How often should I commit?

The frequency at which you commit changes to your repository is going to depend on your workflow and goals with using Copia for source control. The prevailing wisdom for how often you should commit when using Git is "commit early, commit often".

Since Copia doesn't limit your storage, frequent commits aren't going to impact you beyond increasing the size of your repository. If one of your main goals of using Copia is to have more recovery points to revert back to when things go bad to reduce lost work, then frequent commits are a must. Alternatively, if you are doing some prototyping or exploratory coding, then maybe you'd only commit once or twice a day.
