as you see backup takes longer than hour. so IDLETimeout greater than 60
(180 or 300) ought to help. Check the actlog for messages at the time node
reports lost session.
if no server initiated session closure and idletimeout does not help -
check your network for auto/half/full/10/100 settings or congestions
during the night.

Sometime i get more than one "ANS1809E Session is lost - Successful "
Sometime i get more than one "ANS1809E Session is lost - Successful "
before i get a reopen procedure failed.
I always get a " ANS1369W Session Rejected: The session was canceled by
the server administrator" after that.

I read somewhere that putting a higher number for the COMMTimeout ( 600
sec ) and IDLETimeout ( 60 mins ) can
resolve my problem..

But is't really all i can do ?  I've found nothing about SESSION Timeout..

How can I set my connexion ?

Can you help me ? Im a little green with TSM right now, but i try to
figure it all.  RTFM is my motto, but the boss here
don't seems to have the time I need to read it all ... If you can push me
on the right direction..


Thx
