server Need help backing up a server to Google Drive.

[NvGBoink]

So here is my issue at work we have roaming profiles so all our user data is stored on our server here in the office. Now we do run regular back ups to a back up server on the other side of the school but my boss now wants us to also backup the whole server (Or just the user files) to A cloud service like google drive. Now we have Unlimited Google drive storage so preferably we want to use Drive.

My question is does anybody use any software that does this well ?
I'm looking at Cloud Berry

but I don't want to just jump onto the first program I find if there is a better (cheaper) alterantive out there ?
