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.

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.
