Configuring an Incremental Backup Policy

Precautions

• To enable or disable incremental backup, contact customer service.
• After incremental backup is enabled, the incremental backup type is differential backup by default. If you want to select PITR backup, contact customer service.

Enabling Incremental Backup

1. Log in to the management console.
2. In the service list, choose Databases > GeminiDB Cassandra API.
3. On the Instances page, click the instance you want to enable incremental backup for and click its name.
4. Choose Backups & Restorations in the navigation pane one the left, and click Modify Backup Policy. In the displayed dialog box, enable incremental backup.

5. Select an incremental backup type. Differential backup is selected by default.
   • Differential backup: Data can be restored to a specific point in time.
   • PITR backup: Data can be restored to any point in time.

6. (Optional) Select Create a backup immediately after the incremental backup policy is modified. If you select this option, the system starts a full backup and the incremental backup policy takes effect immediately. If you do not select this option, the policy takes at the next full backup.
