I have just used an external disk to backup my Macbook Air via Time Machine before installing Mojave. Can anyone tell me if the original internal drive backup still exists?

I have just used an external USB to backup my MacBook Air via Time Machine before installing Mojave. Can anyone tell me if the original Time Machine internal drive backup still exists, or do I have to keep the external drive connected all the time for backups? Thanks!
