Thank you for your feedback. We would like to get more feedback about this item before we prioritize. Is the ask here to replicate a storage account on-demand ? Or have a mechanism to always keep two or more storage accounts in sync ?
Meanwhile, to unblock some of our users we have published a sample that copies blobs from an account to another account: https://docs.microsoft.com/en-us/azure/storage/scripts/storage-common-transfer-between-storage-accounts?toc=%2fpowershell%2fmodule%2ftoc.jsonAndrew commented
We would live this for our Release process. Making changes to table storage is a one way process with no way to revert if you make a mistake.
Also being able to backup ones table and blob storage is a must for us. Using AZ copy works but takes ages and is clunky at best. It also relies on someone doing it right. Having a button in the portal would be great.
