[H-GEN] Linux Block Level Backups

[Stephen Thorne]

This is a recipe that may work for you:
- ZFS storage array.
- Store VM disk images on the storage server via NFS.
- Snapshot the ZFS array every N minutes.
- Use zfs send to send incremental updates over the network for backup
periodically.

ShadowProtect can take snapshots at up to 15 minutely incrementals and replicate these offsite (as well as to local storage).
