how to backup linux ubuntu server?

Question

Hi. We have a VOIP Server at the office and i cant figure out how i can back up it. The way i am thinking is using a program like Acronis® True Image Echo™ Server for Linux but it cost to dam much, need a free software or any other ways of backing up entire hdd or partion. I need to be able to backup the image onto a extrenal hdd and i wont mind getting my hands a little bit dirty with coding if needed or whatever. Thank You For Helping In Advance!
