WHMCS : How to Backup and Sync ?

Dear Members,

A. Introduction :

I am assisting my freind to setup his whmcs and i have theoretical idea of taking backups and sync for whmcs to make the setup redundant and safe from crashes.

B. The Problem :

What if the WHMCS ( the VPS on which its installed ) Fails for any odd reason, How do i address my clients and provide support ?

C. The Proposed Solution : Lets Have 3 VPS Servers :

• primary.com ( having production whmcs )

• backup.com ( having HIDDEN whmcs install , synced with primary.com )

• 911support.com ( Kayako System, ONLY for client support when primary.com fails and we can access ONLY backup.com )

So even if primary.com fails , the staff can access the updated backup.com and provide support vis 911support.com , till primary.com gets online.

D. The Setup :

• Main WHMCS on VPS 1 : primary.com
• Backup WHMCS on VPS 2 : backup.com ( Hidden , Not Publically Available )

E. The Query :

1. Is this setup recommended, or its flawed in someway ?
2. How to sync whmcs databases on VPS1 and VPS2

Im sure this will help many others who wish to make their whmcs setup more redundant and secure.

Thanx.
