Split up a long project - how?

Set Left and right markers to 1st song.
Save as ‘song name’
Mix, overdub, enjoy.

Set markers to next song.
Save As ‘Next song name’
Continue mixing, overdubbing and enjoying,

Etc, Etc, All the files will be save to the same folder, making the backing up a doodle as everything including all the project files will be in the same spot.

I work this way for every album I record and it seems to fit my personal workflow, interesting to reads others flow too though. Nice thread.
