A long time ago, I used CrashPlan for backups. They had support for Linux, and I had a Linux server at the time that ran ownCloud and some other services that needed backups. I pointed CrashPlan at the appropriate directories and let it roll. Fast forward several years, I needed to restore something (non-critical) and it was a giant pain in the ass. I was able to get it done, but it wasn't immediately clear that I would be able to. Something about CrashPlan not retaining deleted files and some of my paths changing or something. Anyway, I was so frustrated by the whole experience that I dumped CrashPlan. I run Syncthing to provide file sync services. A Raspberry Pi acts as the "central server" on my home network. Once a night, an EC2 instance launches, syncs the data up, and then performs an offline backup to S3. I get a report e-mailed to me every night so I can keep tabs on stuff. I did have to spend time building it out, but it costs something like $5 per month and it's been bulletproof. Lots of love for Syncthing over here. It's been a champ.
