you need to clone a filesystem per guest because ZFS can only rollback full
filesystems, not invidual files. your VM solution may have finer tuned
controlls for its own snapshots but those are don't use ZFS' abililities.

the act of deleting files in UFS simply does a few accounting changes to the
filesystem thus has no affect on the blocks in ZFS volume, and in some cases
could actually make the zvol space grow. The only possible way to have ZFS
hot spares to the system should
one fail. If you are truly paranoid, 3-way mirror can be used. then you can
loose 2 disks without a loss of data.
Spread disks across multiple controllers, and get disks from different
companies and different lots to less the likely hood of getting hit by a bad
batch takin
Yes send and receive will do the job. see zfs manpage for details.
