destruction or damage on a catastrophic scale Usually a single
event.. What was the single event that changed the face of
technology forever? 2

Media (Medium) vs Format Medium - the way in which the content
is transferred The definition of media is the plural of medium, or
ways to communicate information. Format - how the content is
presented Medium is string and some cans Format is voice 6
Slide 7
Formats Over 17,000 different format being used You know

others?.cpio.shar.LBR.iso.mar.tar.bz2.gz.sfark.arj.dar.dgc 7
Slide 8
Formats Have Versions File formats are subject to rapid
obsolescence and evolution and the process of selection and
assessment of options for preservation is largely one of risk
reduction. PDF has issued more than 15 different iterations since
the early 90s But only promised 20 years of backwards compatibility
(which is more than most manufacturers). 8

Slide 11
Minimizing the Risks Use file formats which have been: Well
documented Undergone thorough testing Are non-proprietary Usable on
different hardware and software platforms This minimizes the
frequency of migration and reduces the risk and costs in their
preservation. 11
Slide 12
Widely Adopted Formats Utilize formats that have been widely
adopted: Minimizes risk as it is more likely that migration paths
will be provided by the manufacturers and a degree of "backward
compatibility" will be available between versions of the file
format as it evolves. It is important to note that backward
compatibility is rarely maintained for more than one or two
previous versions and that the "window of opportunity" to migrate
is therefore relatively brief. 12
Slide 13
Non-proprietary and Open Specs Non-proprietary, open
specificationsIn terms of guaranteed long-term availability,
published specifications produced by international standards bodies
are the safest. Generally, representatives from many different
constituencies are involved in creating the standard, helping to
ensure that it balances the needs of a wide variety of users and
that it isn't beholden to any particular commercial interest. Broad
participation also helps provide incentive for wide support once
the standard is completed. Backward compatibility with older,
related standards is usually a priority and there are no commercial
pressures for rapid obsolescence. One of the most recent examples
of this is the standardization of the OpenDocument Format (ODF) as
an open source format. ODF stemmed from the open XML-based
OpenOffice.org specification and was approved by ISO as a standard
in 2006.

How Do We Deal With The Media? It will eventually be replaced
with new media It can be really small It can also be really big It
can hold tons of data in all format It allows for ease of transfer
Can allow for long term storage (think microfilm) It can be fragile

Slide 20
Pay Attention You need to do an inventory of what media exists
in your organization Check 1 st with IT to see if a data map has
already been generated it should contain the types of media Are
there restrictions on the use of external media in your
organization? Is there a migration plan in place for the data kept
on the media? 20
Slide 21
Doing An Inventory If you have done an inventory of your
records within the organization then you should have captured at
the same time the location of the records e.g. if it exists on
external media If not, then ask the content owners to identify
where their records actually reside make sure they look for
external media 21
Slide 22
After The Inventory Once you have the inventory of what exists:
1. Make sure you have identified the individual types of medium 2.
Determine what type of data exists on the medium 3. If possible
determine the formats that exist on the medium (including version)
4. Who owns the data (office of record)? 5. Are there records or
copies of records on the medium? 22
Slide 23
If IT Has Inherited Old Media Often old media is left over from
departing staff, reorganizations, changes in management, etc. If no
one is around who has an idea about the content on the media, then
you must do an sampling of the data. Usually 3% is sufficient. The
best way is to find staff with corporate memory who can help with
identification of the data. 23
Slide 24
So Why Do You Care About Contents On Old Medium? Because it may
hold information of value: Official Records Personal Information
(PII) Classified Data It might be the only copy of the original
drawing for the engineering project back in 1993. 24
Slide 25
Chances Are The Contents Are Copies If the volume is large you
may have to do a risk assessment to determine the ROI on
ascertaining the contents before destruction. If you no longer have
the hardware/software to read the data on the old media then you
may have no choice but to destroy the media and its contents. 1 st
Notify staff that this media is being destroyed unless someone
knows the content and reason to keep it. Prior to destruction
document to the best of your ability the medium, the capture any
metadata that may exist on the medium. 25
Slide 26
Create the Record Explain what media was found & how much
(video tapes on VHS- 15 in a box) Document where it was located (in
back storage room in the IT department, with no climate control) If
there are dates anywhere, capture them (1976-1985 written on the
case) Copy all metadata available about the possible content (site
visit by Colonel Mustard) Document efforts to obtain information
about content (put out a broadcast email seeking information)
Document the destruction date and by whom 26
Slide 27
How To Avoid This Scenario Know what medium exists in your
organization Keep track of it Have policy and procedure in place
for the use of external media Make sure IT has a procedure for not
allowing old medium to rot on the shelf and become obsolete 27
Slide 28
Have A Migration Policy Have a policy in your organization that
makes individuals who store data and records outside of the live
system responsible for the migration to newer medium. Do no allow
the use of external storage devices in the organization (good luck
with this one) Have health check/migration plan in place for older
media (the boxes of microfilm that no one looks at) 28
Slide 29
Best Risk Avoidance Keep the data alive on an active system
that is being maintained by IT Reduces risk to the data and records
Cuts costs of maintaining old medium 29
