PolarDB supports data backup and redo log backup. When you back up data, you create a backup set of all data on a cluster at a specific point in time. A backup set is also known as a snapshot. When you back up redo logs, you record the incremental data that is generated after a backup set is created. You can configure policies for data backup and redo log backup. For example, you can specify the frequency of automatic data backups, the retention period of data backup files, the storage location, and the retention period of log backup files.
Navigate to the details page of the cluster for which you want to configure backup settings. In the left-side navigation pane, choose Backup Settings tab.. Click the
Click Edit. In the dialog box that appears, configure parameters in the Back up Data, Log Backup, and General sections.
