+1 for backuppc (although I've never used amanda).  Its scheduler is
fairly smart.  If a machine (backuppc calls them hosts) is not available
for backup, it tries again later (default is every hour).  You can
configure blackout periods when no backups will occur, and you can
configure rules to ignore the blackout periods (say, if a host hasn't
been backed up in 3 days).  

It pools common files, so if you back up /etc on 10 identical machines,
it's only going to save a single copy.  But during restore, the file
pooling is transparent to the user.

I've used backuppc to back up locally and off-site (over the internet,
using backuppc's rsync support).  It works really well.

You can give users access to certain hosts, allowing them to manuall
trigger backups and restores.  Or you can keep that as an
administrator-only task.
