If you can upgrade you client to 5.4.x or higher then use:
MEMORYEFFICIENT diskcachemethod
diskcachelocation y:\TSMCache

Note that the cache location may require a few GB of space.
We backup 8.2 million objects in 18 file systems without journaling (long 
story) on a 32bit 2003 server.  This is about a 12 hour run.

To speed up the backup you can also use:
include.fs C: memoryefficientbackup=no
This allows a file system to make a normal backup.

Once you have completed a backup with a 5.4 or higher client you will have a 
TSM.ini file that will help you decide which file systems can be backed up 
normally.

On a 64bit 2003 server we do 12.4 million without anything special. (Still no 
journaling) This is about a 10 hour run.

Subject: [ADSM-L] Another question about backing up a filesystem with a large 
number of files.

I have a filesystem on a windows server that has a very large
number of files in it.
I have been using journaling with some success until now. The
problem is that once journaling is turned off for whatever
reason, a full incremental backup is required before journaling
can be used again. Even with memoryefficientbackup set to yes
TSM runs out of memory if it is other than an initial backup.

I tried dividing up the filesystem with commands like:

dsmc incr "e:\blackboard\courses\a*" -subdir=yes
dsmc incr "e"\blackboard\courses\b*" -subdir=yes

but the backup seems to take forever for a single one of these
commands. I have dsm.opt set to exclude all domains.

My question is, if I delete or rename the old filespace and then
try these backups. I know that the first time they will simply
backup everything. Will they set things up on the TSM server so
that subsequent backups will work against the divided filespaces
and thus run a little quicker?

TSM server is 5.3.1.3 on AIX
TSM client is 5.3.5.6
Windows is Server 2003

Thanks in advance.
