This option is effective only for Windows operating systems.
This option applies to disk-level backup. This option also applies to file-level backup when the file-level backup is performed by taking a snapshot. (The File-level backup snapshot option determines whether a snapshot will be taken during file-level backup).
The option determines whether to take snapshots of multiple volumes at the same time or one by one.
The preset is: Enable.
When this option is set to Enable, snapshots of all volumes being backed up will be created simultaneously. Use this option to create a time-consistent backup of data spanned across multiple volumes, for instance for an Oracle database.
When this option is set to Disable, 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.
