I used Areca backup in the past, nice tool.

To restore your whole backup archive you'll need the first full backup 
file and every delta you have produced afterwards.

I prefer using differential backups instead incremental/delta ones 
because it facilitates the restoration process (you only need two files). 
The drawback is that it takes more space.

Yes, is more eficient, but a complete restoration of the backed data will 
require that all of the small deltas to be there.
