3.3.1.5 File-level backup snapshot
This option is effective only for file-level backup in Windows and Linux operating systems.
This option defines whether to back up files one by one or by taking an instant data snapshot.
Note: Files that are stored on network shares are always backed up one by one.
The preset is: Create snapshot if it is possible.
Select one of the following:
 Always create a snapshot
The snapshot enables backing up of all files including files opened for exclusive access. The files
will be backed up at the same point in time. Choose this setting only if these factors are critical,
that is, backing up files without a snapshot does not make sense. To use a snapshot, the backup
plan has to run under the account with the Administrator or Backup Operator privileges. If a
snapshot cannot be taken, the backup will fail.
 Create a snapshot if it is possible
Back up files directly if taking a snapshot is not possible.
 Do not create a snapshot
Always back up files directly. Administrator or Backup Operator privileges are not required.
Trying to back up files that are opened for exclusive access will result in a read error. Files in the
backup may be not time-consistent.
3.3.1.6 Multi-volume snapshot
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 (p. 58) 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.
