Do you use LVM2 (or can you use it)? If so, make a snapshot and backup the
snapshot. 

You can hardly backup every file every time it's changed, that's not what
backups are for. You should inform your users about the backup policy _you_
are going to use on your system, tell them why you will do X backups per Y
days, and that if they want higher-rate backups they should use their own
method.
