A personal report published by smyck.net on October 3 describes a plan to store Blu-ray M-Disc backups with trusted friends, adding an off-site copy of essential personal files. The author says three discs currently hold the selected data, but the approach’s long-term reliability and recovery process are not established by the report.
A personal report published by smyck.net on October 3 describes a plan to store copies of essential files on Blu-ray M-Discs in sealed cases held by trusted friends. The author presents the arrangement as a last-resort, off-site backup for data that could be lost if a computer and its nearby backup were destroyed together.
The author says the selected files currently fit on three M-Discs. They include digitized documents organized with Paperless-ngx, selected music and photo collections, and information needed to restart a digital life from a blank computer without access to other devices or backups. The author says the most critical data is zipped and password-protected.
The proposed distribution plan uses two or three cases, each containing several Blu-rays, stored by trusted friends. The author suggests replacing the discs every one to three years and checking that each case’s seal is intact during the handover. The report describes this as a personal plan; it does not say that multiple custodians already hold cases or that any recovery test has taken place.
The author selected a B&W Outdoor Case Type 500, saying it cost €33.74 at the time of purchase and could fit up to five or six Blu-ray jewel cases. The case has latches, a handle and holes for seals. The discs are padded with generic polyethylene foam, chosen because the author wanted material that would not become sticky or degrade over time. A silica gel packet is also included for moisture protection or indication.
A Copy Outside the Home
The plan addresses a weakness in keeping a main computer and its backup in the same home: one disaster could affect both. Placing a copy with another person creates geographic separation, while removable discs do not need to stay connected to a computer or network. The report’s central point is practical: a backup is useful against a particular loss only if it remains accessible after that loss.
The approach also makes the backup a custodial arrangement, not just a storage purchase. Someone needs to hold the case, keep it safe, and return it when the owner refreshes the discs. Choosing what to preserve and whether a custodian should have the password involves trade-offs between privacy and future access. The author raises digital legacy as one possible consideration, noting that relatives may struggle to manage accounts after a person dies if they lack credentials.
This is an individual account rather than a controlled evaluation of archival media. It documents one person’s choices and reasoning, but offers no measured comparison of M-Disc longevity, no failure-rate data and no evidence that the specific kit has survived years of storage. Readers should treat the longevity rationale as the author’s motivation, not a verified result of this project.

From Disc Purchase to Custody
The author says the idea followed an earlier blog post about buying a Blu-ray drive and M-Discs for archival backups. While burning the first discs, they considered what data they would most regret losing and how a copy stored at home could still be vulnerable to a catastrophic event. The proposed solution borrows from a familiar practice: leaving a spare house key with a trusted friend for emergencies.
The physical kit is designed around that arrangement. The case is intended to protect jewel cases from ordinary knocks, dust and moisture, while foam limits movement. A numbered plastic seal, which the author says must be broken to open, provides a visible sign of possible access. The author plans to photograph the seal and compare its barcode and number when refreshing the backup. They acknowledge that a determined person might reproduce a seal; the described check is meant to suit their own security needs and threat assumptions.
The report also highlights that not every file needs to be included. The author selected documents, music, photos from trips and events, and materials for rebuilding access to a digital life. That scope is personal and deliberately selective; the author says other people would define essential data differently.

Reliability and Recovery Questions
The report does not establish how long the discs will remain readable under the planned storage conditions. It gives no independent test results, environmental measurements or history of successful restores from these specific discs. The author’s planned refresh cycle is a precaution they chose; the report does not show that it is necessary or sufficient.
Practical recovery details also remain open. The report does not specify a complete process for checking that every file was written correctly, periodically reading the discs, or restoring the archive if the original drive fails. It does not say whether a compatible Blu-ray drive would be kept with the case or how a custodian could obtain one. The password is another unresolved choice: keeping it separate may protect confidentiality, but could make the files inaccessible if the owner cannot provide it.
The article is a personal account, not independent reporting on media performance. The author says the security arrangement is not fully disclosed. The number of cases actually distributed, whether recipients have agreed to hold them, and whether the handover plan has been put into practice are not clear from the provided report.

Testing the Backup Plan
The author’s stated next step is to store the cases with trusted friends and refresh the discs on a roughly one-to-three-year schedule. At each handover, the author plans to inspect the seal, compare its identifying details with a photograph, and provide a new case only if the old one appears intact. The report does not give a date for the first handover or say whether that process has begun.
For the plan to work as a recovery measure, the owner would also need to confirm that the copied files can be read and that the password and needed software or instructions are available when required. The report does not describe those checks as completed. Any later account of a restore test, a disc refresh or an actual retrieval from a custodian would show how the arrangement works beyond its initial design.

Key Questions
What is the author proposing?
The author proposes keeping copies of essential files on Blu-ray M-Discs in sealed cases held by trusted friends, creating an off-site backup for a severe loss at home.
What files are included?
The author says the current set fits on three discs and includes digitized documents, selected music and photos, and materials for restarting a digital life from a blank computer. The selection is personal, not a standard checklist.
How often does the author plan to replace the discs?
The proposed schedule is every one to three years, with the author checking the case seal during each handover. The report does not present this interval as a tested industry rule.
Has the report proven that the discs will last for decades?
No. The report describes the author’s backup design and motivation, but provides no long-term readability tests or independent evidence establishing how long these specific discs will remain usable.
