One of our goal is to have a `any-server` backup: A server cloning many
other and being able to replace other on the fly. Our backup strategy
is using rsync and the backup machine moves that to tape. The backup
machine can be use as a failover, manually.

Note that using heartbeat for example could easily be done to toggle vservers.

We have played with nbd (network block devices) with some success (good
performance as well), but never gone in production with that.
