I'd just like to add that it is also possible that your disk volumes aren't 
the problem, but your db server is either filling up the filesystem it 
lives on, or filling up filesystem where it holds temporary db stuff.

Go into the config for your db server and look at where it is putting 
everything (temp tables, temp space, logs, log files, etc).  Make sure you 
have plenty of extra space every place your db or bacula writes.

If you're doing spooling with bacula, make sure that isn't filling up a 
filesystem.  Also check where bacula is doing attribute spooling.

Check the server logs found in /var/log (especially the messages file) for 
write errors.  If your server hasn't logged the problem then you'll have to 
monitor it more closely during backups to determine what's going on when 
there's a failure.
