As of right now, one of the cheapest offsite backup solutions by far is BackBlaze B2, with Amazon S3 trailing behind. For a while now, I’ve been using this solution with a piece of software called restic to store encrypted backups of some of my important documents offsite. By doing so, should my Western Digital 8TB external hard drive (which I currently use for all of my backups) fail, or get stolen (it’s strongly encrypted, so my data is safe), I have a solution to get the files I need the most back. While I store anything and everything on my external, I am limiting the files in the offsite backup to things that are important. It’s not economical to push things like your music/movie collection, Linux ISOs and virtual machine hard drive images to the BackBlaze cloud. Ubuntu’s repositories contain the restic binaries, but other distributions may require you to install a new repository or build from source. I could write up a guide on how to set this up, but Fedora Magazine wrote an excellent article on how to setup this exact solution. I’d be doing anyone reading this a disservice trying to write up an article that better explains the setup steps. If you’re not a huge fan of restic, duplicity also supports BackBlaze B2, and is fairly easy to setup from what I hear.
