You have just finished scanning a box of old family photographs and saved the files to the external drive that sits on the kitchen counter. The next step—making sure those images survive a power surge, a hard‑drive failure, or a flood—often gets overlooked. A single drive is only a copy, not a safeguard, and relying solely on an online service leaves the collection vulnerable to service outages or account loss. The following checklist walks you through a practical, layered approach to keep the digital record of your family history safe for decades.
One copy is not a backup
A single hard drive holds the data, but it is also a single point of failure. Mechanical wear, accidental deletion, or a virus can erase the files in moments. Cloud storage, while convenient, depends on a remote provider’s infrastructure, subscription status, and your login credentials. If the provider experiences downtime, changes its terms, or you lose access to the account, the collection disappears. Treat both as parts of a larger strategy, not as the whole solution.
To protect against these risks, duplicate the files on at least two different media and keep one copy separate from your primary location. This redundancy reduces the chance that any single event wipes out the entire archive.
The 3‑2‑1 rule in plain terms
The rule translates to three total copies of every file, stored on two different types of media, with at least one copy kept off‑site. In practice, you might keep the original files on your computer, a second copy on an external SSD, and a third copy in a cloud account. The two media types could be a magnetic hard drive and a solid‑state drive, or a hard drive and a USB flash drive. Off‑site means any location not subject to the same physical hazards—such as a different house, a safe deposit box, or a trusted relative’s home.
Checklist:
1. Verify original files on your primary computer.
2. Copy to a second physical device (different technology).
3. Upload a third copy to a cloud service.
4. Store the off‑site copy in a location that is not vulnerable to the same disaster.
Choosing durable file formats
File formats that are open, well‑documented, and widely supported have the best chance of remaining readable for thirty years. For photographs, use lossless formats such as TIFF or high‑quality JPEG with minimal compression. Documents are safest as PDF/A, an archival version of PDF that embeds fonts and metadata. Audio recordings should be saved as WAV, and video as MP4 with H.264 codec, both of which are industry standards. Avoid proprietary formats that may become obsolete without a clear migration path.
When converting legacy media, keep the original file alongside the new version until you have confirmed the conversion succeeded and the new file meets your quality standards.
Free and low‑cost cloud options for archives
Several reputable providers offer free tiers that can serve as the off‑site copy in a 3‑2‑1 plan. Google Drive, Microsoft OneDrive, and Dropbox each grant several gigabytes of storage without charge; upgrades to 100 GB or more are inexpensive on a yearly basis. For larger collections, consider Amazon S3 Glacier Deep Archive or Backblaze B2, which charge only a few cents per gigabyte per month and are designed for long‑term retention. Choose a service that supports versioning, so accidental overwrites can be recovered.
Before uploading, organize files into clearly named folders that mirror your local structure. Enable two‑factor authentication to protect the account from unauthorized access.
Automating backups and labeling devices
Automation removes the reliance on memory. On Windows, use File History or a third‑party tool that mirrors designated folders to an external drive on a schedule. macOS offers Time Machine, which can back up to multiple drives. For cloud sync, set up the provider’s desktop client to monitor the same folders and upload changes in real time. Schedule the tasks to run nightly, and verify that the backup logs show successful completion.
Label each physical backup device with a consistent scheme, such as “FamilyArchive_2024_ExternalSSD” and “FamilyArchive_2024_HDD”. When you add a new drive, update the label to reflect the date and media type, and record the label in a master inventory file stored both locally and in the cloud.
Verifying backups and handling originals
The most commonly skipped test is a full restoration of a random sample of files. Once a month, pick five files from different folders, copy them from each backup location to a separate folder, and open them to confirm they are intact and readable. If any file fails, investigate the cause and recreate the missing copy before the next scheduled backup.
Physical originals—film reels, audio tapes, printed letters—should be stored in a climate‑controlled environment after digitisation. Use acid‑free sleeves for photographs, and place reels in airtight containers with silica packets to mitigate humidity. Keep a short inventory that links each physical item to its digital counterpart, stored both the inventory and the digital files together.
Worth remembering: Apply the 3‑2‑1 rule using open formats, automate the copy process, and regularly test restores; this layered approach keeps family history files safe without relying on any single device or service.
Common questions
What should this resource include?
The resource should include a concise explanation of why multiple copies are needed, a step‑by‑step 3‑2‑1 checklist, recommendations for long‑term file formats, low‑cost cloud options, instructions for automating backups, labeling conventions, and a simple test for verifying backup integrity.
Can I use it digitally and on paper?
Yes, the checklist can be saved as a PDF for digital reference and printed for a physical copy. Keeping a paper version in a safe place provides an offline reference if the computer is unavailable.
How should I customize it for my family?
Adjust the storage capacities to match the size of your collection, select cloud services that fit your budget, and modify the labeling scheme to include family‑specific identifiers such as surnames or project names. Tailor the test sample to include the most valuable media types you have.
