Try going to the RedHat website. I'm sure if you make an account there you can get some good tools.

Use LVM and lvcreate snapshot on free VG space, mount snampshots on /mnt/mountpoint,
mount a storage device and cd /mnt/storagemountpoint/path/to/dir/archives.
Use tar to backup.

Piece of cake, easy as pie.
