Time Machine Not Backing Up everything

[julianbremann]

Hi, I've been using Time Machine to back up my macbook pro M2 computer since i got it in late 2023, i noticed that it hasn't backed up anything, it does the process, it creates the "backup" directories but when i checked the files there's many directories that are empty. I'm using the same hard drive that i used to back up my previous computer, an external hard drive, when i got the new computer i connected it and selected and started backing up. All the files from the previous computer backups are still on it and they are fine, meaning they are complete, but the new ones don't work. So bascally thankfully I checked, otherwise i might have never noticed. Any idea what's the problem?

Is your external drive dedicated to Time Machine? Is your previous computer another MacBook?
