>>>Has anyone tried doing afs dumps on a jukebox?
Yes, we have an Exabyte 10i that we do afs backups on. In AFS 3.1
I modified butc to look into a file /usr/afs/backup/config to
see if the requested dump name was configured. If so, load
the appropriate tape and go without prompting the operator. I
also added a reauth wrapper to butc to keep it authenticated.
Backup dump commands simply ran out of cron. I loaded new tapes
every Monday morning... It worked very well.
AFS 3.2's butc actually reads the tape label before it prompts
the operator and then only prompts if the wrong tape is loaded.
It would be fairly simple to have cron load the right tape in
the drive before the backup dump command is given. Authentication
issues are the same for butc 3.2 but now the backup dump commands
themselves need to be run authenticated (which is a good thing!)
All in all it makes robot backups possible without any software
modifications!
Our Exabyte 10i came with VAR added software to concatenate
multiple dumps on a single tape. I'm hoping, when I get some
free time (ha!) modify butc again to allow for multiple dumpsets
on a single tape so I don't have to use a whole 5 Gig tape for
500M of incremental data. However, I haven't even looked into it
to see how difficult it would be. (sigh!)
