When a Samsung DVR (such as a CCTV recording system) saves a video recording, it generates both a .BU and a DB2 file. The BU file contains the actual video data, while the DB2 file contains metadata about the video. The two files are saved in the same directory and should not be separated.

Since BU and DB2 files are saved in a proprietary format, they cannot be played back by most video players. Instead, these files are only recognized by Samsung hardware and software.
