For those of you doing ZFS, what do you use to back up the data after a

haven't figured out how to replace ufsdump in our backup strategy.
There are other commercial backup solutions however we were
already a NetBackup shop. So we simply set our backups to run
against the mail@yesterday path. A locally-written script managing
the snapshot process rolls @yesterday into a date-coded format
e.g. mail@20100214 before doing the new @yesterday snapshot.
It also destroys the 15th snapshot.
The snapshot path is a "real" filesystem that
is traversible it's just read-only. So other backup
solutions like Amanda, star, etc. should work fine.
I expect everything except ufsdump should work
fine and really, doing backups on a hot filesystem with
as much activity as Cyrus seems pretty iffy anyhow.
Yeah, unfortunately our enterprise backup solution is TSM, which is good
for just about everything but Cyrus. (It keeps a database with an entry
for every single file, which with Cyrus's tens of millions of files, really
doesn't work well.)
Would be nice if the TSM UNIX clients supported journalling.
We'll probably end up doing something with tar and either TSM or our new
VTL infrastructure, but I was hoping someone had some prebuilt scripts or
something cool that would take care of it.
