We have 2 backup Servers on site,
both are running server 2008 R2, same hardware, and have backup exec 2010 installed.
both are plugged into a gigabit switch,
but when the backups are running backup1 which is for staff runs at around 31mb/min but backup2 (students) runs at around 300mb/min both the staff and students servers are on our vSpere servers, Before we only had 1 backup server that ran both staff and student backups at around 300mb/min so has anyone any ideas on how to get it back? as we are compleatly stumped
You can try altering the way in which the data is being directed to the server.
if backup 1 is receiving data on nic1 @ 300mb/per min via a gb switch try putting backup 2 on a different switch so in effect you have 2 data streams. The other thing you can try is teaming nics together (assuming the server(s) have 2 or more nics (switch config would be required to combine ports). Of course there are other factors such as disk and network performance which can affect the throughput but i would try these before looking any further.
out of interest is the data going direct to internal data / scsi / sas drives or an icsci target ?
the servers are in house built, so they only have one network card at the moment, and sata drives in raid 5... the weird thing is even if backup2 is off or not using data backup1 is still running only at 35 mb/min :/
swap the network cables/ports over to eliminate any network issues
