I've being using zfs for the adv_file on my test box for a few months
now. I was using one of the nevada releases earlier, and now 06/06 - it
certainly works on sparc, I expect it would be the same with an x64,
there are a few weird messages when it fails to backup the filesystem
(eg it fails to read .nsr, but then gets nowhere anyway and exits that
saveset) so on observation at least it appears to work just fine. The
usual problem though is getting EMC to sign off that your config is
supported. While it may not be strictly necessary, I believe you can ask
for the hotfix for zfs backups and with that I believe EMC will be ok,
but better to wait for the x4500 to pop up on their HCL nontheless.
I'm planning on getting an X4500 too, they're not shipping until mid
september anyway, and 7.3.2 / 7.2.3 are rumoured to be released around
then.

Subject: [Networker] Using ZFS for a disk device?
I've been looking at Sun's new x4500 server, and (though unable to
aquire one anytime soon) made me think about ZFS and the adv_file
device.
I know NW cannot currently backup a ZFS partition; However, since it
also does not backup the contents of an adv_file device either, does
that allow us to use a large (multi-terabyte) ZFS device as part of the
Disk Backup Option?
I'm thinking this would hinge on the ability of a pre-6/06 Solaris app
to be able to do ordinary read/write to that partition, without worrying
about the new ACL subsystem. Also depends on what Solaris libraries
Networker is linking to I suppose (given recent discussion), though for
now let's assume a 7.2.x server install.
I'm definately curious if someone has tried this. It would be nice to
know fron a DR standpoint, so that I'd not have to worry about getting
another Veritas license bootstrapped during reconstruction.
Thanks in Advance,
