Palette Virtual Clusters are a capability that cluster groups support and that you can enable when creating a cluster group. By default, the virtual cluster settings in a cluster group disable disk backups. You can back up all the volumes within a virtual cluster using the following steps.
A project or tenant backup location. Refer to the cluster backup and restore document to learn how to configure a backup location.
Cluster group modification permissions.
A cluster group. Review the create a cluster group for additional guidance.
You can also enable virtual cluster disk backup during the cluster group creation process.
- Log in to Palette.
- Navigate to the left Main Menu and select Cluster Groups.
- Select a cluster group to enable virtual cluster disk backup.
- Click Settings and expand the Settings Menu.
To enable disk backup you need to change the following configurations in the Advanced Config section.
- Set
syncer.extraArgs.rewrite-host-paths
totrue
syncer:extraArgs:- --rewrite-host-paths=true- Set
hostpathMapper.enabled
totrue
hostpathMapper:enabled: true- Set
podSecurityStandard
toprivileged
isolation:podSecurityStandard: privileged- Set
Setting the podSecurityStandard
to privileged
can introduce privilege escalations. We recommend you discuss this with your security system administrator.
- Save your changes.
All virtual clusters deployed in this cluster group will now include disk storage during backup operations.
You can validate the disk backups are occurring by deploying a virtual cluster and taking a backup.
- Log in to Palette.
- Deploy a virtual cluster in your cluster group that has the disk backup settings enabled. Refer to the Deploy a Virtual Cluster to a Cluster Group guide to learn how to deploy Palette Virtual clusters.
- Create a backup of your virtual cluster and include all disks. Use the Create a Cluster Backup guide for additional guidance.
- Access the backup location's blob storage and review the backup files.
