By far the safest, easiest, cheapest way to back up photographs (and other work) is a collection of external drives. Plain, ordinary, cheap-as-chips external hard drives. 5TB drives are in the sweet spot at present.
When you take some photographs, simply copy the whole lot onto an external drive. Then unplug the drive. Store it somewhere the computer isn't.
Next time you take photographs, copy to a DIFFERENT external drive. Copy both folders (today's and yesterday's). And so on. From time to time, drop a worst-case-scenario copy in somewhere where you aren't - you brother's house, say, or the office. Anywhere that isn't in the same building subject to the same flood, fire and nuclear weapon risks. (Well, flood and fire anyway.) Use the same principles for other data.
Remember that any backup device connected to your computer isn't really a backup at all. One single power surge, one single virus infection, one single user brainfade can delete the whole lot, instantly. The only worthwhile backup is offline. And one spare copy isn't good enough. You need at least three. (More is better - and why not given it is so cheap and easy?)
Don't frig about with fancy software, compression, NAS, do-it-for-you stull that never works properly - in backup, brute force rUlEz. It is faster, simpler, cheaper, easier, and above all safer. Send that other thing back, it's pointless.
