Define the three copies
Two folders on the same drive are still one storage failure. Likewise, a phone and laptop that both depend on one synced account may share the same deletion risk.
- Copy one is the working library on the phone or computer.
- Copy two is a local backup on an external drive or NAS you control.
- Copy three is off-site: a second drive stored elsewhere or a trusted remote destination.
Preserve original quality and metadata
Choose original files rather than chat-app copies, thumbnails, or social-media downloads. Keep capture dates, file names, and sidecar files when the photo app uses them. If the destination changes formats automatically, test a small batch first and compare dimensions, file size, date, and location metadata.
Verify instead of assuming
- Compare file counts and total size after the first copy.
- Open recent photos, older photos, videos, portraits, and edited items from the destination.
- Disconnect the source device and open several files again.
- Keep a simple backup log with date, source, destination, and any skipped items.
Make the schedule realistic
A weekly local backup and a monthly off-site rotation works for many personal libraries, but the right interval is the amount of new work you can tolerate losing. Back up immediately after trips, family events, or paid shoots. Encrypt portable media that may leave your control and keep the recovery key somewhere separate.
