A dangerous virus software holds the victim’s computers files for ransom. Yet another reason to have offsite data backup.
This is a simple backup solution for people who run their own web server and MySQL database server on a dedicated or VPS server. Most dedicated hosting provider provides backup service using NAS or FTP servers. These service providers will hook you to their redundant centralized storage array over private VLAN. Since, I manage couple of boxes, here is my own automated solution. If you just want a shell script, go here (you just need to provided appropriate input and it will generate FTP backup script for you on fly, you can also grab my php script generator code).
