Time Machine could not create a local snapshot to back up from

Good morning !


I tried to do a back up of my mac for the first time (it's a 2017 Macbook air that works with Catalina - Version 10.15.4)

I used an external Disk, and when I tried it says "Time Machine could not create a local snapshot to back up from".

I'm not very familiar with computers, can someone help me ? Thanks a lot.


MacBook Air 13", macOS 10.15
