So I recently installed an Overland Arcvault 12 tape library on a server to back up /var/log/ and /home. The server is an out-of-box RHEL 5 install, with all packages selected, in an isolated lan, with no package updates. Also, this is a live server that cannot be brought down for backups, and some files may be actively in use during the dump - just gotta live with it.
Since I know EL5 and C5 are the same, and the level of support I get from RH is actually less effective and slower than resources such as this list, I'm looking here, first.
Up to this point I was backing up to a USB-mounted external 1 TB hard drive.
I was using a script containing:
/sbin/dump -0v -z2 -f /media/usb_drive/dump0 /home
I played with restore on that, and it tested fine.
For the tape, I thought it would be nice to add /var/log (should have done it before, but didn't think of it...)
Trying to adapt the knowledge to a tape library...
/sbin/dump -0 -v -z2 -f /dev/nst0 /var/log /sbin/dump -0u -v -z2 -f /dev/nst0 /home
I have a cron job that dumps the results to /var/log/dump.log, and a review of the log file claims all went well. Now for the restore...
I just tried playing with different options of restore, but could not successfully restore anything. I ensured I was in a scratch area so as to hopefully not overwrite current files.
What is the proper procedure for dumping and restoring now? Should I be dumping to /dev/nst0/dump? What restore commands would I use to recall a file?
I'd like to keep things as simple as possible - people have suggested legato and amanda, but for now, I would think/hope dump and restore would work.
Thanks.
