rsnapshot is a perl script wrapper for rsync. Works *beautifully* to
provide hardlinked temporal snapshot repositories, I've used it
effectively for years.
dump/restore is also deprecated because it's reading the raw
fileystem, and modern Linux (such as CentOS 5.x) does a lot of paging.
So data that is still paged out yet, and not yet written to disk, is
not backed up correctly and likely to be corrupt. Definitely switch to
tar, or star if you need SELinux permissions backed up, to write to
disk or for temporal snapshots of your OS.
Rsync, unfortunately, has issues with SELinux restoration in my experience.
