People have already suggested rsync and rdiff-backup; there's also
rsnapshot which is built on top of rsync.
Another option could be mdadm if your RAID1 is already an mdadm array.
You can add your USB drive to the array, wait for it to rebuild, then
remove it from the array. I'd be wary of backing up an SQL database in
that way, but I'd be wary of using rsync, dump, or tar too, so be sure
to take a real backup (e.g., mysqldump, pg_dump) of your database first.
