Abstract
A data storage device and method for preventing accidental updates and deletions using data versioning are provided. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to: receive a command from a host to modify data stored in the memory, wherein the data is associated with a host identifier created by the data storage device; determine whether the host is associated with the host identifier; in response to determining that the host is associated with the host identifier, modify the data; and in response to determining that the host is not associated with the host identifier, create a new version of the data without modifying the data. Other embodiments are provided.
