We have a Master database and a Failover replica database set up. If Nickelled's Master server went offline the application will automatically connect to the failover database and keep serving traffic.
We have automated daily backups which is provided by our cloud infrastructure provider.
We also have automatic backups that run every 6 hours which we manage and are placed in Object storage.
The final fail safe we have in place is that once every 24 hours the backup for that day is placed on a different cloud providers network so if one of the providers went down permanently or for an extended period we can recover the service in on a new providers infrastructure.
