Hi,
Disable the back-up of security info and split your back-up into
multiple domains/over multiple nodes. Also, you don't want to use memory
eff. Back-ups and resourceutil will only go up to 10.

Subject: Backup taking too long
I am backing up a large number of files and directories located on a
Network Appliance. I am using a Windows 2000 client to do this. It is
taking over 40 hours to do the backup. I also run out of memory at
times (ANS1028S). Journaling worked great when the files were on a
Windows system, but journaling works only on a local file system. I
don't think I can use NDMP because the tape library is connected only to
the Tivoli server. Most of the time (and memory) is spent determining
what files should be backed up. There are over 1 million directories.
Total number of objects inspected: 7,819,693 Total number of objects
backed up: 260,984
Total number of bytes transferred: 36.22 GB
Data transfer time: 4,579.15 sec
Elapsed processing time: 40:10:58
There are about 36 "root" directories so I could configure the Network
Appliance to have 36 shares and back up each separately if that would
help. I think this would help with the memory problem. I would
probably need to run multiple backups simultaneously though.
I have added the following to the dsm.opt file
RESOURceutilization 14
MEMORYEFFICIENTBACKUP yes
Any suggestions on how to speed the backup up?
Windows 2000 SP2 with 512 Meg of Memory
Client Version 5, Release 1, Level 7.0
Server Version 5, Release 1, Level 9.0
