First, I will assume that you are @ SP5 for this NW6 box?!??
...and your BKUPEXEC.NLM is version 9.10 dated Octobet 8, 2004
When the server is being backed up how is the server utiliazation???
If this server is using traditional volumes... are the long term cache hits listed in the console monitor over 90%? If not, more memory may be necessary..
There are a lot of possibilities here but lets assume that the server is pathced, not being too stressed (whatever that means),well connected, with plenty of memory, and the volumes are on a good disk subsystem (SCSI2 or better & RAID)
...Assuming all that...you might be helped out to know that Novell has been regularly releasing TSAFS updates since the last version released with July's 2004 SP5 for NW6 (and I wouldn't be surprised if this is the last SP for NW6)
Unfortunately, these are not easily located in the normal patch download area on the Novell support site because Novell considers them to be BETA. If you want to try a newer TSAFS (at your own risk, of course) go here:
http://support.novell.com/filefinder/
...and search on TSAFS. The latest BETA version is tsa5up17.exe. BTW I have been running a BETA from October on MY NW6.5sp2 box since October with good results
Hope this helps...but there are a lot of possibilites
