How often are backups for Github updated?

Backups occur on a daily basis. Snapshots are kept for 30 days for Professional and Individual plans, and for 365 days for Enterprise Plans.

Backups are updated on a daily basis. The backup routine is usually active during nighttime hours in Pacific Time. 

The timestamp of the latest complete backup of your GitHub repository displays when you open the panel of a backup.

The specific time when your backup is created or updated may vary. This is because each account has an API rate limit and we queue backups randomly across all accounts to balance this API rate limit.
