Backup and Recovery Software

This group holds two related but distinct kinds of tool, and it helps to separate them. Backup software copies your data on a schedule so a failure costs you nothing. Recovery software is what you reach for after a failure — when a drive has died, a partition is gone, or files were deleted before any backup existed.

On the backup side, the choice is usually between file backup and disk imaging. File backup copies documents and folders you select. Imaging captures the whole drive, operating system included, so you can restore a machine to exactly its previous state. Many suites do both, and the right mode depends on whether you are protecting documents or a full system setup.

Recovery tools work differently. Programs of this type scan a drive for data the file system no longer references and try to reassemble it. Their success depends heavily on one thing: how much the drive has been written to since the loss. The sooner you stop using a disk after deleting something important, the better the odds of getting it back.

A practical habit beats any single program. Keep more than one copy, on more than one device, with at least one copy away from the original — a routine often summarized as three-two-one. Software automates it, but the discipline of checking that a backup actually restores is what saves you when the day comes.
