Backup Resource options

A Backup resource is a Kubernetes object that tells the Operator how to create and manage your database backups. The deploy/backup/backup.yaml file is a template for creating backup resources when you make an on-demand backup. It defines the PerconaServerMongoDBBackup resource.

This document describes all available options that you can use to customize your backups.

apiVersion

Specifies the API version of the Custom Resource. psmdb.percona.com indicates the group, and v1 is the version of the API.

kind

Defines the type of resource being created: PerconaServerMongoDBBackup.

metadata

The metadata part of the deploy/backup/backup.yaml contains metadata about the resource, such as its name and other attributes. It includes the following keys:

• finalizers ensure safe deletion of resources in Kubernetes under certain conditions. This subsection includes the following finalizers:

  • percona.com/delete-backup - deletes the backup resource after the backup data is deleted from storage. Note that it is ignored for incremental backups.

• name - The name of the backup resource used to identify it in your deployment. You also use the backup name for the restore operation.

spec

clusterName

Specifies the name of the MongoDB cluster to back up.

Value type	Example
string	my-cluster-name

storageName

Specifies the name of the storage where to save a backup. It must match the name you specified in the spec.backup.storages subsection of the deploy/cr.yaml file.

compressionLevel

Specifies the compression level. Note that the higher value you specify, the more time and computing resources it will take to compress the data. The default value depends on the compression method used. Read more about compression levels in the Configure backup compression section of PBM documentation.
