Hello,
My setup is DPM 2016 VM running on Server 2016 and Server 2016 H-V host. The host also hold the storage VHDX files in storage spaces.
I can backup H-V VMs incredibly fast. For instance, one protection group of ~20 servers @3TB of data finished in about 20 hours. All of these VMs reside in my SAN (CSV connected)
Now I'm attempting to backup 2 large file servers. 1 is 2008 R2 physical with about 1.3 TB of data that resides on the SAN (iscsi connected). The second is a 2012 R2 VM but the data is also connected over iscsi to my SAN. This is the same SAN that my VMs use.
The backup of the servers is PAINFULLY slow. For instance, the 2012 R2 file server backup is 2 hours into it, and has backed up 6GB. I've performed copy jobs between these servers and they all go much faster. NOT blazingly fast, but average about 400 Mbps. -Edit- I should add that the copy job of SMALL files is about 400Mbps. The copy of LARGE files is easily 800Mbps. This is using Gb nics and during production hours (other contention is possible). The point is, it behaves as expected, outside of DPM.
Any ideas? With this performance, DPM is DOA.
Thx,
DML
