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.

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
Compression level
This option is effective for Windows and Linux operating systems and bootable media.
The option defines the level of compression applied to the data being backed up.
The preset is: Normal.
The optimal data compression level depends on the type of data being backed up. For example, even
maximum compression will not significantly reduce the archive size if the archive contains essentially
compressed files, such as .jpg, .pdf or .mp3. However, formats such as .doc or .xls will be compressed
well.
