Well guys i've decided to write a tutorial about this. I'm still testing it, but when it's ready i will post the details.
The idea is based on Lowendspirit but with my own cheap online.net server. Run a few 128MB RAM/2GB HDD OVZ containers on it (5-6) with ports forwarded coz i only got 1 IPV4 address and able to backup these CTs to the free 100GB backup space that online.net provided with the subscription through FTP.
