VSS_E_MAXIMUM_NUMBER_OF_VOLUMES_REACHED

VSS_E_MAXIMUM_NUMBER_OF_VOLUMES_REACHED means that the current shadow copy operation already contains as many volumes as VSS permits in a single snapshot set. Microsoft documents a maximum of 64 shadow-copied volumes in one set.

What to do

Split the backup into multiple snapshot sets when the requested volume count exceeds the limit.
Review whether all selected volumes are required for application consistency.
Do not add volumes after the limit is reached and assume that the provider will include them implicitly.

Microsoft: snapshot-set volume limit
