Thanks for the response. Yes, dd is one way of achieving what I want - which is to allow rollbacks to earlier states - but I guess, if one's going to be slightly pedantic, it's more a cloning solution than a snapshot (and at this point I could just go with lvm snapshots). It's certainly a possibility but I am curious to know if there's anything out there which mirrors the simplicity and speed of the snapshot functionality in XCP. I'm guessing not yet...
