  Table 3 backup_policy field data structure description

  Name	Mandatory	Type	Description
  keep_days	Yes	Integer	Backup retention days The value ranges from 1 to 732.
  start_time	Yes	String	Backup time window. The creation of an automated backup will be triggered during the backup time window. The value cannot be empty. It must be a valid value in the "hh:mm-HH:MM" format. The current time is in the UTC format. The value of HH must be 1 greater than the value of hh. The values of mm and MM must be the same and must be 00. Example value: 21:00-22:00
  period	Yes	String	Full backup period. An automated full backup will be created on the specified days of the week. The value is a number separated by commas (,), indicating the days of the week. For example, 1,2,3,4 indicates that the backup period is Monday, Tuesday, Wednesday, and Thursday.
  differential_period	Yes	String	Differential backup interval. Interval for automatic differential backup. Its value can be 15, 30, 60, 180, 360, 720, or 1440. The unit is minute. Example value: 30
  rate_limit	No	Integer	Upload speed at which data is uploaded to OBS. 0 MB/s indicates that the speed is not limited. The upload speed is related to the bandwidth. Value range: 0-1024 Minimum value: 0
  prefetch_block	No	Integer	Number of prefetch pages from the modified pages in the disk table file during a differential backup. When modified pages are adjacent (for example, with a bulk data load), you can set this parameter to a large value. When modified pages are scattered (for example, random update), you can set this parameter to a small value. The default value is 64. Value: 1 to 8192 Minimum value: 1. Maximum value: 8192
  file_split_size	No	Integer	Size by which full and differential backup files are split, in GB. The value is from 0 to 1024, but it must be a multiple of 4. The default value is 4. 0 indicates the size is not limited. Value range: 0-1024 Minimum value: 0 Maximum value: 1024
  filesplit_size	No	Integer	Size by which full and differential backup files are split. Deprecated field. Leave it blank.
  enable_standby_backup	No	Boolean	Whether to enable backup on a standby node. (It is not suitable for single-node instances and instances earlier than 3.100.0.)
