How to delete a recovery services vault which has a failed backup job and the storage account of the job has already been deleted?

Hi,

You'll need to delete the backup items for the storage account before you can delete the vault: Go to the vault > Backup items > Click the three dots on the far left, 'stop backup' then 'delete backup data.

If there was soft-delete enabled, you'll then need to disable that too, so it removes the items from soft-delete before you can proceed further, see: https://zcusa.951200.xyz/en-us/azure/backup/backup-azure-security-feature-cloud?tabs=azure-portal#enable-and-disable-soft-delete

Once done, you should be able to remove the vault. The Microsoft docs actually has a very good and comprehensive guide on how to do this which you can follow here: https://zcusa.951200.xyz/en-us/azure/backup/backup-azure-delete-vault?tabs=portal#delete-a-recovery-services-vault

Note: this is destructive, it will remove the vault!

Hope this helps, if it does, please mark as accepted so others can benefit from the solution.
