rsnapshot de-duplicate files not blocks. If you backup files from your VM
you can de-duplicate. If you want to backup whole VM images of course you
need a tool working on physical blocks.

rsnapshot use hard links on the backup filesystem. I encrypt this
filesystem. Integrity is the same for all backup systems. Doing 2 backups
on remote places cover this.
