Making on-demand backup

1. To make an on-demand backup, you should first check your Custom Resource for the necessary options and make changes, if needed, using the deploy/cr.yaml configuration file:

   • the backup.enabled key should be set to true,

   • backup.storages subsection should contain at least one configured storage.

   You can apply changes in the deploy/cr.yaml file with the usual kubectl apply -f deploy/cr.yaml command.

2. Now use a special backup configuration YAML file with the following keys:

   • metadata.name key should be set to the backup name (this name will be needed later to restore the bakup),

   • spec.clusterName key should be set to the name of your cluster (prior to the Operator version 1.12.0 this key was named spec.psmdbCluster),

   • spec.storageName key should be set to the name of your already configured storage.

   • optionally you can set the spec.type key to physical if you would like to make physical backups instead of logical ones (please see the physical backups limitations). Otherwise set this key to logical, or just omit it.

   You can find the example of such file in deploy/backup/backup.yaml:

   apiVersion: psmdb.percona.com/v1
   kind: PerconaServerMongoDBBackup
   metadata:
     finalizers:
     - delete-backup
     name: backup1
   spec:
     clusterName: my-cluster-name
     storageName: s3-us-west
     type: logical
   

3. Run the actual backup command using this file:

   $ kubectl apply -f deploy/backup/backup.yaml
