   Table 1 Parameter description

   Parameter	Description
   Automated Backup	After automated backup is enabled, the system will back up table data based on the preset backup policy.
   Retention Period	Automated backup files are stored for 7 days by default. The backup retention period ranges from 1 to 732 days. If the retention period is less than seven days, the system automatically backs up data every day. The system checks existing automated backup files and deletes the files that exceed the backup retention period you set.
   Time Window	A one-hour period the backup will be scheduled within 24 hours, such as 01:00-02:00 or 12:00-13:00. The backup time is in GMT format. If the DST or standard time is switched, the backup time segment changes with the time zone.
   Backup Cycle	All: Each day of the week is selected. The system automatically backs up data every day. This option is selected by default. Alternative, you can select one or more days in a week. The system automatically backs up data at the specified time.
   Databases and Tables	Select the tables that you want to back up.

   

   A full backup starts within one hour of the time you specify. The amount of time required for the backup depends on the amount of data to be backed up. The more data has to be backed up, the longer it will take.
