Hi Bruce!
Thank you for your reply!
The total amount of files is about 600.000 files, so journaling is maybe a
bit overdone. The problem is not the amount of files, but the time in takes
to scan them. It MUCH slower than on other Windows NT clients.
Kindest regards,

You might want to consider journal backups! Depending on how many files
change on a daily basis.

Hi *SM-ers!
TSM server 4.2.2.0, TSM client 4.2.2.0 on Windows NT SP4.
I have got a strange problem with one of my Windows NT clients. The backup
cycle runs for almost 24 hours. The thing is that the actual backup runs
fine:

You can see that backing op an almost 4 Mb. file takes about 2 seconds,
which is ok. But the file scanning runs at an excruciating low speed:

Scanning 6000 files takes 16 minutes!!!
Has anybody seen this before? I really don't know how to 'debug' this...
Thanks in advance for any reply!!! Kindest regards, Eric van Loon KLM Royal
