A couple of my friends have their own business, and wanted to backup their data to a different location.
They wanted to do offsite storage backup, but don't want to pay a hefty price of cloud service.
I offered to setup a VPN connection and COPY their data to my place (NAS device), which is about 20
minutes from my house. Therefore they would have copies at both places (their business and my home).
However, I don't know what I should charge them to keep a backup of their data.
Thoughts?
