib/backuppc/conf
I should be able to clone this second drive to another two, and transparently swap them out, effectively creating three entirely independent but functionally identical BackupPC servers. One is live, the second on the shelf on site, the third stored at a secure offsite location. Replace A with B, take A offsite and bring C back to sit on the shelf, next time replace B with C etc, rinse and repeat.
Only downside is if the boss needs to restore a specific day's version of the corporate vision statement RIGHT NOW and that happens to be offsite, but that seems a small price to pay for the simplicity of the scheme.
Obviously only works as long as everything fits on one disk - in my case not a problem. I suppose another server with the full historical set on LVM-over-RAID array would handle both those issues, as long as the single drive held at least one full snapshot, I still think the bullet-proof-ness of my scheme is better than an off-site-server mirrored over a WAN.
Feedback on any gotchas, and the permissions details would be greatly appreciated. . .
