The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
.bak, .bk – Bak file various backup formats: some just copies of data files, some in application-specific data backup formats, some formats for general file backup programs BIN – binary data, often memory dumps of executable code or data to be re-used by the same software that originated it
