Dear all,

We are experiencing system problems with a large NT4 fileserver (500 Gb
storage, 2 * P3 Xeon 550, 512 Gb RAM), the system has been found hanging the
last three mornings & had to be cold restarted.  We are running Netbackup
3.4 patch level 3 on the Solaris servers & patch level 1 on the NT clients.

Fingers are being pointed at OTM (because yesterday when the problem
occurred the winnt system drive was found to have filled up, & an old OTM
cache file was found on it).

I have seen on this list that other people have had issues with OTM.  I know
it is a pain to configure and doesn't seem to work very well, can it cause
system problems?

I have also seen that people have turned OTM off.  What are the effects of
this - I would assume that all open files would therefore not be backed up
and we would get lots of 1 return codes.

When OTM is working correctly I does it create cache files & delete after
use?  Can it create multiple?  Why would it leave them lying around?

Any help appreciated ... thanks, Phil

Subject: [Veritas-bu] Catalog backup question (NetBackup Datacenter 3.4
UNIX)


I need a way to find out how much data is actually being written to our
catalog tape.  I used the following:

bpbackupdb -v

and looked at the /usr/openv/netbackup/logs/admin/log.<date> file

It did not have the total number of bytes written to the tape anywhere in
the output.  I'd like to know how close I'm getting to filling my catalog
tape.

Is there an easy way to determine this information, or do I have to just
guess that since the data in the 

/usr/openv/netbackup/db 

directory is mostly text that it will get at least a 2:1 compression
(probably closer to 4:1) and use that as a guide for how much will fit on my
DLT7000 tapes?  Since the hardware compression will get about 70GB of
compressed data on a tape, what's the realistic amount to expect that will
fit on the tape?  Would I have to worry if my db directory is about 50GB?
100GB?

thanks,

--stuart
