Error: Unable to delete backup in the Capacity Tier because it is immutable

I was recently involved with a Veeam deployment that was running into problems during testing, their only performance tier had run out of space. Though this wasn’t unexpected as the disk provisioned was undersized and just temporary until testing was finished, it was preventing new backups from finishing successfully.

The full performance tier belonged to a Scale-Out Backup Repository that was also configured with a capacity tier (copy + move mode) backed by an immutable AWS S3 bucket. Worth mentioning those backup files in the capacity tier were still within the immutability retention period.

According to the user guide “If you use the scale-out backup repository, keep in mind that the Delete from disk operation will remove the backups not only from the performance tier but also from the capacity and archive tier. If you want to remove backups from the performance tier only, you should move those backups to the capacity tier instead. For details, see Moving to Capacity Tier.”

Attempting to perform a “Delete from disk” operation was failing with the error “Error: Unable to delete backup in the Capacity Tier because it is immutable”.

Understanding Cloud Computing

Great analogy for cloud computing.

Imagine if tap water didn’t exist. Every household would need to dig a well. Doing so would be a pain. Wells are expensive to build and expensive to maintain. You wouldn’t be able to get a large quantity of water quickly if you needed it—at least not without upgrading your pump. And if you no longer needed the well, there would be no store to return it to, and no way to recoup your capital investment. If you vacated the house, or the proper plumbing was installed in your house, you would have invested in a well you don’t need.

Tap water fixes all of that. Someone else spends the money and builds the right plumbing and infrastructure. They manage it and ensure that the water is clean and always available. You pay only for what you use. You can always get more if you want it.

That, in a nutshell, is what cloud computing is all about. It is data center resources delivered like tap water. It is always on, and you pay only for what you use.
