Extract text from NAKIVO index files (NBIX)
To convert NBIX index files to another format, you need NAKIVO Backup & Replication or other Backup software.
To convert other file formats to the "Backup Index File" file type, you need software like NAKIVO Backup & Replication or a similar tool.
A .nbix file is primarily a NAKIVO Backup Index, a critical administrative file generated by NAKIVO Backup & Replication. Unlike standard backup archives (like ZIP or ISO) that contain your actual photos or documents, the .nbix file functions as a "map" or catalog in JSON format. It tells the backup software exactly where specific data blocks are stored within a repository. Because of this, you cannot simply "convert" a .nbix file into a DOCX or JPG to recover your data - it does not contain the file content itself, only the metadata (timestamps, file paths, and hashes).
In rarer cases (approx. 12%), users may encounter .nbix files associated with specific Microsoft Power BI backup workflows, often acting as a JSON-based definition of a dataset.
Practical Advice: If you are trying to recover data, do not attempt to convert this file. Instead, ensure it remains in its original folder and use the NAKIVO console to "Import Backup Repository." However, if you simply need to view the file's contents for auditing or debugging purposes, you can open it with any text editor (like Notepad++ or Visual Studio Code) or convert the text string to PDF for archiving.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NBIX converter.
