We have already introduced immutability for Amazon S3 and Wasabi Hot Cloud storage, which restricts any malicious or unauthorized changes to your data to keep it safe from ransomware or other cyberattacks. With MSP360 Backup 6.0, we have now introduced the immutability (object lock) feature with Backblaze B2 storage.

To start using immutable backups with Backblaze B2, go to the Storage tab, Storage Accounts section and create a new backup destination or edit the existing one. Tick the Allow Immutability box to enable this feature.

Once you are done, proceed to backup plans to enable the Immutability for specific backup plans, along with the GFS retention policy.
