The Redis management console supports manual backup of DCS instance data. You can manually back up data in DCS instances in time when you need to. By default, manually backed up data is permanently retained. You can delete it manually if you need to.
Before You Begin
A DCS instance in the Running state.
Procedure
1. Log in to the Redis management console.
2. Select the region of the instance in the upper left corner of the management console.
3. On the instance list page, click the target instance name to go to the instance details page.
4. In the instance node list, click the Redis cluster name to go to the Redis cluster management page.
5. Select the Backup Management tab on the left side to go to the backup management operation page.
6. Click the Manual Backup button and the confirmation window for backup operation will pop up. Click OK again to start a manual backup task.
7. Then, the backup management page displays the backup information (including: backup point, backup status, type, restoration status). If the backup status is success, the backup is completed.
Description
l Redis instances use RDB snapshot storage to implement persistence. It saves memory data at a certain moment to files on the hard disk. The read-write performance of the data will not be affected during the backup period.
l During the backup period, do not change the password, expand the capacity, etc. for the instance.
l Backup period: It is recommended to schedule the backup for off-peak hours.
