The following table describes the different settings of the GeminiBackup plugin. Change the settings before starting the backup.

Setting Description
Directory for the files: Standard the directory /media/hdd is used to store the backups. With OK, it's possible to select a desired path for the bakups.
Name Changes the file name of the backup.
Factory reset Be careful with this setting. If enabled, on, the settings need to be set after flashing the backup. If disabled, off, the factory reset is not initiated.
Compression Choose the desired compression for the backup. The compression affects the backup speed and file size.
Debug Enable this setting, on, to see detailed information concerning the backup creation.
Directory for log file: Sets the path for the log file, geminibackup.log. Default path: /var/log.

Compressions compared

The following list gives an indication of the different compressions.

  1. Busybox xz: very fast (on internal SSD less than 15 seconds - size 275 MB), uncompressed
  2. xz (fast): same image, 120 seconds, size 76 MB
  3. xz (best): 180 seconds, size 73 MB
  4. gz (fast): ca. 30 seconds, size 105 MB
  5. gz (best): about 2 minutes, size 95 MB

If size doesn't matter, use the first setting for a fast backup. In case your storage capacity is limited, use the fourth setting, the backup is still fast and the size is reduced by +/-60%.

Create backup

After changing the settings, the backup is started with the green button save. The red button Log file displays the information about the backup on the TV.
