as an option? any thoughts?
I wanted to recommend you to take a look at Bacula, than I saw it is already
on your list. Bacula is very nice peace of software. It can do almost
everything that very expensive products from Veritas and Legato do. The only
thing it is missing is a nice GUI. You'll need to configure it using your
favorite text editor. It can be a bit complex to configure, however it does
come with good default configuration files that you can use to build on.
However, you should read documentation and really understand how Bacula works
before deploying. It is much more powerful and therefore also much more
complex system than Amanda.
I'd take a bit of an issue with your last statement, there. Amanda's best
feature is its *very* powerful scheduling algorithm. Essentially, amanda
tries to ensure that, within the parameters you set for time between
full backups, each night's backup run backs up about the same amount of
data. This is very handy when you are, as I am, backing up ~10TB of data
to small (even LTO3 is small when you're talking that much data) tapes.
AFAICT, all scheduling with bacula is user driven. Thus you end up with
the traditional *nix incrementals on weekdays, fulls on the weekend
shuffle where your fulls can take a *long* time. And that doesn't work so
well, e.g., when you're dealing with grad students who work on weekends.
If I'm wrong about bacula's lack of any sort of scheduler, I'd be happy to
hear about it. But, for me, amanda is a rather powerful and complete
solution -- moreso than bacula.
