I'm hosting with ThePlanet and while I love their services, their backup services are a bit pricey. To backup my whole server (incrementally) would cost $50/mo on top of my server fee (around $120). I want to host all of my sites there on the same server for ease of use and to make it more affordable. The problem I run into is backups. HostGator offers unlimited disk space and backups. I'm considering setting up WHM so it does FTP backups to a machine located at my house on a secondary hard drive.
What do you guys think of this? Are there better backup services out there I'm unaware of, or is this my most affordable option?
Incremental backup options would be preferred
