I thought it was good practice to shut down the computer every night. Does it still do things in the background when shut down?

If the computer is shutdown there is will probably no Electrical Power to both the computer and TM Backups drive - right ?

 A Time Machine Backup  is very useful.

You are welcome 👍 and thank you too 🇨🇦
