The best strategy for backing up your photos is to apply the 3-2-1 rule: keep three copies of your files on two different media (cloud storage and an external hard drive), with at least one copy stored off-site.
Automated backup methods:
- Automatic cloud synchronization: Set up services like Google Photos, iCloud, or OneDrive to upload your images as soon as you connect to a Wi-Fi network.
- Periodic local storage backups: Download your photos to an external hard drive or SSD at least once a month.
- Integrity verification: Periodically check that the saved files open correctly and are not corrupted.
