Backing Up Your Files & Photos

Phones get lost, laptops get stolen, hard drives fail and ransomware locks files. A backup is a separate copy of your important files that lets you recover. Most people only think about backups after they’ve lost something they can’t replace.

The 3-2-1 backup rule: three copies, two types of storage, one off-site.

For ransomware protection, keep at least one backup disconnected or in a cloud service with version history, so infected files can’t overwrite it. See Ransomware.

A backup you can’t restore isn’t a backup. Every few months, try restoring a file or folder to make sure it works.
