I'd also add that unless you are sending tapes off-site, having a
snapshots on a seconds system can save you a lot of incremental backups.

i have an issue with my ZFS system, i have 5 file systems and i need to take
a daily backup of these onto tape. how best do you think i should do these?
the smallest filesystem is about 50GB
here is what i have been doing i take snapshots of the 5 file systems, i zfs
send these into a directory gzip the the files and then tar them onto tape.
this takes a considerable amount of time.
my question is there a faster and better way of doing this?
So you zfs send to a file and save the file to tape?
Personally, I use zfs send and zfs receive to replicate the data to
a second system, and then simply tar the replicated file system
to tape. That way I'm not dependent on zfs to get the data back
(and can get individual files/directories back if necessary, which
it often is). And you have the ability to slot that copy of the data
instantly into service if the primary copy fails.
