i do send the tapes offline. The idea of sending onto another system seems
an excellent idea but i would still need to send them to tape. if i tar or
dump the replicated filesystems this will chew up a lot of space since my
filesystems are almost 900GB in total

hello team
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.
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.
