An Azure backup service that provides built-in management at scale.
Sharing the solution for the benefit of the community.
Problem:
The issue occurred due to creation of multiple backup instances for different disks with the same name through automation. Ideally each name should be unique.
Solution:
To fix the issue, rename all the backup instances so that they will be visible in Azure portal and PowerShell with distinct names. Post that we can call delete operation on them and then delete the vault.
