These two commands will minimise the diskspace used for the repo. Please note that Github, BitBucket run this all the time to minimise the diskspace.
Suggestion: Run as often as you can (i.e. once a week for small working-in-progress repo, one in every few days if many people work together).
It's no harm to run it often, cron or system task could be an option too.

# Clean unused commits
`git reflog expire --all --expire=now`

# Compact the disk by remove unneccesary files from the local git repository
`git gc --aggressive --prune=now`
