[zfs-discuss] flar and tar the best way to backup S10 ZFS only?

I'm persuading a customer that when he goes to S10 he should use ZFS
for everything. We only have one M3000 and a J4200 connected
to it. We are not
talking about a massive site here with a SAN etc. The M3000 is their
"mainframe". His RTO and RPO are both about 12 hours, his business gets
difficult without the server but does not die horribly.
He currently uses ufsdump to tape each night which is
sent off site. However "ufsrestore -i" has saved is bacon in the past
and does not want to loose this "functionality".
A couple of questions.
flar seems to work with ZFS quite well and will backup the whole root
pool flar(1M)
This seems to be the best way to get the equivalent of ufsrestore -r
and a great way to recover in a DR event:-

My Questions...
Q: Is there the equivalent of ufsretore -i with flar? (which
seems to be an ugly shell script around cpio or pax)
Q: Therefore should I have a tar of the root pool as well?
Q: There is no reason I cannot use flar on the other non root pools?
Q: Or is tar better for the non root pools?
We will have LOTS of disk space, his whole working dataset will easily
fit onto an LTO4, so can anybody think of good a reason why you would
not flar the root pool into another pool and then just tar off this
pool each night to tape? In fact we will have so much disk space
(compared to now) I expect we will will be able to keep most backups
on-line for quite some time.
Discuss :-)

flar is mostly a wrapper for cpio, integrated with the installer

With the cost of tapes, drives, and off-site storage service (unless
its stored at the owners home), you could probably co-locate a server
with fast internet connectivity, a bundle of local storage, and just
ZFS snapshot your relevant pools to that server.
I second the recommendation of Amanda from Richard as well though,
pretty flexible solution. And it can backup much more than just local
ZFS snapshots if that would be a benefit to you as well.
