Keep a copy outside your working folder

Keep files and attachments together

1. Finish current edits and check that important notes are saved.
2. Copy the full folder to a separate location or use File > Back Up Folder to create a ZIP copy.
3. Open a note from the backup and verify its relative images or links. Keep a dated copy you can identify.

When a backup looks complete but is not

Check hidden or companion attachment folders and files stored outside the notes folder. A copied note can still reference an image that never reached the backup.

Keep a backup outside the working copy

Local version history and a cloud sync service serve different purposes from a tested backup. Keep the backup accessible if this Mac becomes unavailable.
