UNITEX Announces Major Version Upgrade of "UNITEX ArchiveLT,"
an Archive Software for Windows Featuring Proprietary LTFS Software
Unitex Co., Ltd., a provider of LTO data storage solutions, will launch "UNITEX ArchiveLT Ver. 2.0.0" in June 2025. This Windows-based archive software maximizes device performance for large-scale data storage and management and now includes proprietary LTFS (Linear Tape File System)* software.
*LTFS (Linear Tape File System) is a feature that enables data stored on magnetic tape to be managed on a file-by-file basis, just like data on HDDs or USB drives.
[Product Overview]
UNITEX ArchiveLT is an archive software solution widely used across various industries both domestically and internationally. It enables high-speed archiving and retrieval of large-scale data to and from LTO tapes, ensuring safe long-term storage. Additionally, it features a proprietary database for powerful offline search and management capabilities.
With this version upgrade, Unitex has developed proprietary LTFS software that allows LTO tapes to be displayed as drives in Windows Explorer, enabling them to be managed similarly to HDDs or USB drives. This enhancement ensures compatibility with new operating systems and future LTO standards, improving usability and flexibility.
Furthermore, UNITEX ArchiveLT is now available in a license edition system (Standard/Enterprise) tailored to different use cases and system scales. This makes the software accessible to a broader range of users, whether they are utilizing single LTO drives or LTO library devices.

[UNITEX ArchiveLT Ver.2.0.0 Upgrade Points and Features]
Integration of LTFS Software
Previously, the software required for LTFS was separate. However, with this version upgrade, Unitex has integrated its proprietary "UNITEX LTFS" into UNITEX ArchiveLT. As a result, all features, including LTFS functionality, are now provided within UNITEX ArchiveLT.<Key Features and Improvements of "UNITEX LTFS" Integrated into UNITEX ArchiveLT Ver.2.0.0>
- LTFS Integrated into Windows
When an LTO tape formatted with LTFS is loaded into an LTO drive, it is automatically recognized and displayed as a drive in Windows Explorer, just like an HDD or USB memory. Users can perform read/write operations via drag-and-drop or copy files using the COPY command. - Rollback Functionality
LTFS is an append-only file system, meaning that even if files are deleted or overwritten, the data on the LTO tape remains intact, with changes appended to reflect logical updates. The rollback feature allows users to revert to a specific point in time. This ensures that files can be recovered even in cases of accidental deletion or modifications caused by ransomware. - Seamless Drive Letter Assignment
The drive letter is assigned after the LTO tape mounting process is completed in the background. This resolves issues in previous LTFS software where tools like Explorer became temporarily unresponsive during the mounting process. - Smooth LTO Tape Ejection
By handling tape ejection as a background process, the issue of Explorer and similar tools becoming temporarily unresponsive during tape ejection has been resolved. - Automatic Tape Ejection During Shutdown
When the PC is shut down or restarted with an LTO tape mounted, the software automatically unmounts the tape and ejects it. - Compatibility with Existing LTFS LTO Tapes
The software is compatible with LTFS LTO tapes created using previous software, enabling users to read previously recorded data or add new data to those tapes. Additionally, data written with "UNITEX LTFS" can also be read by other LTFS-compatible software. - Resolution of Windows Security Update Issues
The issue in previous software where applying Windows security updates restricted file copy operations in Explorer has been resolved.

Moreover, the SONY ODA integration feature allows seamless data migration between SONY's Optical Disc Archive and LTO.*A list of verified drives will be provided.
Cloud Integration Function
Compatible with the Latest Windows Server 2025
The software has been tested and verified to operate in the Windows Server 2025 environment.Support for LTO Library Devices
By combining UNITEX ArchiveLT Ver.2.0.0 with tape autoloaders or library devices, users can achieve highly convenient, flexible, and secure large-scale data management. Archived file information is stored in a database, allowing easy search and retrieval of necessary data from all LTO tapes within the library. Furthermore, simply specifying the source data and the destination tape enables automatic LTO drive selection and tape transport, even in environments with mixed LTO generations.Other Features
- Incremental Archive Function: Manages archive generations by archiving only files that have been updated or added since the previous generation.
- TAR Tape Archive Function: Enables data storage and management on LTO tapes in TAR format.
- Folder Monitoring and Scheduling Function: Automatically archives data when a monitored folder exceeds a specified capacity or according to a predefined schedule.
- Compliance with JIS Z 6019: UNITEX ArchiveLT meets the highest safety guarantee level (Level 3) for long-term storage as defined by the JIS standard "JIS Z 6019" for digital information storage on magnetic tapes. This includes byte-level comparison of individual files, ensuring secure and reliable long-term preservation of critical data.
