Data Deduplication

Virtual Machine disk images deduplication
Zero free blocks of the filesystem within the disk image
Windows: use SDelete:
C:\sdelete -c
Under linux:
$ dd if=/dev/zero of=/deletemesoon; rm /deletemesoon
This method will not work if the disk image is a sparse file. It will fill all the holes.
Deduplicate the filesystem which the disk image is on
- Sparsify.
- Relink.
