Extract text from backup archives and disk images (NBZ)
To convert NBZ archives to another format, you need Nero BackItUp or other Backup software.
To convert other file formats to the "Compressed Backup Archive" file type, you need software like Nero BackItUp or a similar tool.
An .NBZ file serves two entirely different technological niches. For the average PC user, it is a proprietary, compressed backup archive created by data protection software like Nero BackItUp or the now-obsolete ArcSoft TotalMedia Backup & Record. In the vintage computing and preservation community, an .NBZ file is a compressed "Nibble" disk image created by the nibread utility. It stores the raw, bit-level magnetic flux transitions of Commodore 64 floppy disks to preserve copy-protected software.
The main disadvantage of .NBZ backup files is vendor lock-in. Your personal photos, documents, and system states are trapped in a closed ecosystem. If your subscription expires, you uninstall the software, or you switch to a macOS or Linux computer, you lose access to your own data. For retro enthusiasts, the raw bitstream stored in an .NBZ file includes intentionally corrupted, non-standard GCR-encoded bits. Because of this extreme precision, modern standard emulators like VICE cannot run the games directly.
To regain control of your files, you must extract the .NBZ backup and convert the container to an open, universally supported archive format like ZIP or TAR. This guarantees long-term accessibility without relying on legacy software. If you have a C64 .NBZ image, you need to use a tool like nibconv to convert it into a standard G64 or D64 file, which strips away unnecessary raw flux data and makes it playable.
Because .NBZ files are either heavily proprietary or contain raw hardware bitstreams, standard online file converters will fail to process them. We will analyze the internal file signatures to determine whether you have a backup archive or a retro disk image. If our analysis detects a supported underlying compression method, viewing the internal contents or extracting the files may still be possible without reinstalling outdated software.
Convert.Guru analyzes your NBZ file, detects the exact format, and lets you read the text inside.
Users also converted NZB, NEF and ZIP files.
If you want to convert NBZ file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Nero BackItUp or similar software from the "Proprietary Backup & Disk Imaging" 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 NBZ, try Nero BackItUp or another comparable tool in the "Proprietary Backup & Disk Imaging" 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 NBZ converter.
