I use rsnapshot and think it is great. I have also used snapback2 which is a similar program but does not seem to have a very active user base. Some of the nice features of rsnapshot are:

1. Incremental backups, only modified files take up extra space for each backup
2. hourly,daily,weekly,monthly backup rotations
3. easy to maintain and modify
4. unlimited number of network clients can be backed up by single server
5. active mailing list if you have any questions
6. uses rsync as backend transport layer, which makes it very speedy

There is one issue that I ran into. If you are going to backup networked clients with a cron job, rsnapshot does not correctly handle if the client is off line for an extended amount of time. I wrote a small shell script to overcome this limitation. In my setup, each client has its own configuration file in /etc/rsnapshot/ in the format "hostname.conf".


for FILE in /etc/rsnapshot/*; do
   HOST=$(basename $FILE | cut -f 1 -d '.')
   if $(ssh $HOST true &> /dev/null); then
       rsnapshot -c $FILE $RSNAPSHOT_MODE
   fi
done
