Option in a restore from differencial (-D) backup to remove files deleted following full backup

[mread]

Please include an enhancement to the restore function to remove restored files deleted from the original media between reference "full backup" and corresponding "differential backup (-D)".

After a few restores from a "differential" and "full" backup set, one can end up with a whole bunch of previously deleted material that takes up increasing amounts of space.

I realise this adds to the complexity of the "differential" process, probably requiring a comparison between file system and files backed up in the reference "full" backup and a listing of differences - rather than simply backing up all files with a modification date after the "full" backup, but it would improve the functionality of the "differential" backup/restore process hugely.

Thanks.
