Incremental backups with git bundle, for all branches

Question

What is the easiest way to do incremental backups of a git repository with git bundle?

If I just wanted to backup a single branch, I could do something

Answer 1

Try using --since with --all.

Create the first backup:

git bundle create mybundle-all --all

Do an incremental backup:

git bundle create mybundle-inc --since=10.days --all

The incremental should contain all commits on all branches that have happened in the past 10 days. Make sure the --since parameter goes back far enough or you might miss a commit. Git will also refuse to create the bundle if no commits have happened in that time-frame, so plan for that.
