Hi Akash
                We have found if you are using 100mb network for example
you have to ensure that all interfaces are set to the same speed etc eg:

Host 100mb/Full switch port 100mb/Full and backup server 100mb/Full

Hope this helps 
Cheers Mark

Subject: Backup

Hi all,

I am in very strange situation where my Oracle backup sometimes
completes in
1 hour and sometimes it took only 16 minutes for same data.

On scrutinising the logs, it has been observed that it's the matter of
network performance. Sometimes I am getting a speed of 1206kb/ps (data
took
1 hour to backed up) and at 4506kb/ps completes in 16 minutes.

I am assuming this is the network issue and to be checked by networking
guys.

Does anyone have faces this problem or any ideas about the same?

AIX - 4.3.3.11
Data - Oracle Files
Backup Software : TSM
