Windows 10 and 11 PCs don't support the Windows NT data. So, you won't be able to access its data backup stored on an LTO tape. You will need to use a specialized tape data recovery software to recover inaccessible data backups from a magnetic tape cartridge.
Not many users use the Windows NT backup utility now, as it has become obsolete. Yet, there are some users on the internet looking for a way to access their data archived on old LTO tapes using this discontinued backup utility.
As the archives on the tape are written using a utility that is not supported on modern Windows OS (Windows 10 or 11), they become unreadable or inaccessible. So, if you are one of the few users trying to access data on such tapes, then this article is for you. Here, you'll find out a way to read the NT Backup tapes on existing OS and recover inaccessible data from the tapes using a specialized LTO tape data recovery software.
What is Windows NT Backup?
Windows NT Backup is a backup utility introduced in 1993 with Windows NT 3.51. It was made available as both a GUI-based utility and a command-line utility called "ntbackup". Using either of the utilities, users can create and manage data backups in different storage media. It stored data backups in BKF format on floppy and zip drives, and in MTF format on magnetic LTO tapes.
The "ntbackup" command was an alternative way to start the backup utility. It was used via the Command Prompt to create and restore backups.
It used two features to make the backup process efficient – Shadow Copy to create data backups and Task Scheduler to schedule them.

There are, however, other reasons as well, which could make the Windows NT backup on LTO tapes inaccessible:
- Backup configuration issues
- Missing catalog files
- Incompatibility between the tape cartridge and the drive
- Incorrect leader pin position
- Improper connections between the LTO tape drive and the host system
