Protect apps with snapshots and backups

Protect all apps by taking snapshots and backups using an automated protection policy or on an ad-hoc basis. You can use the Astra Control Center UI or the Astra Control API to protect apps.
-
Helm deployed apps: If you use Helm to deploy apps, Astra Control Center requires Helm version 3. Managing and cloning apps deployed with Helm 3 (or upgraded from Helm 2 to Helm 3) are fully supported. Apps deployed with Helm 2 are not supported.
-
(Openshift clusters only) Add policies: When you create a project for hosting an app on an OpenShift cluster, the project (or Kubernetes namespace) is assigned a SecurityContext UID. To enable Astra Control Center to protect your app and move the app to another cluster or project in OpenShift, you need to add policies that enable the app to run as any UID. As an example, the following OpenShift CLI commands grant the appropriate policies to a WordPress app.
oc new-project wordpress
oc adm policy add-scc-to-group anyuid system:serviceaccounts:wordpress
oc adm policy add-scc-to-user privileged -z default -n wordpress
You can do the following tasks related to protecting your app data:
Configure a protection policy
A protection policy protects an app by creating snapshots, backups, or both at a defined schedule. You can choose to create snapshots and backups hourly, daily, weekly, and monthly, and you can specify the number of copies to retain.
If you need backups or snapshots to run more frequently than once per hour, you can use the Astra Control REST API to create snapshots and backups.
|
Offset backup and replication schedules to avoid schedule overlaps. For example, perform backups at the top of the hour every hour and schedule replication to start with a 5-minute offset and a 10-minute interval. |
|
If your app uses a storage class backed by the ontap-nas-economy driver, protection policies cannot be used. Migrate to a storage class supported by Astra Control if you want to schedule backups and snapshots.

-
Select Applications and then select the name of an app.
-
Select Data Protection.
-
Select Configure Protection Policy.
-
Define a protection schedule by choosing the number of snapshots and backups to keep hourly, daily, weekly, and monthly.
You can define the hourly, daily, weekly, and monthly schedules concurrently. A schedule won't turn active until you set a retention level.
When you set a retention level for backups, you can choose the bucket where you'd like to store the backups.
The following example sets four protection schedules: hourly, daily, weekly, and monthly for snapshots and backups.
-
Select Review.
-
Select Set Protection Policy.
Astra Control implements the data protection policy by creating and retaining snapshots and backups using the schedule and retention policy that you defined.
Create a snapshot
You can create an on-demand snapshot at any time.
|
|
If your app uses a storage class backed by the ontap-nas-economy driver, snapshots can't be created. Use an alternate storage class for snapshots.
|
-
Select Applications.
-
From the Options menu in the Actions column for the desired app, select Snapshot.
-
Customize the name of the snapshot and then select Next.
-
Review the snapshot summary and select Snapshot.
The snapshot process begins. A snapshot is successful when the status is Healthy in the State column on the Data protection > Snapshots page.
Create a backup
You can also back up an app at any time.
|
S3 buckets in Astra Control Center do not report available capacity. Before backing up or cloning apps managed by Astra Control Center, check bucket information in the ONTAP or StorageGRID management system. |
|
|
If your app uses a storage class backed by the ontap-nas-economy driver, be sure that you have defined a backendType parameter in your Kubernetes storage object with a value of ontap-nas-economy before performing any protection operations. Backups for apps backed by the ontap-nas-economy are disruptive and the app will be unavailable until the backup operation has completed.
|
-
Select Applications.
-
From the Options menu in the Actions column for the desired app, select Back up.
-
Customize the name of the backup.
-
Choose whether to back up the app from an existing snapshot. If you select this option, you can choose from a list of existing snapshots.
-
Choose a destination bucket for the backup from the list of storage buckets.
-
Select Next.
-
Review the backup summary and select Back up.
Astra Control creates a backup of the app.
|
|
If your network has an outage or is abnormally slow, a backup operation might time out. This causes the backup to fail. |
|
|
If you need to cancel a running backup, use the instructions in Cancel backups. To delete the backup, wait until it has completed and then use the instructions in Delete backups. |
|
|
After a data protection operation (clone, backup, restore) and subsequent persistent volume resize, there is up to a twenty-minute delay before the new volume size is shown in the UI. The data protection operation is successful within minutes, and you can use the management software for the storage backend to confirm the change in volume size. |
View snapshots and backups
You can view the snapshots and backups of an app from the Data Protection tab.
