File backup, cloud sync, and full disk imaging software
10 programs reviewed · Updated August 9, 2026
Backup software exists for one reason: to make data loss recoverable. The distinction that matters most is between file-level backup, which copies selected files and folders, and disk imaging, which captures an entire drive byte-for-byte so a failed system can be restored exactly as it was, including the operating system and installed programs.
The 3-2-1 rule is still the most reliable general guidance: keep at least three copies of important data, on two different types of storage, with at least one copy off-site. A cloud backup alone protects against a failed local drive; a local backup alone doesn't protect against fire, theft, or ransomware that encrypts everything it can reach.
This hub covers file backup tools, disk imaging software, and cloud sync services, along with guides for recurring tasks such as restoring a system from an image, scheduling automatic backups, and verifying that a backup actually works before you need it.

Sync keeps a folder identical across devices in near real time, including deletions — which means a ransomware attack or accidental deletion can propagate to every synced copy. Backup keeps separate historical versions, so you can recover a file as it existed before something went wrong.
File backup protects your documents and photos, but a disk image lets you restore your entire system — OS, installed programs, and settings — after a drive failure, without reinstalling everything from scratch.
Periodically restoring a sample file or, for disk images, doing a full test restore to spare hardware is the only way to know a backup actually works rather than assuming it does.
