What is the best way to back up a Windows PC?
The low-effort gold standard: a cloud backup service (Backblaze or IDrive) running continuously, plus File History to an external drive for fast local restores. Want to restore Windows itself after a disk failure? Add disk-image backups with Acronis or the built-in tools.
Windows backup has two distinct jobs that people conflate. Job one is files: documents, photos, projects. Cloud backup handles this best because it is off-site (fire, theft, and ransomware cannot reach it) and automatic; Backblaze covers everything on the machine for one flat price, IDrive does the same across several devices. Pair it with Windows File History writing to a cheap external drive and you get instant local restores for the everyday "I overwrote that file" moments.
Job two is the system: Windows, programs, settings. After a dead SSD, file backup alone means a day of reinstalling. Disk-image backup photographs the entire drive so you can restore the whole machine to a new disk; Acronis is the consumer standard (with cloud or local destinations), and Windows' built-in system image plus a recovery USB is the free, clunkier route. For most home users, images monthly plus files continuously is the right rhythm.
The combination sounds heavy and is not: one evening of setup, then it runs itself. What turns a disk failure from disaster into errand is not any single product but the layering, which is exactly what the 3-2-1 rule formalizes.
