<span style="font-family: helvetica; font-size: 12pt;">I will suggest something and let people rip it apart:<br><br></span>Get two RPis that have at least USB 2.0 Attach two large capacity disks to each one in a RAID-1 configuration (also known as "mirroring") to keep it simple. If one disk fails the other will still keep working (but you should replace it as soon as possible).
<br>
<br>Put all of your data on both systems.
<br>
<br>Take one of your systems to a friends or relatives house who you trust that has relatively good WiFi. Make sure the friend is relatively close, but is not in the same flood plain or fire area you are.
<br>
<br>Do an rsync every night to keep them in sync.
<br>
<br>Help your friend/relative do the same thing, keeping a copy of their data in your house. If your disks are big enough you could share systems and disks.
<br>
<br>Use encryption as you wish.
<br>
<br>Disk failure? Replace the disk and the data will be replicated.
<br>Fire, theft, earthquake? Take the replaced system over to your friends/relatives and copy the data at high speed, then take the copied system back to your house and start using it again.
<br>
<br>You would need three disks to fail at relatively the same time to lose your data. Or an asteroid crashing that wipes out all life on the planet. Unlikely.
<br>
<br>Realize that nothing is forever.

For the second time in 3 months I have had a computer failure. Oddly, it was a PS on the motherboard both times. (Two different MB's.) Fortunately the disks were ok. I'm living on borrowed time. Next time, I may not be that lucky.

Need a file server system with some sort of RAID redundancy. I want to backup 2 main computers, plus photos. Maybe this RPI4 too, since that's what I'm running on, due to the second failure. If this SSD goes, I'm gonna be a sad puppy. This is for home use, so we are not talking Exabytes. I'm thinking about 2-4TB of RAID. Unless of course, RAID is obsolete these days. Honestly, I find some of the levels of RAID confusing. I want something that will survive a disk failure (or two) out of the array. Have any ideas, or can you point me to some place that discusses this somewhat intelligently?

Are there reasonable systems that one can put together oneself these days? Can I repurpose an older PC for this purpose? Or an RPI4? What are the gotchas of going this way?

I want to be able to set up a daily rsync or equivalent so we will lose as little as possible. At the moment, I'm not thinking about surviving fire or disaster. Maybe I should, but I suspect the costs balloon considerably. I do not want to backup to the cloud because, plain and simple, I don't trust it to be fully secure.

Thanks for any and all suggestions.
