we are using backup exec 11d to backup data from our servers using remote agent.
backup exec is installed one windows 2003 server (tape drive is connected to it), and we have an esx 3.5 server with several virtual machines, and one other windows server is also backed up with backup exec remote agent.
evern after we virtualized our file server, we still use the remote agent to backup the data off of it, just as before we virtualized it.
we have been doing this for 6 to 8 months without any major issues.
what I am running into now is that the backup has gone from taken 12 hours to 36.
I have narrowed it down to the one particular virtual server, our file server. the other virtual server still backs up at 280 to 300 mb per minute, where the file server is doing less than half that.
I am watching it now, and it started at over 200 mb per minute, and it looks like it drops a meg every minute or so, down to 39 mb per minute now.
why would one virtual server backup so much slower than the other?
what should I look at?
