Thanks for your comments. I see that Martii you do almost exactly as I do. It's good to know it works as intended.

I've also tried sdelete on a small VM and the backup has dropped from 5.6Gb to 3.4Gb on a 30Gb partition disk. Quite impressive.

I've just also found "zerofree". A linux utility I didn't know about that zeros free space on ext2/3 filesystems. The device has to be unmounted though.

Thanks again.

Aleix.
