DRS automatic backups
By default, CDP Private Cloud Data Services 1.5.4 and higher versions enable Data Recovery Service (DRS) automatic backups for the Control Plane, CDE, and CDW in the compute cluster of ECS. The automatic backups are stored in the Longhorn in-cluster storage. You can also configure the external storage in ECS, and then initiate the automatic back ups to it.
The following storage options are available to store the DRS automatic backups in ECS:
- In-cluster storage
- By default, DRS automatic backups use Longhorn in-cluster storage. If necessary, you can configure the storage configuration settings in Longhorn by navigating to the page.
- External storage
- ECS uses Longhorn as the underlying storage provisioner. In Longhorn, you can store snapshots externally using an S3 compatible storage such as Ozone or NFS v4. After you configure the external storage, edit the automatic-backup cron job to initiate the automatic backups.
Configuring external storage in ECS for DRS automatic backups
Before you initiate Data Recovery Service (DRS) automatic backups to the external storage in Longhorn, you must complete the prerequisites.
Initiating DRS automatic backups
After you configure the external storage in ECS, you can initiate the Data Recovery Service (DRS) automatic backups using the “updateAutoBackupPolicy” CDP CLI command. Alternatively, you can edit the “automatic-backup” (a Kubernetes cron job) to initiate the DRS automatic backups.
