B2D jobs from the NAS are running at less than 150MB/min while every other job from other sources are running 1100MB/min +. Is there anything I should be configuring a different way to help increase the speed of the backup jobs?
All B2D jobs store their data on the same NAS share that is having the speed issue serving data.
Using a different B2D host to store the virtual tapes has the same speed issues when the data comes from the CIFS shares.
A backup job from a Windows server in a building over a 100Mbps WAN link several miles away is able to run at 300% of the speed the NAS job is running at on the local 1Gbps network.
