7 steps for archiving your files for posterity

Lincoln Spector | May 28, 2015
We really don't know how long our photos and other digital content will last. But you can increase the odds that your great-grandchildren will enjoy the digital record of your life.

Doug Schofield asked about "long-term storage for my most important data: My family tree, irreplaceable photos, interviews, and audio recordings."

I have family photos that go back more than 100 years. But I can't be sure that, a hundred years from now, my descendants will have my photos.

No one knows for how long your files will be accessible. Both file formats and physical media can go out of fashion. And the media itself may not be stable over the long haul. I can't guarantee anything, but these steps will increase the odds that your descendants can know their ancestors.

1. Pick file formats with staying power

Think about the formats in which you should save your archival files. Select open formats that are widely used and readable by many current programs. For instance, programs that can display JPGs will probably be around longer than ones that support camera-specific RAW files.

Other good formats include PDF, DOCX, MP3, MP4, and MOV. If possible, save and store the same files in multiple formats.

2. Don't encrypt

You need to encrypt your credit card information and your passwords, not your family photos. It will be hard enough for your descendants to find and open the files without looking for a long-lost password.

3. Store archival files on your main drive

Whether it's a hard drive, an SSD, or something not yet invented, keep your files on the main storage unit inside your computer. When you upgrade to a new drive or a new PC, you'll want transfer all your data--including your archival files. That provides insurance against the degradation or loss of the older drive.

4. Set files to read-only

Designating files as read-only adds a layer of protection against accidentally deleting or overwriting precious data.

To make your archival files read-only in Windows, right-click the folder containing them and select Properties. Check Read-only. Clicking OK or Apply will bring up another dialog. Select Apply changes to this folder, subfolders, and files.

5. Make your archives part of your regular backup

Back up regularly, and make sure that the folders containing archival material are part of the daily routine. If you don't have a regular backup routine, now would be a good time to start.

6. Burn files to optical discs, but choose the right discs

CDs, DVDs, and Blu-ray discs have some serious archival advantages. They're write-once, so you can't accidentally erase or overwrite a file. And you can make multiple copies cheaply and easily, sending them out to family and increasing the odds that one disc will survive.
