Today we are going to create a Kasten backup to an immutable Backblaze Bucket in the cloud.
Login to your Backblaze account and create the immutable Bucket:

I will name it kastenimmutable:


Make sure to jot done the endpoint:

Next we need to add an application key:



Now lets head back to Kasten and create the location Profile:

Further down check mark the “Enable Immutable Backups” box and proceed to validate the bucket:

We forgot to put a default retention on the bucket. Kasten requires a 21 day default retention set on the bucket:

Back in the Backblaze console click the Object Lock Highlighted text and add the retention:


Now our validation succeeds:


Now we will create a new backup and export the snapshot to our Backblaze immutable bucket:

In the policy make sure to enable Backups via Snapshot Exports and point to our Backblaze location:

Finally run the policy:

That’s it, our policy is now safely backed up offsite in an immutable bucket!
