No, you don’t need an Amazon S3 account to back up your repositories. Rewind Backups for GitHub includes unlimited cloud storage for your backups.
Backup sync to Amazon S3 or Azure is optional and provides you an additional copy in your cloud storage environment.
Keeping an additional copy of your backups is handy if you want to:
- easily access or download all repository backups and metadata at once.
- access your backups anytime, even if GitHub or Rewind were to be unavailable.
- extend the retention period of your backups as per your plan.
- further process your data.
