Available for FreeBSD also are "amanda" and "bacula" (both in ports).

One issue is whether or not you have to back up NT/Win2K/XP clients and
servers. There is no easy way that I know of to use UNIX backup software
to do a complete backup of MS NT and NT-derived boxes since you can't easily
back up the registry. If you are supporting Windows boxes then you'll need
to add something Windows-based for disaster recovery; this could be
MS backups to a file or even using Norton Ghost to make an image of the
entire disk, and then using smbtar to copy new and changed files.

I don't know much about Macs, but assume that the conversion of MacOS to
something which is a UNIX derivative will result in Macs being backed up
using UNIX tools. A simple solution is to use netatalk (in ports) to
create a FreeBSD volume Mac clients can use, use Mac tools to back them up
to FreeBSD, and then write the files to tape using dump or tar.

You can write scripts using dump, tar, and smbtar to back up a heterogenous
UNIX/MS Windows network (assuming you do something else for MS Windows
disaster recovery).

If you have a large network with more than one person administering backups
then you may want to look at "amanda" and possibly "bacula", both of which
are in ports. "amanda" works best with a large spool disk somewhere big
enough to store a complete dump; it can control loaders/robotic changers.
I don't have experience with "bacula" but know the developer has been active
on the freebsd-scsi newsgroup.

I've used a custom script using a combination of dump, tar, and smbtar here
at home to back up three FreeBSD boxes, two MS Windows PCs, and one Mac for
several years; the tape drive is an ADIC VLS DLT changer controlled using
"chio" (requires kernel mods).
