I maintain a Azure SQL database with the Basic plan. 7 days point in time restore is enough for our daily needs. What we are looking to improve is a daily backup outside Azure in the case that we lose access to our Azure subscription for whatever reason.
I have tried using SQLBackupAndFTP with snapshots enabled. Unfortunately it only works on the first backup and consecutive backups then fail. If I crate a new database I get the same behavior. I do not want to disable snapshots since I cannot guarantee that no write operations are done during the backup and I do not want the backup strategy to affect the availability of the web app using it.
