Compression

A backup file can be compressed. You can select the different compression level for a backup archive:

  • None - data will be copied without any compression, which may significantly increase the backup file size.
  • Normal - recommended data compression level.
  • Medium - takes more time to create compressed backup image file.
  • High - takes a long time to create a backup but the generated image file may be much smaller than other levels.

Note:The size of generated image file may not significantly decrease even though the High compression level is selected. That is because some kinds of files are essentially compressed, such as .jpg, .pdf or .mp3.
