Is there anyone backing up OpenAFS using amanda? Is there anything
special that needs to be done, or is it just like backing up any
other file system?
I'd like to use gnutar if possible.
We are, and I've heard from a few other sites who also are. Don't
have a good feel for how many yet. OpenAFS is not just like "any
other" filesystem. In general, root is nobody special to OpenAFS.
So your backup program needs to acquire appropriate privilege to
read files. If you can do that (reauth is one way), you can just
use gnutar. But then you'll back up the file contents without the
ACLs and volume structure needed to put everything back the way it
was before the Bad Thing that happened that caused your need to
perform a restore.
First stop: read docs/HOWTO-AFS
This is just a pointer, but it tells you where to find some code we
put together a few years ago to backup OpenAFS with amanda more or
less "right". I say "or less" because there are still some
improvements I'd like to make sometime.
One new item, for those who've heard all this before. Just today
we created a new mailing list for amanda-afs users. Info can be
found here:
