Similar to this question from 2.5 years ago, so I wanted to ask a similar question for how to backup a larger amount of data at low cost using today's available tools.
I have a home server running windows 7 with a 6 TB raid 5 where I store several TB of media files. Far too much data for Amazon S3 or any online solution. Disks are cheap, but single disks don't come in sizes larger than 3TB. Is there a free or cheap backup tool which would backup my raid volume across multiple physical disks? I don't need the OS, just the data files which are on a disk which is separate from the OS drive. Looking for something cheap because I don't want to spend lots on a home solution.
