About Object Lock (Immutability)

Object Lock (Immutability) is a feature that locks backup datasets for a period specified by GFS retention policy. Within this period, backup data is kept unmodified.

Object Lock (Immutability) is supported by the following storage providers:

• AWS
• Wasabi
• Backblaze B2

The Object Lock (Immutability) feature is linked with the GFS retention policy. If the Immutability is applied along with GFS settings, full backups that are subject to the GFS retention policy become immutable for the GFS keeping period.

For example, if in a backup plan you enable weekly and monthly GFS keeping periods, and then enable Immutability, it means that all weekly and monthly backups selected by the GFS keeping period assignment mechanism will be locked on backup storage and cannot be deleted nor modified.

Retention Modes for Immutable Data

Generally, two object lock retention modes are supported for immutable storage:

• Governance mode (default)

  In Governance mode, protected objects in backup storage are locked (users cannot overwrite or delete an object version or alter its lock settings using Management Console or Backup Agent). These objects can only be deleted using cloud storage provider tools. By design, when you create a destination bucket using the Management Console, the Governance mode is used for all destination buckets with Immutability enabled.

• Compliance mode

  In Compliance mode, protected objects in backup storage are locked completely (users cannot overwrite or delete an object version or alter its lock settings using Management Console or Backup Agent). These objects cannot be deleted until their retention period defined in the GFS retention policy settings ends. Management Console or Backup Agent provide no option to switch object lock retention mode for existing destination buckets. If you need to use the Compliance mode for the case, you can check this option with MSP360 support.

Allow 'Manage Object Lock (Immutability)' Permission for Your Administrators

If you intend to delegate the Immutability management to your administrators, grant the appropriate permission for them. To do this, proceed as follows:

1. Open the Management Console.
2. In the Organization menu, select Administrators.
3. Click Edit or Add Administrator to create a new one.
4. Switch to the Permissions tab.
5. Find the Manage Object Lock (Immutability) option, then select the appropriate checkbox.
6. Click Save.

Allow Object Lock (Immutability) for Storage Account

If you need to comply with the regulations, maintenance or legal requirements, or anything else that requires an immutable backup dataset, enable this feature for an appropriate storage account. If you do not have any storage destinations with the allowed Object Lock (Immutability), you can create a new destination bucket in Management Console.

AWS S3

To allow Object Lock (Immutability) for AWS S3, proceed as follows:

1. Open the Management Console.
2. In the Storage Accounts, select the required account to allow the Object Lock (Immutability) or create a new storage account.

3. Click the gear icon, then select View Backup Destinations.
4. Click Add Destination Bucket to create a new backup destination for immutable backups.
5. In the Destination Bucket property box, fill in the required data (create or select an existing bucket), then click Enable Object Lock (Immutability).

6. Confirm the action: read the confirmation message, select the I Confirm Enabling Object Lock (Immutability) checkbox, then click Confirm.
7. Once you are done, proceed to backup plans to enable the Immutability for specific backups along with the GFS retention policy. The allowed Immutability enables this feature on the specified bucket only and does not apply this feature to any backups. You should apply immutability to desired backups as described below.

Wasabi

To allow the Object Lock (Immutability) for Wasabi, proceed as follows:

1. Open the Management Console.
2. In the Storage Accounts, select the required account to allow the Immutability or create a new storage account.

3. Click the gear icon, then select View Backup Destinations.
4. Click Add Destination Bucket to create a new backup destination for immutable backups.
5. In the Destination Bucket property box, fill in the required data (create or select an existing bucket), then click Enable Object Lock (Immutability).

6. Confirm the action: read the confirmation message, select the I Confirm Enabling Object Lock (Immutability) checkbox, then click Confirm.
7. Once you are done, proceed to backup plans to enable the Object Lock (Immutability) for specific backups along with the GFS retention policy. Note that allowed Object Lock (Immutability) enables this feature on the created bucket only and does not apply to any existing buckets or backups. Proceed to enable the Immutability in backup plans as described below.

Backblaze B2

To allow the Object Lock (Immutability) for Backblaze B2 destinations, proceed as follows:

1. Open the Management Console.
2. In the Storage Accounts, select the required Backblaze account to allow the Immutability or create a new Backblaze storage account.
3. Click the gear icon, then select View Backup Destinations. If you just created a new Backblaze storage account, just follow the storage account creation wizard.
4. Click Add Destination Bucket to create a new backup destination for immutable backups.
5. In the Add Destination Bucket box, select the Create new bucket option, specify the new bucket name, then select the Enable Object Lock (Immutability) checkbox. If you want to use the existing bucket, click ..., then select the required bucket from the list.

6. Confirm the action: read the confirmation message, select the I confirm enabling Object Lock (Immutability) checkbox, then click Confirm.
7. Once you are done, proceed to backup plans to enable the Immutability for specific backups along with the GFS retention policy. Note that the Object Lock (Immutability) feature is applied to the created bucket only. Proceed to enable the Object Lock (Immutability) in backup plans as described below.

If you need to suspend or terminate immutable backup keeping, proceed as follows:

1. Open the Management Console.
2. In the Storage > Storage Accounts, select the required account.
3. Click the gear icon, then select View Backup Destinations.
4. Click the ... button to edit an existing destination.
5. In the Edit Destination Bucket property box, clear the Enable Object Lock (Immutability) checkbox.

Enable Object Lock (Immutability) in Backup Plans

To enable Object Lock (Immutability) in backup plans via Remote Management, proceed as follows:

1. Open the Management Console.
2. In the Computers menu, select Remote Management.
3. Find the required computer, then click the gear icon.
4. Select Show Plans.

7. Follow the backup wizard to the Retention Policy step.
8. Enable the GFS retention policy, then specify the GFS keeping periods according to your requirements. If you already have the GFS policy configured, skip this step.

8. Select the Enable Object Lock (Immutability) checkbox.
9. Confirm the feature enabling, then follow the backup wizard steps to save the backup plan configuration.
