This week, I encountered an annoying issue when deleting some resources, specifically Azure Backup Vaults (and recovery service vaults). I was deleting a resource group that contained several resources, including a backup vault. The delete started fine, and all the other resources got deleted, but the vault and the resource group did nothing for a long time before the deletion timed out with no further information.
The issue is that when you attempt to delete a resource group, it attempts to delete all the resources inside it, including the backup vault.
Recently I came across a question on StackOverflow that was asking about how they could backup Azure Blob storage. They finished this question asking I can’t be the only one who needs to do this”. This struck a chord with me, as I recall feeling exactly the same when I had a need to do this. It feels like something that is so obvious, that should be built into the platform.
Disaster recovery is, or should be, a must for for many production applications. Having the ability to recover your application in a separate geographic location should a major incident occur is vital to the continued availability of your service. Microsoft have offered a DR service called Azure Site Recovery (ASR) for some time now, but this has been focused on taking on-premises applications and providing a DR solution for these in Azure.
