OneDrive Backups of Backups ?

[ReprobusR]

Does Microsoft make OneDrive backups of your back up, and if so; is it daily or weekly ? And can you access those backups ?

Your device makes backups to OneDrive, determined by the settings for backup. You can see they are there and the date created but all you can do is delete them.
OneDrive, gear icon, options
Backups are created by device name. A new backup on the same device just overwrites the old. You can have more than one backup for a device by changing its name.
For Win 10 phone the name is in settings, system about, same location on a PC.
The backup is there until it is deleted or overwritten.
