You can change cluster-level, backup-to-object storage settings that you set when activating NetApp Backup and Recovery for each ONTAP system by using the Advanced Settings page. You can also modify some settings that are applied as "default" backup settings. This includes changing the transfer rate of backups to object storage, whether historical snapshots are exported as backup files, and enabling or disabling ransomware scans for a system.

Note These settings are available for backup-to-object storage only. None of these settings affect your Snapshot or replication settings.
Note To switch to and from NetApp Backup and Recovery workloads, refer to Switch to different NetApp Backup and Recovery workloads.

You can change the following options in the Advanced Settings page:

  • Changing the storage keys that give your ONTAP system permission to access object storage

  • Changing the ONTAP IPspace that is connected to object storage

  • Changing the network bandwidth allocated to upload backups to object storage using the Max Transfer Rate option

  • Changing whether historical snapshots are exported as backup files and included in your initial baseline backup files for future volumes

  • Changing whether "yearly" snapshots are removed from the source system

  • Enabling or disabling ransomware scans for a system, including scheduled scans

View cluster-level backup settings

You can view the cluster-level system settings and provider settings for each system.

Steps

  1. From the Console menu, select Protection > Backup and recovery.

  2. From the Volumes tab, select Backup Settings.

  3. From the Backup Settings page, select the More icon for the system and select Configure advanced settings > System settings to view system settings and Configure advanced settings > Provider settings to view provider settings.

    The resulting page displays the current settings for that system. When viewing provider settings, the provider settings shown are relevant for the bucket that you select at the top of the page.

Note that some options are unavailable based on the version of ONTAP on the source cluster and the cloud provider destination where the backups reside.

Change the network bandwidth available to upload backups to object storage

When you activate NetApp Backup and Recovery for a system, by default, ONTAP can use an unlimited amount of bandwidth to transfer the backup data from volumes in the system to object storage. If you notice that backup traffic is affecting normal user workloads, you can throttle the amount of network bandwidth that is used during the transfer using the Max Transfer Rate option in the Advanced Settings page.

Steps

  1. From the Volumes tab, select Backup Settings.

  2. From the Backup Settings page, click More icon for the system and select Configure advanced settings > System settings.

  3. In the Advanced Settings page, expand the Max Transfer Rate section.

  4. Choose a value between 1 and 1,000 Mbps as the maximum transfer rate.

  5. Select the Limited radio button and enter the maximum bandwidth that can be used, or select Unlimited to indicate that there is no limit.

  6. Select Apply.

This setting does not affect the bandwidth allocated to any other replication relationships that may be configured for volumes in the system.

Change whether historical snapshots are exported as backup files

If there are any local snapshots for volumes that match the backup schedule label you're using in this system (for example, daily, weekly, etc.), you can export those historic snapshots to object storage as backup files. This enables you to initialize your backups in the cloud by moving older snapshots into the baseline backup copy.

Note that this option only applies to new backup files for new read/write volumes, and it is not supported with data protection (DP) volumes.

Steps

  1. From the Volumes tab, select Backup Settings.

  2. From the Backup Settings page, click More icon for the system and select Configure advanced settings > System settings.

  3. In the Advanced Settings page, expand the Export existing snapshot copies section.

  4. Select whether you want existing snapshots to be exported.

  5. Select Apply.

Change whether "yearly" snapshots are removed from the source system

When you select the "yearly" backup label for a backup policy for any of your volumes, the snapshot that is created is very large. By default, these yearly snapshots are deleted automatically from the source system after being transferred to object storage. You can change this default behavior from the Yearly Snapshot Deletion section.

Steps

  1. From the Volumes tab, select Backup Settings.

  2. From the Backup Settings page, click More icon for the system and select Configure advanced settings > System settings.

  3. In the Advanced Settings page, expand the Yearly Snapshot Deletion section.

  4. Select Disabled to retain the yearly snapshots on the source system.

  5. Select Apply.

Enable or disable ransomware scans

Ransomware protection scans are enabled by default. The default setting for the scan frequency is for 7 days. The scan occurs only on the latest snapshot.

For details about DataLock and Ransomware Resilience options, refer to DataLock and Ransomware Resilience options.

You can change that schedule to days or weeks or disable it, saving costs.

Tip Enabling ransomware scans will incur extra charges depending on the cloud provider.

If the scheduled ransomware scans are disabled, you can still perform on-demand scans and the scan during a restore operation will still occur.

Refer to Manage policies for details about managing policies that implement ransomware detection.

Enable or disable ransomware scans for a system

You can enable or disable ransomware scans for a cluster.

Steps

  1. From the Volumes tab, select Backup Settings.

  2. From the Backup Settings page, click More icon for the system and select Configure advanced settings > System settings.

  3. In the resulting page, expand the Ransomware scan section.

  4. Enable or disable Ransomware scan.

  5. Select Scheduled ransomware scan.

  6. Optionally, change the every week default scan to days or weeks.

  7. Set the how often in days or weeks that the scan should run.

  8. Select Apply.

Enable or disable ransomware scans for a provider

You can enable or disable ransomware scans at the provider level by using the provider settings page. The settings on the page are relevant to the bucket that you select at the top of the page.

Steps

  1. From the Volumes tab, select Backup Settings.

  2. From the Backup Settings page, click More icon for the system and select Configure advanced settings > Provider settings.

  3. At the top of the resulting page, select the bucket for which you need to change settings.

  4. Expand the Ransomware scan section.

  5. Enable or disable Ransomware scan.

  6. Select Scheduled ransomware scan.

  7. Optionally, change the every week default scan to days or weeks.

  8. Set the how often in days or weeks that the scan should run.

  9. Select Apply.
