Here's a weird one. My DBAs need a MS SQL DB restored, and they need it
done as a "No Recover" sort of restore. That's (apparently) a special kind
of MS SQL restore, which would allow them to replay the transaction logs,
and bring the DB back to the point in time they want.
So I go to the client (a SQL 2008 cluster, so it's a virtual client), fire
up the SQL Module GUI, choose a recover (copy), and browse back to the
date I want (2012-06-19), choose my DB, see that it has the right size for
that date (567G - it's a big one), and change the properties to choose a
"No Recover" restore, and change the destination path so it goes to a new
folder. All well and good, and just like the manual says.
But what I get back is the database as of 2012-06-20 (i.e, the next day).
When my guys open the restored DB, they say it reports that it was backed
up 2012-06-19, and at the time of the backup of 2012-06-20.
I did both an mminfo and and nsrinfo, and I see my file as of 2012-06-19.
So how come I get the right file as a "normal" recovery, and do *not* get
the right file when I choose the same file (same browse time, choosing the
same file), but change the recover option from "normal" to "no recover"?
I had 2 different Tech Support folks trying to help me last night. Since
we're desperate for *something*, I did a "normal" recovery overnight, so
my guys at least have something (you can't replay transaction logs against
a "normal" recovery, they tell me. But at least they have all the records,
before they wrongly deleted them on 2012-06-20). I did indeed get 567G.
And when the DBAs open this file, it does indeed say backed up 2012-06-19
22:15PM.
Note that these are FULL backups, not incremental.

So you see I have the backup. But the "no recover" doesn't give me this,
but the "normal" recovery does. The "no recover" gives me this:
volume client name lvl total save
time date ss completed ssflags

That's what the NW log shows as being restored - 174G. And that's the date
and time the recovered DB shows - 2012-06-20 10:14PM. Even tho I asked for
the file for the 19th ...
And I'm still waiting for Tech Support to call me back this morning;
apparently they have a large number of Sev 1 calls. Meanwhile, we're
sitting here not really able to do what we need to do with this DB.
Anybody have any ideas?
