How to set the retentions for the Windows server backup?

This is using MS Windows Server Backup on Windows server 2012 r2. The window server backup is used to backup C:\, and E:\Exchange databases, and this scheduled backup is seems working fine. The backup destination is a network mapped drive, with total disk space of 1.2 TB, which is enough to store, let's say more 2 weeks' data.

I was running the Windows server backup wizard, in which I have to go to the task scheduler to modify from every single schedule backup on each day to only Monday to Friday. However, I don't see any settings for retentions. If I want to have a data retentions for let's say, 20 days, how can i set it?

Thanks in advance.

As far as I know you cannot set retention with Windows Server Backup in 2k8\2k8R2\2K12\2K12R2

In TechNet link it says:
If you are backing up to a hard disk or volume you can specify a deletion policy to determine whether backups should be deleted only when necessary to make space for additional backups or if they should be deleted after a certain number of backups have passed.

But I never found this feature with W2K12 and W2K12R2, it might available in Windows online backup feature with Azure

You need to use DiskShadow utility to manually delete old backup copies (Shadows Copies)
