New in Version 6.1


Enhanced LTFS support with P5 Archive

With the release of version 6.1, Archiware has created an entirely new cross-platform LTFS driver that brings features and convenience not seen before with LTFS software products. Archiware's new approach removes the need for the open-source 'FUSE' software used by competitive products, allowing direct control of the tape media, while maintaining full ISO/IEC compatibility.

LTFS formatted LTO tapes are now supported by the P5 Archive module. Users wishing to archive data to tape, with full indexing, searching, thumbnail generation and meta-data ingest, can now choose between two different tape formats:

P5 volume format

  • Supported for 20 years across thousands of P5 installations, compatibility across all P5 supported platforms, support for block-level cloning, parallel writing across multiple tape drives, data-compression/encryption and free from character set limitations for file/folder names.

LTFS volume format 

  • Open standard (ISO/IEC 20919:2016) and manufacturer-independent tape format, compatible across all P5 supported platforms (macOS, Windows, Linux, FreeBSD) and also with other LTFS software tools for software-independent restore of data.
Native LTFS Support Padded

LTFS formatted LTO tapes are now supported by the P5 Archive module.

Both formats support spanning of large files across tapes. When a storage pool is created for archiving, there is now an option to choose between the 'P5 Native' and LTFS formats. Volumes can be formatted as LTFS by labelling, in single drives or libraries.

Existing native pools and LTO volumes will continue to work in combination with LTFS volumes. LTFS is a useful option where interoperability with non-Archiware systems is required.

Important Note: The LTFS Import/Export feature, which is independent of the new LTFS functionality described above, is supported only on macOS and Linux in the 6.1.0 release.


The desktop application for macOS, Windows and Linux is updated to support archiving of individual files, selectable archive plan from drop-down menu, and various UI tweaks to make it easier to use.

For users of the P5 Archive App (now discontinued), the P5 Companion now supports stub files created by this application and can restore them.

Poster-frame for video previews

  • P5 Archive will now automatically capture a poster-frame thumbnail when archiving video files, using FFmpeg. The poster frame will be displayed in the grid/thumbnail view and upon double-clicking, the video proxy itself can be played back.

Built-in FFmpeg & ImageMagick

  • A P5 installation now includes both of these open-source tools for creation of video and graphic previews, manual download and installation of these open-source tools is no longer required. If a custom installation is required, including plug-ins or extensions, an external installation can be performed and used by P5.

Merge multiple source folders into one destination folder

For ease of organising the layout of multiple source folders copied to a single target directory within a single Sync plan. It is now possible to specify how much of the original source path is created in the target directory.

This is achieved by including a dot in the source path. Creating multiple Sync plans to achieve this is no longer required. The default behaviour does not change, which is to append the entire source path at the target location.

For example, take these two data folders:


If we sync both to the target destination folder:


We would see these two folders created at the destination:


In 6.1, the inclusion of a dot in the path gives more explicit control. For example if we modify the source folders in the sync plan (not on the filesystem) as follows and sync to the same location:


Then we would see these folders created at the destination. The path elements before the dot are excluded at the destination:


This advanced option could be used with care to avoid directories 'colliding' at the target. Source paths with and without dots can be combined within the same sync plan if needed.

Checksum Verification

A crucial feature for media customers who require maximum data security and accuracy, a checksum is automatically created while reading each file from the source, and also whilst writing to the destination.

These are verified to match. The checksum is also stored as an extended attribute within the destination file, for interrogation by other workflow tools, if needed.

Updating P5 in the browser

P5 software updates can now be installed directly from the web-admin interface on macOS and Linux installations. This is particularly useful for remote systems, such as Amazon EC2 instances, where updating can be complex. A simple click checks for newer versions on Archiware's servers, downloads and installs and restarts.

This update feature is provided only for platforms that do not maintain their own software registry that includes P5. Both Windows and NAS systems such as QNAP, Synology and ReadyNAS include their own package manager.

Optimized volume management for cloud storage

Storage management of the staging areas has been optimized. The storage size of the staging area can be considerably smaller, since the chunks necessary for the restore are deleted immediately after use.
