Should ALL locally created GIT branches be pushed to the central-repository on a daily basis? What is best-pracice workflow concerning this?
We created a GIT repository
I agree with you, using a central repo for backup of daily work is a bad idea. It should hold commits meant to be shared, tested or released.
Backup of daily work should either happen to another repo, more permissive, with optionally an automated git push --force --all backup-repo
task on each dev machine, or have them a more classic backup tool.
