Thanks everyone for all of your helpful advice. My short-term solution
is using tar, but not using compression and dumping error messages to
try to figure out what is going on.
I did find a useful web site
http://www.backupcentral.com/free-backup-software2.html
that lists all of the free software available for unix.
I was looking at amanda, which looks like about the best around, but I
was confused by a statement they made:
AMANDA supports using more than one tape in a single run, but does not
yet split a dump image across tapes.
Can someone explain the difference between using more than one tape in a
single run and splitting a dump image across tapes? I would have
assumed these were the same things. My situation is that all of the
data I want backed up does not fit on one tape. Right now I backup
different parts of the system on different nights by cron (now it is
spread out even more than before, since I have stopped using zip to
compress!). How much versatility do I have with Amanda? Can I save
half of /home in one night?
While I am asking for backup advice... We are about to switch to a 1/2
TB raid array. Right now we have an hp dlt 40/80GB backup tape system,
but we are going to have to upgrade this. Any advice on how to backup a
1/2 TB?
thanks again - you guys rock,
maria
