Hardisks are cheap, so a couple of lines of shell script on the backup server 
can make sure that you have several complete copies of the backup.

Here is what I do:

For backup of sites, users, MySQL an DNS I still use RaQbackup.sh, which ftp's 
the data to the backup server on a daily basis. 

Additionally I Rsync data on a daily basis from all my developement servers to 
the backup server. On the backup server I daily run a script from a cronjob 
which copies the entire backup directory to another partition on another 
hardisk:

#!/bin/bash
rm -Rf /data/devel.bak2
mv /data/devel.bak /data/devel.bak2
mkdir /data/devel.bak
cp -R /backup/devel/ /data/devel.bak/

So in essence I then have three days worth of complete backups:

/backup/devel/      (complete backup from today)
/data/devel.bak/    (complete from yesterday)
/data/devel.bak2/  (complete from day before yesterday)
