It may be a good product idea to build a box PC with redundant hard drives and ZFS set up in paranoia mode to scrub every so often in order to refresh the data it guards, and configure it with safe defaults such that it works as a vault(not having provisions to run Docker etc.). Want to access photos, hook it up with an ethernet cable and access it like this... Once done, leave it in the closet with power supply. I wonder how many would buy such a box..
Don’t overlook the probability of a fire or burglary or flood causing the loss of everything in the closet. RAID and file system redundancy won’t help in that case. You need multi-site backup anyway, and then file system failures are also covered.
True. Perhaps it should be able to back itself up to something like AWS Glacier or Backblaze B2 such that the data can be retrieved by the owners if they have the encryption key somewhere.
