Try rsnapshot: its fast (uses rsync to make backups) and lets you have
more than just the last backup version available. I have it set to make
daily and keep 4 weekly backups, which means it keeps 7 daily backups,
combining the dailys every week to make a new backup, which is kept for a
month. as each 'backup' is simply a list of pointers to timestamped file
copies, the rsnapshot backup set seems to be about twice the size of a
single rsync backup and making the weekly snapshot takes twice as long to
make as the daily one, i.e. 8 minutes compared with 4 minutes for the
daily run and the complete set is 183GB.

For comparison, when I previously used compressed gzip daily backups,
these took 3.5 hours and I could only fit 4 daily backups on a 320 GB
disk.
