If we could get some assistance in determining whether Veeam is in fact the culprit (at least for the dedupe ratio) that may assist.
My colleague was told by Veeam support that we should not use backup copy jobs on our dedupe appliance, because they use a transform process.
We're currently running backup copies with the same appliance as source and destination of the copy, which I realize is going to impact performance.

If applicable, use some local disks on backup server as a target for backup job (short retention), and copy data afterwards to the said dedupe appliance via backup copy job (longer retention).
