Online backup software helps individuals and businesses protect important files by storing copies in the cloud. If a device is lost, damaged, stolen, infected by malware, or accidentally deleted, a backup solution makes it easier to restore data and continue working.
The best online backup software should offer secure storage, automatic backup, file recovery, version history, device protection, and simple access across devices.
