Setting up WHMCS backups
As with all your hosting data it's important to ensure you have regular backups or your databases and configuration files.
Krystal offers Backups Pro as an option on Reseller Hosting - which increases your backups stored from 4x weekly and 1 x monthly to 30 x daily Snaphots.
WHMCS also offers some backup options - either to email a backup of the WHMCS database to an address you choose, or to send the database backup to an off-site SFTP/FTP location. Note this does not include important files like the WHMCS configuration.php - so you should make sure you have an appropriate backup strategies in place.
