For everyone Are your important photos and documents backed up, ideally automatically?
Why it matters: A backup is a separate copy of your photos and documents. If a device is lost, broken or locked by ransomware, the backup lets you get them back.
Yes No Not sure
How to do it Decide what matters most: photos, documents, messages, or the whole device. Choose where the copies go: a cloud service, an external drive, or both. Turn on automatic backup in the device or app settings where it's offered. Disconnect an external backup drive when it isn't in use, so malware on the computer can't reach it. Every so often, try restoring a file to check the backup works. Based on the ACSC's backups guidance, checked October 2026. The device questions in this checklist show the steps for each type of device.
