Here is what I do to hedge the risk of electrical failure (raid+usb on the same circuit), fire (both copies in same structure), malicious compromise of my machine and theft: - My workstation has linux software raid-1 of 2x 6TiB drives (this provides robustness and uptime in case of single drive failures and ease of recovery). - Another machine in my garage doing incremental daily backup pulls over the network. It is setup as multiple discrete hard drives thus partitioning single drive failures (low cost, the garage is a separate building, the host machine is an arm board that actually turns off HD PSU when not backing up, so hard drives are fairly isolated from power spikes). - I make a monthly incremental backup (three sets) onto an external 6TB usb hard drive encrypted with luks. This drive spends 99% of it's life powered down in a cabinet at my office at work. It is protected against theft, fire, electrical spikes, etc... by my employer. - The is not a *ucking cloud anywhere in this picture. I can get access to my backups within ~1hr in worst case (round trip drive to office to pickup my drive). You Kids need to learn how to take care of your shit - now get off my lawn!!

I use Arq Backup on my workstations, along with Resilio Sync. The NAS holds all our media/documents/music/whatever, and where possible, this gets auto uploaded from workstations to the NAS, mostly through Resilio Sync, but also ChronoSync. A local Raspberry Pi (different building) acts as a node in the Resilio Sync setup, adding more redundancy. The NAS backs up to a local USB drive nightly, as well as a remote (4km distance) Odroid HC2 with a WD Red drive. This device also runs Resilio Sync as a redundant node. All machines run Btrfs where possible, with smart monitoring, daily short smart tests, weekly long smart tests, monthly scrubs, and log monitoring emailed to my inbox every morning. Finally i make yearly archive discs (100GB M-Disc) with the data from the past 12 months. I burn these in 2 copies, one is stored locally, the other is stored remotely. Along with these drives, i also maintain a couple of 4TB USB3 drives, which i freshen (nondestructive badblocks) yearly, and update. Again, one is stored locally, the other remotely with the M-discs. Even with the above setup, there is a theoretical possibility of losing data, but as most data lives on both the NAS and the client machines, as well as a remote target, i would need to lose all 3 at the same time. The only irreplaceable data would be our family photos, and those are also stored on optical and magnetic media (spending 360/365 days powered off), adding at least a couple more layers of redundancy to the equation.
