Neil Gelder shows how to back up directly to Azure blob storage:
The URL is the one from the container we made a note of and the credential is the one we created in the last step.
Now if we return to the container screen in the Azure Console and refresh the screen you’ll see your backup file like below
My personal preference here would be to back up locally and then have a job migrate backups to Azure or S3. That storage is 1-3 cents per GB per month (and even cheaper if you’re willing to store the data in Glacier), so for more small to mid-sized organizations running databases in the tens of gigs, it’s a great way of getting around only being able to store a week or two worth of backups on-site.
