Another way to do (I do it actually)

Is to get a drive with ext3 partition for example
Create a directory for your backup

and use Rsync to copy any file with differential feature.

=46irst time could take a long time, next time are very fast.

To backup everythink on the system, I run the single use mode,
It kill all the application runned ... so after, I mount bind root fs and o=
ver=20
sub fs in tmp dir, mount my backup dir in another tmp dir
and run mirror with rsync

=46ast, excellent, could easyly be migrate on another kind of server, or co=
uld=20
restore only some filesystem.

It's good !

Good luck
