Rotating Backups

Hello,

I’m not sure if this is possible but I need a script that backs up to a different drive each week. There is Drive A and Drive B, each week a happens to e.g. Drive A and then at the end of the month it gets changed to Drive B. This is basically drive rotation like on Windows Server but I need it for Windows 10 with two external drives.

I’m sorry if I’ve made this complex but I hope you understand that I need some sort of drive rotation script.

Thank you.
