Configure automated backup
Automated backups run once daily at a specified time. You can configure them during cluster creation or through the cluster management menu. This setting is available only when the number of nodes is at least 2. When changing the backup retention period or start time while the automated backup option is enabled, the changes apply to newly created backups going forward.
While a backup is being created, you cannot add/delete/promote nodes or delete the cluster.
During cluster creation
- Go to KakaoCloud Console > Data Store > MemStore.
- Click Create Cluster.
- Fill in the automated backup settings and click Create.

Create manual backup
You can manually create a backup in MemStore under the following conditions:
- The cluster must be in
Runningstate - A replica must exist

Restore
To use the restore function, a backup must be created beforehand. You can create a new cluster from the selected backup file.
- Restoration is only possible in the same cluster mode as the backup.
- Restoration supports the same or higher Redis engine version than the backup.
Restore may fail if the cache size of the source backup exceeds 60% of the memory of the target cluster flavor.
Restore from cluster details

- Select the cluster using the backup.
- In the Backup menu, click [More] for the target backup > Restore.
