Yes, but the long backup time is because of the time it takes the TSM client to query the TSM database for backup file candidates and not due to the actual movement of files from the client to the TSM server. So how pulling from 10 separate drives increase the query speed.
For instance it takes hours and GB of memory on my client for the client to query the TSM server for file info for 15 million files even though the actual backup will end up being 11,000 files consisting of 300mb. And the backup take over 17+ hours to complete. This is running from a GigE connection with my client with 4 cpus and 6GB of memory although it is Win2k. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Stapleton, Mark Sent: Thursday, June 16, 2005 12:53 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: 15,000,000 + files on one directory backup No, because you're pulling data off of 10 separate physical drives.
