# Enable or Disable Auto-scaling

Enable or disable auto-scaled access nodes for an existing client at the protocol level or for individual subclients.

Important

- Auto-scaling supports streaming backups. Pre- and post-backup scripts are not supported.

- When you enable auto-scaling for a client, the first job that runs is a Reconcile Backup job. The Reconcile Backup job validates configuration and aligns backup metadata before standard backup operations continue.

## Enable auto-scaling for a backup protocol

1. From the Command Center navigation pane, go to Protect > Files.

2. Go to the Files tab, and then click the file server.

3. Go to the Protocols tile, and then click CIFS or NFS.

4. Go to the protocol Configuration tab.

5. In the Access nodes tile, click Edit.

6. Click Use Auto Scale.

7. From the Credential list, select the credential that contains the AWS STS AssumeRole ARN.

8. Click Submit.

9. Click Yes to overwrite the backup access node configuation for all subclients associated with the protocol and apply auto-scaling.

Note

If a scale config already exists for the selected credential, the system reuses it; otherwise the system creates a scale config automatically for the credential. When a scale configuration is active, the UI disables selection of permanent access nodes for that protocol.

## Enable auto-scaling for a single subclient

Note

If the protocol uses a permanent access node, enabling auto-scaling at the subclient-level overwrites the configuration for the selected subclient. Use Overwrite access nodes on subclients at the protocol level to change every subclient consistently.

1. From the Command Center navigation pane, go to Protect > Files.

2. Go to the Files tab, and then click the file server.

3. Go to the Protocols tile, and then click CIFS or NFS.

4. On the Subclients tab, click a subclient.

5. Go to the subclient Configuration tab.

6. On the Access nodes tile, click Edit.

7. Click Use Auto Scale.

8. From the Credential list, select the credential that contains the AWS STS AssumeRole ARN.

9. Click Submit.

## Disable auto-scaling to use permanent access nodes

Note

Disabling auto-scaling does not delete the scale config. The scale config remains available if you re-enable auto-scaling for the credential later.

1. From the Command Center navigation pane, go to Protect > Files.

2. Go to the Files tab, and then click the file server.

3. Go to the Protocols tile, and then click CIFS or NFS.

4. Go to the protocol Configuration tab.

   To disable auto-scaling for a subclient, click the subclient and go to the subclient Configuration tab.

5. On the Access nodes tile, click Edit.

6. From the Acces nodes list, deselct the scale configuration.

7. Select the permanent access nodes that you want to use, and then click Save.
