Disaster recovery
Using Schedules and Read-Only Backup Storage Locations
If you periodically back up your cluster’s resources, you are able to return to a previous state in case of some unexpected mishap, such as a service outage. Doing so with Velero looks like the following:
-
After you first run the Velero server on your cluster, set up a daily backup (replacing
<SCHEDULE NAME>in the command as desired):velero schedule create <SCHEDULE NAME> --schedule "0 7 * * *"This creates a Backup object with the name
<SCHEDULE NAME>-<TIMESTAMP>. The default backup retention period, expressed as TTL (time to live), is 30 days (720 hours); you can use the--ttl <DURATION>flag to change this as necessary. See how velero works for more information about backup expiry. -
A disaster happens and you need to recreate your resources.
-
Update your backup storage location to read-only mode (this prevents backup objects from being created or deleted in the backup storage location during the restore process):
kubectl patch backupstoragelocation <STORAGE LOCATION NAME> \ --namespace velero \ --type merge \ --patch '{"spec":{"accessMode":"ReadOnly"}}' -
Create a restore with your most recent Velero Backup:
velero restore create --from-backup <SCHEDULE NAME>-<TIMESTAMP> -
When ready, revert your backup storage location to read-write mode:
kubectl patch backupstoragelocation <STORAGE LOCATION NAME> \ --namespace velero \ --type merge \ --patch '{"spec":{"accessMode":"ReadWrite"}}'
