Make 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.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.pxcCluster key should be set to the name of your cluster,

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

   • optionally you can set the metadata.finalizers.delete-s3-backup key (it triggers the actual deletion of backup files from the S3 bucket or azure container when there is a manual or scheduled removal of the corresponding backup object).

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

   apiVersion: pxc.percona.com/v1
   kind: PerconaXtraDBClusterBackup
   metadata:
     finalizers:
       - delete-s3-backup
     name: backup1
   spec:
     pxcCluster: cluster1
     storageName: fs-pvc
   

3. Run the actual backup command using this file:

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