VSS snapshot volume requirements
The Microsoft VSS framework supports as many as 64 volumes in a VSS snapshot. When you create a dataset or perform an on-demand backup, do not include more than 64 volumes. If you include more than 64 volumes in a snapshot, then the backup fails and the Avamar event log lists the following error:
VSS_E_MAXIMUM_NUMBER_OF_VOLUMES_REACHED.
The VSS framework also limits the number of shadow copies to 64 per volume. If the number of shadow copies in a volume exceeds 64, then the backup fails and the Avamar event log lists the following error:
VSS_E_MAXIMUM_NUMBER_OF_SNAPSHOTS_REACHED.
