I am restoring 2-drives (F: and G:)  with 27M and 22M objects and 900G and
700G, respectively.  Since the F: was going to be so problematic, I
decided to start the G: last night at 11:30pm since I can run
NQR/unattended.  So far as of this writing, it has restored 15M/250GB.

Not sure if the PIT will be much good for the F: drive since it will have
to select EVERYTHING for the restore no matter what PIT I go to (which
looks to be at least 15-days ago since that is when the F: backups started
registering "unreadable/corrupt" files. I will try PIT once I finish the
G: volume.

OS is W2K3SP2 Enterprise Edition.

Zoltan,
Have you attempted a Point in Time restore from command line?
That might help with the number of inactive files you are experiencing.
If that is not an option, you may have to go a couple directories at a
time.

I have only had experience restoring up to 9M files and the one time I did
it used PIT and worked fine, turned maxmp up to 4. It certainly took a
while. But it did complete.

What OS are you using on the client ?


Duane

Trying to restore a LARGE Windows server.  Over 40M objects.  Client is
6.1

As you can imagine, we have had to use the journal as well as
MEMORYEFFICIENT to perform backups.

If I read correctly, MEMORYEFFICIENT is ONLY for backups.  Obviously the
journal is of no value since the restore is to a new machine/location.

The other issue gumming up the works is that the backups have been failing
(drive array problems/corruption) and thus TSM has marked almost
everything
as "inactive".  A first, NQR restore (just selected the drive) attempt
only
restored 90GB (of 600G+) before "finishing successfully".  But when I
choose to pick inactive as well as active, the NQR is disabled.

The server transfers down 1GB of metadata before the client chokes on
"insufficient memory".

So, how am I supposed to restore this many objects, besides picking one
directory at a time, which is not to say that some directories are large
enough to also cause a "not enough memory" situation?

Suggestions on how to handle this?
