Ed:

When you say you want to split a Solaris mirror is this using Sun's
DiskSuite, LVM or whatever they call it now?

We use Veritas Volume Manager on our Solaris systems. If you detach a
plex and back that up you will get data that is current to the time of
the detachment. (You would have to backup the block device due to the
state of the plex with the kernel.) When you reattach the plex VxVM will
re-silver the just-attached plex and make the data current. You could
try an incremental, but I am in league with your Solaris admin. I
believe you will need to take a full and then incrementals after. I am
ASS-U-ME'ing a lot too.

Subject: [Veritas-bu] Solaris split-mirror backups

Quicky question since I'm not a Solaris expert...

Can I split a mirror on Solaris, back up the mirror member, and then do
an incremental copy of the changed blocks when re-establishing the
mirror?  My Solaris admin is saying that I need to do a full mirror copy
and that's going to be painful...

Thanks,
        .../Ed
