The Tao of Backup

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Three prevalent themes in the discussion

  1. Cost and practicality of backup media
    Commenters weighed HDDs, Blu‑ray/M‑Disc, LTO tapes, and cloud storage (S3/Glacier) in terms of price per TiB, convenience, and long‑term reliability.
  2. “Even if you account for consumer drive+spare cost, a 8TB HDD is still the best JBOD option… For under several dozen 25GB projects, the BD‑R disc drive is currently the cheapest media backup option (about 35% cheaper than HDD above 12TiB).” – Joel_Mckay
  3. “I looked in to the bluray thing and concluded it just doesn't make sense at any level… just getting a hard drive makes way more sense even if the $/gb is technically a little worse.” – Gigachad
  4. “Blu‑ray, or any non‑rewritable optical media, guarantees that it hasn't been tampered with.” – computator

  5. “AWS is an option up to 30TiB… The recent 'rclone --gui' solution does bestow rsync/sshfs like features for Windows users now.” – Joel_Mckay

  6. Nostalgia for the early web and lament over today’s content consumption
    Several users expressed missing the open, blog‑centric Web and criticized how social media has shortened attention spans.

  7. “I miss the World Wide Web, man…” – happyrock
  8. “Social media cannibalized most of the interesting blogs, and 92% of people no longer have the patience to scroll more than 1/2 a page of text.” – Joel_Mckay
  9. “Hard same. Perusing small blogs over feeds any day of the week.” – kombookcha

  10. “Nice Epilogue” – jmclnx (referring to a nostalgic‑style backup guide)

  11. Ensuring backup integrity and protection against tampering/ransomware
    The conversation highlighted techniques (write‑once media, encryption, checksums, offline copies) to trust that backups remain unchanged and recoverable.

  12. “If I were attacked by malware, I like the confidence that the Blu‑ray backup is absolutely guaranteed to be the same as on the date it was written.” – computator
  13. “In terms of external tampering, I think that need is better‑served by encrypting everything… However if the focus is 'what if the backup process is compromised', then yes, having some date which is beyond its writing‑reach may be useful.” – Terr_
  14. “I've been down 'LTO at home?' rabbit‑hole… I realized that S3 Glacier is tape‑as‑a‑service.” – nxobject
  15. “The novice said: 'I will save my working files, but not my system and application files...' … If that's your situation, it might be worth backing up applications. However, there are better solutions that make this irrelevant. For instance, using NixOS, you can literally back up a single text file describing your system setup…” – dbdr (Tao of Backup excerpt)

SecuriBack: Cross-Platform App‑Aware Backup Assistant

Summary

  • Provides automated, encrypted backups for Windows and Android with built‑in support for Signal, Photos, and generic folders, plus optional cheap cloud sync (B2/S3 Glacier) and tamper‑evident hash logs.
  • Core value proposition: Simple, secure, cross‑platform backup that protects personal app data without requiring macOS/iPhone.

Details

| Target Audience | Privacy‑conscious individuals using Windows and Android who want reliable backups of personal apps and files. | | Core Feature | App‑aware backup engine (Signal, Photos, generic folders) with encryption, local repository, optional cloud sync, and integrity verification via hash sampling. | | Tech Stack | Electron/Tauri (desktop) + React Native/Flutter (mobile), Rust backend (libsodium, restic/rclone), Svelte WebUI for management. | | Difficulty | Medium | | Monetization | Revenue-ready: Freemium (free local backup, $5/mo for cloud sync). |

Notes

  • Addresses deknos’ request: “please extend for * windows * android * specific applications like * signal * photos”.
  • Provides a practical utility that could spark discussion on open‑source backup tools and cross‑platform security practices.

VerifyLite: Low‑Cost Backup Integrity Sampler

Summary

  • Verifies backup integrity by downloading only a small random sample of chunks from cloud storage, using a pre‑computed Merkle tree or hash list, cutting egress costs dramatically.
  • Core value proposition: Cheap, fast verification for inexpensive cloud backups (S3 Glacier, B2) without full restores.

Details

| Target Audience | Individuals and small teams using low‑cost cloud storage for backups who need affordable verification. | | Core Feature | Client‑side hash index; on verification request, downloads a configurable fraction of chunks (e.g., 0.1%) and compares hashes, reporting mismatches. | | Tech Stack | Go or Rust CLI, AWS SDK, B2 SDK, optional Electron GUI. | | Difficulty | Medium | | Monetization | Hobby (or Revenue-ready: One‑time $10 license). |

Notes

  • Directly tackles sdcfgy’s complaint: “S3 is too expensive to do a restore from. And you have to restore to verify.” and nxobject’s Glacier retrieval cost concern.
  • Could enable new workflows for backup verification and inspire discussion on efficient integrity‑checking techniques.

BlogWave: Single‑Page Small Blog Reader

Summary

  • Aggregates RSS/Atom feeds from personal blogs into a clean, single‑page infinite‑scroll reader with offline caching, dark mode, and optional self‑hosting.
  • Core value proposition: Restores the pleasure of perusing small blogs over feeds, free from social‑media clutter and pagination pain.

Details

| Target Audience | Users who miss the early web, enjoy reading small blogs, and seek a low‑distraction reading experience. | | Core Feature | Feed aggregation, offline reading via Service Workers/IndexedDB, single‑page UI, exportable reading list. | | Tech Stack | SvelteKit (or Next.js), IndexedDB, Service Workers, Docker for self‑host option. | | Difficulty | Low | | Monetization | Hobby (or Revenue-ready: Donation‑supported). |

Notes

  • Resonates with Joel_Mckay: “Social media cannibalized most of the interesting blogs, and 92% of people no longer have the patience to scroll more than 1/2 a page of text.” and kombookcha: “Hard same. Perusing small blogs over feeds any day of the week.”
  • Addresses xnx’s pain about multi‑page layouts and could revive interest in indie‑web blogging and feed‑based discovery.
