The interesting thing here is that your backups ran correctly before the
upgrade. I am going to run a test on our old system to compare the
difference in time (networker 7.1.3).
My backup just spent 30 minutes appearing to do nothing. Then it started
to write to disk. If my 120,000 files took 30 mins then your ten million
files could take approx 20 hours.
Can you try a smaller volume specified in the saveset? I will let you
know how my test with 7.1.3 goes.

Stan/Mark,
Thanks for the responses.
We are running Networker nw_7_2_LGTpa69733.Build.6 Eval, which at the
time of installation I believe was the latest version plus a fix for a
portmapper vulnerability. Since we've added subsequent patches:
75442,72402,75831.
We have 3 NDMP clients the largest being 110GB, but with 10million
files!
Our Filer is a NetApp F810, running NDMP version 3, which is still
apparently supported.
This all worked fine until the Networker upgrade. Apparently 7.2 now
deals with NDMP backups in a modified way utilising disk as opposed to
memory, to increase backup performance! Our ...+AFw-nsr+AFw-tmp directory now
requires over 4GB of free space and also apparently only supports up to
15 levels (not sure if that's a new feature)
I'm fairly sure the nothing is happening, twice I've set the backup
running...checking late at night (were the data component was
completing) in the morning the group is still active, but nothing is
happening....so its been left for around 8 hours.
I noticed that when a backup is set running, before a backup rate is
indicated against a drive it shows 192KB, that is still the case.
In an attempt to secure to tape I've started using the Filers' 'dump'
command, although I haven't been able to perform a test restore.
Thanks
Nick

Are you running NetWorker 7.2.1? What kind of NAS are you working
with? I am running NetWorker 7.2.1 and NDMP backups work fine, as do
recovers. I did have a problem with a test I did of backing up NDMP
data to non-NDMP tape devices where the backup succeeded, but the
recover failed. This is with using a Mirapoint message store as the
NDMP client.
