Slow backup job rate
We have a Netapp device that directly connected to tape via ISCSI and both has a 10 GBlinks. We also set up Exagrid device which also has 10 GB links. Our backup infrastructure is to backup snapshot of volume on netapp filer using B2D (exagrid) then duplicate to tape.
From the above configuration, we run a test backup of snapshot which has a total size of 1TB of data at first, job rate took 4GB/min then after hours of running job rate was continues to drop from 4GB/min to 102 MB/min. Anyone have suggestion on how are we resolve this is greatly much appreciated. Thanks.
