You put alot of time into that!!!
It's been a 4 long years endeavor. And I back it up like you wouldn't believe. The backup is encrypted (twice) with a VERY long password generated with Keepass. That backup is stored at my cloud provider, a non-public Amazon AWS S3 bucket, my local FTP server in the house, on all of my computers, on DVD/RW and Blu-ray RE. The backup right now is about 230 MBs so not really a large database like this site would have. But If by an absolute miracle social media drops in favor of the traditional forum-based website and I grow, I'll just split the encrypted backup file in sections with Gsplit and use multiple 50 GB Blu-ray disks if necessary. LOL
Really sucks that I'm stuck with 50 GB per Blu-ray disk. I was hunting down and researching my actual ass off trying to find a Blu-ray burner drive from a reputable, good company that burned 100 GB disks and M-disc as well. Alas, I was stuck with this Pioneer Blu-ray drive that can burn M-disc and Blu-ray up to 50 GB only. I may just buy a 100 GB Blu-ray burner without M-disc capability just for the 100 GB capability. If I need M-disc I'll use the other drive. That's why computer cases have multiple 5.25 drive bays after all.
Did I mention all of my computers and USB drives are encrypted and stored in a couple fireproof safes?
Plus, my whole computer clones are encrypted and those external HDDs are in the safes as well. I don't care about the safe having a lock, I just want my data fireproof. The lock on these $35 fireproof safes meant for electronics can be easily defeated with a flat head screwdriver. Theft is not so much of an issue either. I have cameras, a Ring door bell, a .380 upstairs in the living room, one in the downstairs living room and one in my bedroom. LMFAO!
