For what reason ever for our new Exchange environment our Exchange Admin team had reduced the number of volumes, increased their size, and had instead configured two databases and their log files per NTFS mount. (16 databases in 8 NTFS mounts on each DAG node of a total of 48 databases in the DAG).
But Data Protoector doesn't support this. Only one VSS Agents starts per volume. So it is being accessed twice with the same Volume GUID on VSS. VSS returns with error VSS_E_OBJECT_ALREADY_EXISTS. So only one of the two database ist backed up.
A change of the running Exchange environment is not a solution for our Exchange Admin team!
My workaround are two specifications for each DAG node: one for all first databases of all volumes, and a second for all second databases of all volumes.
My idea is, that Micro Focus investigates with Microsoft if such configuration is common for Exchange installations (that not backed up with Data Protoector).
In this case should Data Protector support such configuration.
Maybe with one VSS Agent per database instead per Volume ...?
