I really don't know much about ZFS, but I do know about disks (I work on SAS
device drivers for AIX and deal with lots of disks); and I doubt that any
filesystem is going to be immune to sudden power failures when writing to a
disk. At least I wouldn't trust them. If you care about the integrity of your
data, I would reconsider your plans about the UPS.
