A core info is missing : how did you do the recover ?
using ssid recover or browsing client file index ?

Another important think to take care of is tape multiplexing
during backup : How more multiplexed is the tape block, how 
more tape blocks have to be processed for extracting data.
In other words, Backup Rule #1 : fast backup, slow recover. 

You also have a look at which device mounted the volume for
recovery. Maybe did you recover across the lan ....

Subject: [Networker] Networker 7.3.3 Restores Slow

Greetings, In the past I've used Networker backups to restore to a new file 
system for migration reasons. Helps to stay off of the current one plus 
tested the backup (and restore) capabilities. I've done this for the past 
couple of years and was pleased with the performance of the restore 
operations (both directed recover and saveset recover).

About 2 weeks ago, I made a fresh full backup of a 2TB file system (after 
splitting a 4.7TB into 2 chunks).

Last week I started the restore to some new space of this 2TB and it has 
been taking "forever" to get the data off of the tapes.

When I did the backup, I was at 7.3.2 Junbo (399). A couple of weeks ago, I 
upgrade to 7.3.3.

Side Note: Last year when I started these type of migrations and tried the 
Linux "cp -a source-dir target-dir/." I would get the "max arguement" error 
message which is why I went to the NW restore option. Now the "cp -a" is 
working on these directories with 100K - 150K small files in them.

So as anyone done any massive restores with 7.3.3 and noticed any dramatic 
performance hits?

Thanks,
Randy
