Re: DAOS, and many objects.

[Chris Whisonant <chris.whisonant@xxxxxxxxx>]

I, personally, would advise against trying to do anything with virtual
optical and DAOS. The good thing is that you don't have to use ANY downtime
to backup DAOS objects, so you're just looking at time here.

As far as restoring goes, in general you'll hopefully never going to
restore the full DAOS directory. But if you have a user who deleted
something and it was the only instance of that attachment in the DAOS
repository, it's going to be a whole lot faster and easier to just restore
that one NLO. You just run a command to list the missing NLO's for the db
and then restore the missing object(s).

tell daosmgr listnlo -o mymailobjects.txt MISSING mymail.nsf
