Hey there -
I was just wondering... Why is Veeam unable to read from multiple disk sources of a single VM while restoring, or during backup copies? It seems to be able to write to multiple files/volumes just fine during a backup job (for any given VM).
I have some fairly large VM's that have multiple volumes, and my primary backup device is a dedupe appliance (HPE StoreOnce), and this is a major drawback when restoring large VM's with multiple volumes, as well as with Backup Copy Jobs. I'm struggling to restore/copy single large VM's within a reasonable amount of time, and in one particular case, it's practically impossible.
When a job has multiple VM's, Veeam seems to have no issue reading from at least one volume/file from each VM's backup, which substantially improves the overall restore speed of all VM's in the job, but my issue is not with performance on a large number of VM's, just with the speed of many large volumes that are part of one VM.
HPE StoreOnce performs best when multiple streams are established for read/write, but it doesn't seem I'm able to take advantage of this using Veeam in this scenario, which is a bummer, and starting to become an operational issue.
