A Backup Plan You Can Actually Restore From
Protect important files with more than one copy, including a copy that routine mistakes or malware cannot erase.

Start with irreplaceable photos, documents, creative projects, and records that would be difficult to recreate. List the devices and folders where those files live, including phones and removable media. A backup is a separate recoverable copy, not merely a folder on the same computer. If the only copy is on a laptop that is lost, damaged, or encrypted by malware, the files are gone.
Keep copies independent
A practical plan might combine an automatic cloud backup with an external drive that is disconnected when not in use. Keep the copies under separate failure modes: synchronization can mirror an accidental deletion, and a connected drive can be exposed to the same malware as the computer. Protect sensitive backups with encryption and a password you can retrieve. For a business or critical archive, consider multiple locations and a written restore procedure.
Test recovery, not just completion
Set a recurring reminder to restore a sample file and check that photos, folder structure, and passwords are usable. Confirm that the backup job actually includes the folders you care about and that the account subscription or storage quota has not expired. Keep the recovery key separately. A successful backup notification is encouraging, but a tested restore is the evidence that your plan works.
