Re: Backup systems: opinions wanted



I use bru 2000 and I am _very_ happy with it.
I also us cpio to copy my whole filesystem(/) to a different partition
(/snapshot) to have a online read-only backup of files.
You could get by with cpio but I like the tape verify and features of bru
2000. Take a look at www.estinc.com
