I have backup data for all Windows servers on FILE primary storage pool - so
there is no problem reading files for the both 2003 and 2008 servers.
I know about big number of files in SYSTEM STATE for 2008, but it I definitely
not a reason of bad performance. For example, 2003 server has total 72,000
files and 22GB - 2008 server has total 230,000 files and 47GB (data is
compressed).
This difference can lead to longer export for 2008 at least 3 times due to
different amount of data with the same speed 10-20MB/s, but in real live I have
speed 1MB/s and huge difference in export time.
I am using TSM Client 6.2.4.7 on the both 2003 and 2008 servers - the latest
officially supported version for TSM Server 5.5.6.

64 bit node
Hi Grigori,
Know that system state contains many more files in Win2k8 than in Win2k3 (10
times).
How are the data organised on medias within the storage pools ?
Which TSM version are you using for those Win2k8 clients ? 6.2 that allows for
incremental backup of system state ?
Regards,
Erwann
