Convert CBK to CDB

Understanding cbk and cdb file formats

CBK files are typically backup files created by various software applications, such as Compressed Backup files or specific database backup formats. The exact structure of a CBK file depends on the originating software, but they are generally used to store backup copies of data for restoration purposes.

CDB files refer to Constant Database files, a fast and reliable key-value store format developed by Daniel J. Bernstein. CDB files are commonly used for storing small databases, configuration data, or lookup tables in a compact, read-only format.

How to convert cbk to cdb

Direct conversion from CBK to CDB is not always straightforward, as CBK files may contain data in a proprietary or compressed format. The process generally involves extracting the data from the CBK backup and then importing or converting it into a CDB database structure.

Step-by-step conversion process

1. Identify the source application: Determine which software created the CBK file. This is crucial, as you may need the original application to restore or extract the data.
2. Extract data from CBK: Use the original software or a compatible tool to restore or extract the contents of the CBK file to a readable format (such as CSV, TXT, or a database dump).
3. Prepare data for CDB: Format the extracted data as key-value pairs, as required by the CDB format. This may involve scripting or using a text editor to structure the data appropriately.
4. Create the CDB file: Use a CDB creation tool, such as cdbmake (part of the tinycdb or djbdns utilities), to generate the CDB file from your prepared data.

Recommended software for cbk to cdb conversion

• Original application: Use the software that created the CBK file to extract or restore the data.
• tinycdb or djbdns utilities: These provide the cdbmake tool for creating CDB files from key-value text files.
• Custom scripts: For automation, you can use Python or shell scripts to process and format the data before conversion.

Example conversion workflow

1. Open the original application and use File → Restore or File → Extract to get the data from the CBK file.
2. Format the extracted data into key-value pairs in a text file (one pair per line, separated by a null character).
3. Run cdbmake to generate the CDB file:
   cdbmake output.cdb output.tmp < input.txt

Summary

Converting a CBK backup file to a CDB database requires extracting the data from the backup and then using a CDB creation tool to build the new file. The process may vary depending on the source of the CBK file, but tinycdb and djbdns utilities are reliable choices for creating CDB files.
