Re: amanda in an Andrew environment?

2002-07-15 Thread Mitch Collinsworth


We've been working on amanda backups of AFS here, but not using
AFS's backup system.  We found that too painful.  We ended up building
our own dump program that wraps around vos dump.

It's often said that DUMPER-API is coming, but I've seen nothing to
suggest there's been any recent progress.  Some preliminary work was
done on it a while back but I think it stopped.

I know very little about Coda but I don't see a need for an AFS
backup that produces BSD dump-format output.  We also wanted to be
able to restore AFS dumps into non-AFS filesystems, but we were able
to build a restore program that does this.  It's just a matter of
being able to decode the vos dump format.

amanda in an Andrew environment?

2002-07-11 Thread Ronald O. Christian


Let's say that for whatever reason an organization is a heavy user of
the Andrew file system.  (No NFS at all -- all AFS.)  There are
apparently locking issues with commercial backup software backing up
Andrew file systems.  (or so I've been told) The company in question
has been using Budtool forever, and hated every moment of it.

How would amanda benefit this situation?

Thanks.

Greetings,

Amanda does not backup data.  She uses the filesystems native backup
utility, usually some form of dump.  So this way it is not amanda that
archives the data it is the filesystems utilities, which should account
for the locking issues.

HTH,

Drew
