I used TSMCLEAN on 2 different NT 4 server clients. The only issue I had was users complaining of the performance hit because I ran it during the work day. It basically impacts the system the same as a real backup would, except I had about 20 times the normal backup amount because of all the corrupted files. I read all the instructions and readmes several times before I attempted anything. =========================================== John Monahan Network Team Coordinator Liberty Diversified Industries (763) 536-6677 =========================================== Gunnar Uhr <[EMAIL PROTECTED]> Sent by: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> 03/14/01 07:00 AM Please respond to gunnar.uhr To: [EMAIL PROTECTED] cc: Subject: Experiences from Client-Patch 4.1.2.12 ( and on Ms Clusterserver ) ? Hello everybody. I'm having a number of NT-servers (clients) and Win2000 Servers that I guess would be best to install/run this patch on. Does anybody have any experiences of using the Client-Patch 4.1.2.12 on Win32 ? I also have a few Ms Clusterservers ( NT 4.0 ) that I also have to do this on. Are there anyone of You that has done this - or has any ideas according to this ? Are there anything "special" to concider when running the TSMCLEAN. I would very much like it to be OK "on the first try" - this time ;-) Regards Gunnar -- **************************************************************** Gunnar Uhr IT-Service KAROLINSKA HOSPITAL STOCKHOLM SWEDEN e-mail [EMAIL PROTECTED]
