[CentOS] Centos backup tools

Hi all!

I'm building a raid box to use for backups, connectivity will be either
USB3 or esata.

Looking for suggestions on backup software I can use.

I know there's rsync, which may be a good solution. I also find backupPC
at epel, backintime also at epel, kbackup.

DejaDup looks interesting, but none of the repos I'm set up to use
shows it being available.

some small details: I plan to use this to keep backups of my centos
desktop, which has two 320GB drives in linux RAID-1. The backup box will
have two 1TB drives, also in RAID-1. It will be a two drive enclosure
with PS and cooling, with USB3 or esata, but not networking.

I was thinking that it would be nice to have a full backup followed by
a set of incrementals, and software that allows access to the state of
the system for any specific date (similar to a source control system),
but it may be that nothing free and/or uncomplicated will offer such
a feature.

But, as I always say, "suggestions welcomed!"
