Can we create a credential using SAS Key for an Azure File Share with extension .file.core.windows.net and Backup an Azure SQL Database onto it; Right Now i receive the Error "Error while decoding the storage key."
Microsoft has some fantastic documentation on exactly how to get your backups done in Azure VMs. Pretty much everything you need. Don't forget though, untested backups are unknown. The only complete test is a restore. Strong recommendation to test restores regularly.
