Database Rollback
Document Database provides comprehensive data backup and rollback functionality to help you ensure data security and support rapid data recovery in case of data loss or misoperations.
The data rollback feature allows you to restore the database to a specified point in time based on existing backups.
Backup Mechanism
The system automatically backs up the database every day as the data source for the rollback feature. The entire process is handled by the system; you do not need to configure or trigger it manually.
- Backup time: A backup task runs automatically every day between 02:00 and 06:00 (Beijing time)
- Backup retention: Backup files are retained for 7 days by default. Only backups within the retention period can be used for rollback; backups past their retention period are automatically cleared and can no longer be used
- Recoverable range: The time points available for rollback are determined by existing backups — the earliest you can recover to is the oldest backup within the retention period, and the latest is the time after the most recent backup completes. The exact selectable time points are subject to the list shown in the console's rollback interface
