New Features

Here, we are going to highlight the new features that have been introduced in this release.

Introducing KubeDump Add-on

In this release, we have added Kubedump to our Stash add-ons family. Now, you can backup the YAMLs of your cluster resources using Stash. This add-on lets you backup the YAMLs of an application along with its dependants, all the resources of a particular namespace, and all the resources of the entire cluster.

To know more details about taking backup using KubeDump, please follow the guides from below:

Support cross-namespace Target reference

We are introducing support for cross-namespace Target reference. Now, you can refer to a Target in BackupConfiguration and RestoreSession from different namespaces. So, you can now use a dedicated namespace for keeping Stash resources isolated from your applications. It lets you manage the backup and restore of your applications across all namespaces from the dedicated namespace.

However, these features currently work for database backup only. For workload backup, you must create respective BackupConfiguration or RestoreSession in the application namespace.

To know more details on how you can manage backup and restore from a dedicated namespace, please check the documentation from here .

Add support for topologySpreadConstraints to RuntimeSettings

You can now pass topologySpreadConstraints to BackupConfiguration or RestoreSession through spec.runtimesettings.pod section.

Use restic 0.13.1

We have also updated the underlying restic version to 0.13.1. It fixes some underlying bugs of restic. For more details, please follow the link here .
