Currently, WHMCS can only backup using FTP/SFTP, CPanel Backup and Email. Technology is advancing in light speed and users would like to have their data on-the-go nowadays. Convenient, secure and easy access.
Implementing backup to File Hosting Service/Cloud Storage, will allow an administrator or system engineers to check on their back up on the fly rather than be restricted to a particular storage of their own. It would be nice to have backups to some major File Hosting Service provides as such below,
2) Google Drive
Just to name a few. It will nice if WHMCS team could integrate the major ones first and then expand the list with other providers.
