File type: dBASE Database Backup File
File Extension DBK
The DBK file extension supports the backup functionality of the dBASE RDBMS software. This file format represents the backup file created from the database file (either a DBF or a DB2 file extension format) prepared by the user. The DBK file extension may be generated automatically by the dBASE application like in the case of the original database file becoming corrupted.
In the context of information technology, a backup file refers to the process of creating copies of the data files in order to generate additional copies which can be used for restoring the original state of the data after it its lost.
The backup file is only accessible to the program that created it. This essentially means that it is useless without its host application. However, there are instances wherein interoperability exists between certain programs under the same category allowing one application to import the backup file created by another program.
In database management, a database file backup essentially contains the same information and structure as the original but in a compressed form which makes it unreadable by the program unless it is first extracted.
