External drive space for Time Machine

With a MacBook Air 512GB internal drive, I'm wondering if 1TB is enough space. I do realize old backups are erased when the drive is full.


Thoughts?


Thanks!

The normal recommendation is two to three times the size of your internal. It should be fine. It just affects how far back in time things are backed up.
