What is AXF?
• AXF is a fully self-contained, self-describing file storage container
– think of it as advanced “ZIP”
• AXF does not overlap with MXF or other “media wrapper”
approaches as these are simply files inside an AXF Object
• AXF is based on an innovative “file system per object” approach
which fully abstracts the underlying operating system, storage
technology and file system
• Standard support for all storage technologies – now and into the
future!

AXF and Storage
AXF is Storage Technology, Operating System and File System Agnostic.
It can store objects to various storage technologies, formats and devices

AXF Technology
• AXF Objects can scale to any size and encapsulate any number of
files with full support for media spanning
• No need to upgrade existing systems as AXF does not rely on
modern tape functionality such as partitioning
• AXF guarantees long term compatibility and resiliency with self-
describing features for both AXF Objects and AXF Media
• AXF is an IT-centric implementation and is not limited to media files
alone (metadata, documents, image files, etc.)
8Migrate Manage Market Lynx
What About TAR?
• Tape ARchive (TAR) format has been around for many decades
• Despite following established standards there is no true
“standard” TAR implementation
• TAR is an archaic format which cripples the core value of the
CSM solution as it does not allow timecode based partial restore,
etc.
• TAR does violate most of our key storage goals (e.g. Open
Archival Information System features such as fixity, provenance,
reference, no resiliency features, etc.)
9Migrate Manage Market Lynx
What About LTFS?
• The Linear Tape File System (LTFS) is basically that…a simple file system for linear data tape
• LTFS relies on modern data tape partitioning functionality and makes data tapes appear as “removable USB drives”
• LTFS does not offer preservation features such as those defined in the OAIS model
• There are no standards bodies which endorse LTFS
• Useful for the physical “transport” of file based content as a video tape replacement but not for long term storage or preservation
10Migrate Manage Market Lynx
Key LTFS Limitations
• LTFS has no concept of media encapsulation forcing users to rely
on rudimentary folder hierarchies to form important asset
relationships and context
• LTFS cannot scale as it has no support for spanning across storage
media limiting file collection sizes
• LTFS is a data tape based technology which does not apply to disk
or other storage formats – not universal!
• Unfortunately neither LTFS nor TAR help us realize our long term
storage and preservation goals

AXF? LTFS? Both?
• Despite many limitations, LTFS does have a valid place as a file
based asset transport mechanism.
• LTFS can be used to move assets between remote systems and
advanced Content Storage Management (CSM) solutions such as Front Porch Digital’s DIVArchive system but it is not viable as a
long-term archive technology.
• DIVArchive leverages the Archive eXchange Format – or AXF – to
ensure long-term accessibility, transportability, protection and preservation of your most valuable assets.
