The Part of the raid is used for Backuppc, part for rsync. The rsync data
is stored with zfs set compression=lzj. Whole pool is backuped every month
to the TAPE. If zfs fails at least I will have one working copy from
TAPE(worst case a month old).
Second issue probably I should distribute backups on different zfs/hosts.
Looks like on parallel IO time ZFS is CPU hungry.
