But by far the greatest security is backups. Periodically Backup the entire FTP directory and your database. Take both and archive them in a SFX archive from 7-Zip using AES 256 with a long password using a password manager like Keepass.
I backup my websites and my computers and encrypt all of that. They are stored on my local FTP server, external hard drives, DVD/RW and Blu-ray RE and stored in a couple fireproof safes.
I'm a backup freak let me tell you.
No harm in that though. At least I won't get caught with my pants down, owned and tea bagged. I
, do the tea bagging on the games I play.
