Extract text from CBU files
To convert your CBU file to another format, you need Comodo Backup or other Backup software.
To convert other file formats to the "Backup Archive" file type, you need software like Comodo Backup or a similar tool.
A .CBU file is primarily a proprietary backup archive created by Comodo Backup. These files function as secure containers for your user data - bundling documents, photos, emails, and system registry keys into a single compressed entity.
Users typically encounter .CBU files when attempting to restore legacy data or when migrating to a new backup solution like Acronis Cyber Protect Home Office (formerly True Image). The real problem is the proprietary lock-in: .CBU files cannot be opened by standard archivers like WinRAR or Windows Explorer without the original host software. Additionally, high-security environments often use .CBU for encrypted device updates (e.g., Compute Box firmware), which are strictly read-only and cannot be converted.
For general data recovery, the best "conversion" is extraction. By reinstalling Comodo Backup or occasionally renaming the extension to ZIP, users can extract the contents to standard formats like DOCX, PDF, or JPG for editing, web use, and archiving.
Convert.Guru analyzes your CBU file, detects the exact format, and lets you read the text inside.
Users also converted ACR, FILEXT and KML files.
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 CBU converter.
