--multi_volume_snapshot={true|false}
This parameter is effective only for Windows operating systems.
This parameter is used with the backup disk command. This parameter is also used with the backup file command when the --snapshot parameter is specified.
The parameter determines whether to take snapshots of multiple volumes at the same time or one by one.
If the value is true or if the parameter is not specified, snapshots of all volumes being backed up will be created simultaneously. Use this parameter to create a time-consistent backup of data spanned across multiple volumes, for instance for an Oracle database.
If the parameter value is false, the volumes' snapshots will be taken one after the other. As a result, if the data spans across several volumes, the resulting backup may be not consistent.
