ZFS and ufsdump


Hello,

Quick question for you guys.

If I did a ufsdump of my machine; will the zfs mounts and data be there if I did a restore with the tape?

Also:

How can I recover from a "catastrophic" failure running zones on a zfs mount (meaning if all 4 discs fail on my T2000)? Would a restore from tape bring back everything? Assuming that I did a ufsdump?

zfs and zones are really new to me and I just need a quick rundown (ie not a post that says "read this" and it's a link to a 400+ page pdf). Some quick and dirty rundown of what i'll need. Thanks.

ufsdump is only for ufs, not zfs.
Use zfs send and zfs receive for your zfs backups.

Assuming you backup properly all your data somewhere, i.e. with zfs send, you'll be OK.
You can also consider using AVS: http://www.opensolaris.org/os/project/avs/
