Well. There are several steps to go thru. If you want the backup at a certain time of day, you’ll need a real-time-clock. The arduino won’t know human time. Something like this would help. https://www.adafruit.com/product/3013

or you’d need something that can connect to the internet for real time like am esp32.

obzrve why do you want to "control the power"?? Are you running Linux Backups are easy. plug in your stat drive and kick off a cron job. Even if you still want to "control the power with a arduino. you will have to wait for the OS to find the drive and spin up. skip the arduino and go straight to the cron job.
