I'm not seeing the expected behavior of Azure Backup regarding retention. Since Azure Backup is charged by the amount of data stored, we intend to keep the cost as low as possible by only storing the most recent backup. That is, we expect to only pay for the storage costs of one day's worth of recover points, which in our case will be one because we do only one backup per day. We are still performing onsite backup, and there we keep many days worth of backup recovery points.
On the Microsoft Azure Backup application's main screen, under "Destination usage" it shows "Retention: 1 days". However, I see under "Available Recovery Points" it shows "Total backups: 15", "Latest copy: 12/29/2014 4:30 AM", "Oldest copy: 12/19/2014 12:35 PM". When I visit the Recovery Services "PROTECTED ITEMS" onhttps://manage.windowsazure.com/, I see the number of "RECOVERY POINT", "NEWEST RECOVERY POINT", and "OLDEST RECOVERY POINT" shown match the same values displayed on the Microsoft Azure Backup application's main screen.
Why is Azure Backup retaining more recovery points than expected? Why is it retaining recovery points for more days than requested?
