I am in need of a simple low-maintenance off-site backup solution for one or more Windows servers. I have had great success using some consumer-grade backup software that allows me to backup files from one PC to another through the Internet. I've installed this on my own personal computers, as well as several other computers in our office. It has several nice features that make it reliable, easy to maintain, and cost-effective.
I don't know why, but it just feels dirty to install consumer-grade software on my servers. Are there any legitimate reasons to avoid consumer-grade software, or is my feeling justified?
These servers don't handle sensitive data other than source code. These are not public Internet servers either; they are only accessed by a team of software developers on a VPN.
Side note: I'm aware of other easy off-site backup solutions meant specifically for servers. For one reason or another, I can't use most of them. That's besides the point though; this question is not as much about backup software as best practices.
