TL;DR

  • ·Format obsolescence and cloud service closure are real threats to long-term data survival — widely adopted open formats like JPEG and UTF-8 plain text outlast proprietary formats, and any single cloud service is a single point of failure
  • ·The OAIS model's core distinction applies at the personal level: uploading is not preserving — preservation requires periodic verification, format migration, and distributed copies across independent locations
  • ·Paper with acid-free standards can outlast any digital medium, but it requires no software to read; the practical strategy is to combine media, verify every few years, and migrate formats before obsolescence forces it

When your child turns 50, will the records you're keeping right now be readable?

Fifty years is a time scale that's hard to imagine when you're deep in the infant months. But if the intended recipient of these records is your child herself — the person who will grow up, have children of her own, outlive you, and eventually reach old age — then that full arc of time is the delivery window. Whether photos, videos, and text survive to reach her is a technical question, but it connects directly to why you're recording in the first place.

There is a body of research in information science and digital preservation that has been accumulating these answers for decades. What it says, applied to a box of baby photos and a cloud-backed parenting app, is worth knowing.
