Can I use BackHub to archive my repositories?
Yes, you can use BackHub to archive your GitHub repositories.
Once a backup is complete, you can delete the original repository in GitHub. Since the upstream for creating further backups from the original repository will no longer be available, the backup is archived automatically and listed in a separate section at the bottom of the page.
You can restore the repository back to GitHub from an archived backup anytime.
Note: Not all data can be restored to GitHub directly. The data might come in a different format. Read more here.
