Our project is very simple.
1) Configure a third party (backup) Centos server to support rsync/samba so that it will be able to receive cPanel incremental backups using samba mount.
2) Configure a cPanel (main) hosting server to rsync incremental backups daily to a third party server directly using samba mount. [no backup data will be stored on the main server, it all goes directly to backup server]
3) Write step-by-step instruction for dummies how to setup this themselves.
Both servers are Centos based and running cPanel.
