How often should I review and migrate photo backups?

Use two review rhythms

After a large import or an important event, check that new photos reached each intended copy. A quick check can be as simple as finding the newest date and opening a few files. Set a fuller annual review for storage capacity, file access, organization notes, and the condition of each backup location. Put both reviews on a calendar with a short checklist so they become part of maintaining the collection.

Look for migration signals

Plan a move when a storage device is no longer convenient to connect, available space is nearly full, a photo program is being replaced, or you cannot easily open and understand the files. Also review after changing computers, phone systems, or the way you organize folders. Migration is a controlled copying and checking task, not an emergency. Starting early gives you time to compare the new location with the old one.

Move in stages

Create the new copy alongside the existing one. Transfer a manageable portion, then open samples from several years and compare folder structure, image files, and photo information. Continue until the new location contains what your checklist requires. Keep a dated note of what was moved and where the current copies are. This record is especially useful when a collection includes both original files and edited versions.

Keep the review focused

You do not need to inspect every image at every review. Check the newest material, older material, a mix of formats, and items with descriptions or edits. Confirm that there is room for the next year of growth and that the away-from-home copy is still distinct from the working library. If any part is unclear, reduce complexity before the next review rather than adding another untracked location.

Before making disruptive changes

• Do not wait for a device or service to become inaccessible before preparing another copy.
• During a migration, preserve the existing usable copy until the new location has been checked with real photos and information.
