The 100 Year Archive Task
Force has several projects underway in which you can participate:
a. Help collect business
requirements for long term retention by taking the online "Business
and IT Requirements survey". We also need assistance in spreading
the word. Forward this link to your 'customer' colleagues.
Register here to receive the final
b. We're currently reviewing a
glossary of terms for inclusion in the "100 Year Archive Best Practices
Guidelines" and SNIA dictionary. Please contribute. The working document
is posted in the members area in the 100 Year Archive Task Force portal.
We invite you to join us on our
conference calls as we progress the work. Bi-monthly on Thursday at 3-4
PM ET. Dial 712-580-0600 - passcode 961226#.
Then, Join the DMF and
For more information, please

We look forward to working with you!
The SNIA’s 100 Year Archive Task Force is a global, multi-agency group
working to define best practices and storage standards for long term
digital information retention. All interested parties and organizations
are invited to join in this work effort.
- Produce with a multi-disciplinary team a “best
practices for long term digital information retention” paper similar to
the Sedona project
- Influence ILM as a core management and automation
practice for long term archive
- Guide the impact of new storage technologies such as
XAM & Grid to improve long term retention methods
- Define a standard for on-media formats & long term
Are you a vendor, integrator or service
provider involved in long-term archiving, or a governmental, RIM, IT, or
regulatory compliance responsible professional? Join us and help shape industry
standards and best practices as we define storage solutions to the challenges
of long-term digital information retention. Our charter includes educating
customers so we also have an active speaker's bureau which you can
access or participate in.
Although corporate and
legal issues have recently brought data archiving to the light of day, the
problems associated with preserving digital information are not new.
Archiving for a few years is hard enough, but when requirements dictate that
data be retained for longer, problems with media deterioration and
technology obsolescence can seem insurmountable.

Corporate archiving systems tend to be
very reliant on older servers and tape backup systems, both of which degrade with age. While the technology does exist to recovery drives and backup tape in clean room environments, hard drive recovery services are always considered an afterthought to most companies. This has to change, as companies discover the mortality of their backup media.

Long term preservation
of digital content is a big challenge in the Information Society era,
digital information in any form is at risk to be lost forever. Technology on
which digital content relies becomes obsolete and application versions and
files formats change, making data soon inaccessible. Even if content is
coded in the simplest format, such as ASCII code, storage media degradation
and obsolescence could make it disappear. Even on-line information such as
web pages and databases, are vulnerable as much as their web structure
become complex thanks to (aging) hyperlinks and cross references.

What is the state of best practices today?
says if information is on disk drives, migrate it every 3 years and if on
tape, every 5 years. But, what about the ability to read and interpret the
Physically, long-term storage is
not about media life (because migration is required) but, about periodic
migration to newer media. But, how do you migrate a PB every year? At
some point migration becomes overwhelming.
Logically, long-term retention is
about the ability to read the information and to be able to use it.
Applications have relatively short life and rarely have the ability to read
information older than a few revisions. While RAID arrays have helped provide a layer of security, these systems do fail, and prices for RAID recovery can be quite high. Even standard formats evolve,
change, and become obsolete. At some point, information has to be migrated
periodically to a new standard logical format.
Then what about issues such as
compliance, integrity, and authenticity? How are you guaranteeing these over
the retention period?
