Data Backup | Data Backup | The system will trigger a full data backup according to your automatic backup setting within the specified time. The backup method is physical backup, which offers fast backup speed and higher recovery efficiency. The generated full automatic backup data is retained based on the data backup retention time you set. The backup data will not be deleted when the instance is terminated. It will be automatically deleted when it expires. This can meet your need to extend the retention of backup data to prevent serious impact due to accidental deletion of instances. Since full backup uses backup storage space, you can delete it promptly if necessary. The automatic backup data within one week cannot be deleted, while data older than one week can be flexibly deleted according to your needs. Please be cautious when deleting backup data as it cannot be recovered after deletion. |
| Manual Backup | You can manually initiate a full instance backup based on application needs through the console. After the manual backup task is initiated, the system will perform a full instance backup using the physical backup method within 1 minute. The expiration time of manual backups is one week after they are initiated. Since manual backups occupy backup storage space, you can delete manual backups promptly if necessary. |
| Incremental Backup | Incremental backup is WAL log backup, which is automatically enabled by default and cannot be disabled. The incremental backup is stored based on the data backup retention time you set. The system will perform real-time backup based on the WAL log generated by the database. Since incremental backup occupies backup storage space, you can delete it promptly if necessary. Incremental backup data within a week is not allowed to be deleted, while data older than one week can be flexibly deleted according to your needs. After the incremental backup data is deleted, point-in-time recovery cannot be performed, so exercise caution when deleting incremental backup data. |
