Extract text from Comodo backup files (CBU)
To convert CBU backups to another format, you need Comodo Backup or other Backup software.
To convert other file formats to the "Proprietary Backup Archive" file type, you need software like Comodo Backup or a similar tool.
The .CBU file extension is primarily used as a backup archive created by Comodo Backup. It can also function as an encrypted device update file for hardware like Compute Box or Eye Box, and is occasionally associated with backup tasks from Cobian Backup or Acronis True Image. These files securely store compressed copies of a user's documents, system settings, or entire disk partitions.
Users often attempt to convert .CBU files to standard archive formats like ZIP or 7Z. The common goal is to quickly extract photos or documents without downloading, installing, and configuring legacy backup software. The primary disadvantage of the .CBU format is its proprietary structure. It locks your essential data inside a closed ecosystem. If you switch to macOS or Linux, or if the original software is discontinued, you lose native access to your files. Furthermore, these archives are frequently encrypted and can exceed hundreds of gigabytes, making them completely unreadable by modern web browsers or standard file explorers.
Standard online file converters usually fail to process .CBU files. This is because only the original backup software contains the specific algorithms required to decrypt, decompress, and correctly rebuild the internal directory tree. To securely transition away from this format, you generally must restore the backup using the original application and then manually re-compress your files into universal, open targets like ZIP or TAR.
Despite these strict limitations, just drag and drop your file to convert.guru to see what it is and convert it if supported. Our platform will perform a deep technical inspection of the file headers and hex data. If our analysis detects unencrypted text or an embedded standard container, viewing the internal content or extracting partial data may still be possible.
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.
If you want to convert CBU file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Comodo Backup or similar software from the "Data Backup Archive" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to CBU, try Comodo Backup or another comparable tool in the "Data Backup Archive" category.
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.
