After struggling to find a good backup solution for my home network, I decided upon Dantz's Retrospect.
http://www.dantz.com/
It is a cool application, even with it's slightly confusing user interface. What I like most is it's network ability, scheduling ability, backup to CD or DVD, and self booting disks BUT most impressive is it's ability to not duplicate backup files.
What does that mean (duplicate backup files?) Well, let's put it this way... let's say you have three machines (two desktops and a laptop) and they all have the same fonts installed... when Dantz builds it's backup catalog it won't duplicate files it already has backed up if they are identical. So instead of having 150 fonts backed up 3 times on your home network, you'll only have one set of 150!!! Same goes with system files too; that's where a HUGE space savings can come from.
Of course, all this power is tempered by the user -- if all you is make backups to DVD, well, then it can't possibly use that "no duplication" feature... but all in all.. if you want a powerful application to do backups this is got all bases covered.
Oh... did I mention Mac support and data verification?
This is one amazing product. I couldn't believe all it could do until I got my hands on it!!!
