My own mediadb (and the rest of /nsr/res) has come along from 32-bit OS's into 
the 64-bit era as well.  I also have experience with the savegroup emails not 
always being correct.  When the amount of data crosses the 2TB limit, it is a 
crap shoot whether the data displayed in nsradmin's 'show session' will be 
correct or not.  I often get push back from my customers and I have to explain 
to them that their backups are too big (in that regard, I like this bug!) and 
because of that they will need to do an mminfo query to see the real size of 
their saveset.

I also opened an issue with EMC, and got my name added to the RFE for this 
problem, which is NW113348.  I don't know if EMC will ever have a real fix for 
it (other than the clean slate restart with running scanner on all your media 
volumes [shudder]).  However, eventually some bright programmer will stumble on 
the exact combination of what is doing it and be able to write a conversion 
program to read in the 32-bit /nsr/res constructs and write out the correct 
64-bit /nsr/res constructs.  Still, I'm not going to hold my breath waiting!   
It is yet another reason to keep individual save sets below 2TB...  Yeah, I 
know, that's not realistic anymore.

  This doesn't make sense because mminfo, and nsradmin's 'show session' knows 
the correct size as can be seen below. The problem seems to be with some 
variable defined as 'int' and not 'long int' in nsradmin and NMC.

AFAIK this is a known issue if you've upgraded a 32-bit mediadatabse
from an old networker to a newer 64-bit nw and mediadb.

I don't think there's any other way around it than making a complete new
64 bit backup server and then moving the data to it. That is use scanner
to populate the new media db (yes I know).

Hello all,

    I have this script which tries to dig some statistics from nsradmin's
session statistics. It works nicely for sessions smaller than 2Tb, but
breaks above that. I suspect that nsradmin does 32 bit counters. For
example:

[root@legato ~]# nsradmin
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.

76501 r=0MB/s size=841GB/971GB time=16205m ETA=5/23:43

    The size is reported correctly with nsradmin's session attribute:

[root@legato ~]# /usr/local/TAUSRC/Local/ToolBox/showsessions.pl|nl
       1    dayan-ng.tau.ac.il:root browsing

4431 GB of 5313 GB
       3    legato.tau.ac.il:cloning session saving to pool 'TAUDefault'
(JDF648)

   NMC is no better. It thinks that the size of this staging session is
1018Gb. I had this investigated under SR#44358972, but they claimed that
this was OK with 7.6.3HF and was related to NW138153. Networker is now
7.6.4.2.Build.1060, but the problem is still here.

   Does anyone knows which version has this corrected ?
