With Windows Azure we can use Windows Azure SQL Database service (formerly known as SQL Azure) when we need a Relational Database. Microsoft offers a 99.9% monthly SLA for this service. But Microsoft doesn't provide you with the service to restore your data to a moment back in time when you (accidentally) delete of corrupt data.
To have a backup in time I wrote some code to allow a Worker Role to backup my Windows Azure SQL Database every hour. Most solutions you find online are relying on the REST Endpoints but the address of the endpoint is different depending on which datacenter your database is hosted. I found a different solution where you only need the connection string to your database using the DacServices.
