here is a script from LINUX HACKS -
it will create a local mirror (in this case different HD) of the live
file system, and at the same time, create incremental backups of the
changes made - it only takes up
original-storage-size + diff(changes-to-files) .. I have overa year of
incremental backups on a 40GB drive mirroring about 20GB of data
umount /mnt/mirror
mount /dev/hdd1 /mnt/mirror
df -h;echo
cd /mnt/mirror
rm -rf /mnt/mirror/`date | awk '{print $2$3$6}'`
# copy current backup to a dated backup
# cp -al creates linked copies, in essence making incremental backups when
# the original file changes
cp -al /mnt/mirror/local /mnt/mirror/`date | awk '{print $2$3$6}'`;echo
# rsyn the active file system to the local mirror
rsync -ru --stats --delete /samba/* /mnt/mirror/local/;echo
