Enable dynamic ANF pools for self-managed clusters

Contributors dmp-netapp

When backing up a managed app in a private on-premises cluster that has an ANF storage backend, you must enable the dynamic ANF pools feature. This is done by providing a subscription ID to use when expanding and contracting the capacity pools.

Note Dynamic ANF pools is feature of the Astra managed apps that use an Azure NetApp Files (ANF) storage backend. When backing up these apps, Astra automatically expands and contracts the capacity pools the persistent volumes belong to by a factor of 1.5. This ensures there is enough space for the backup without incurring an additional permanent charge. See Azure application backups for more information.

1. Add the Azure subscription identifier

Perform the following REST API call.

Note You need to update the JSON input example as appropriate for your environment, including the subscription ID and the base64 value for the service principal.
HTTP method Path

POST

/accounts/{account_id}/core/v1/credentials

2. Add a bucket if needed

You should add a bucket to the managed application if needed.

3. Take a backup of the managed app

Perform the workflow Create a backup for an app. The capacity pool where the original persistent volume is present will expand and shrink automatically.

4. Review the event log

Activity events are logged during the backup. Perform the workflow List the notifications to view the messages.
