For long-term data preservation, I'd ditch the "depends on XYZ cloud service next year" approach. The most bulletproof combo I've tested so far is **encrypted local storage on multiple high-quality hard drives** plus **offline quarterly checksum verification**. Get 2-3 4TB+ HDDs (WD Red, Seagate IronWolf – not the "desktop gaming" ones), encrypt each with Veracrypt in AES-256 mode, and store copies at two different physical locations. Every 3 months, boot a live Linux USB, mount the drives, run `sha256sum -c *.sha256` against your checksum file, and log the verification. If any drive starts showing reallocated sectors or checksum mismatches, retire it immediately and clone to a new one. For that extra 20-year guarantee layer, supplement with M-Disc 50GB DVDs (they’re proven to hit 1,000 years at 80°C/176°F) – just don’t rely on them alone. Stuff 10-15 of them in an archival-grade sleeve, label with a fine-point Sharpie, and check one randomly every 3 years. Wrote a tiny Python script that automates checksum generation and DVD writing logs – saves me from forgetting which disc was burned when.
