Normally the idea is that you do full backups every so often, and
incremental more often. Being incremental it takes less disk space (i.e.
it's sort of like just storing 'diff filea fileb').


The advantages of incremental are speed and using less resources (at
least from a storage point of view).

The draw back of incremental backups is that you would normally need to
restore from a full backup, and then restore each incremental backup in
order to get to $last_known_state_before_disaster.



Try looking at something like rdiff-backup, it's quite friendly, and
easy to use.

David.
