Digital data preservation involves planning and allocating resources to ensure digital information remains accessible and usable over time. It requires policies, strategies and preservation methods to ensure future access. The document outlines 13 ways to approach digital preservation, including as an ongoing activity that avoids crises through continuous effort rather than periodic bursts; as a cooperative effort across organizations to enhance funding; and as a selection process to determine what data is worth preserving given limits on storage. The conclusion notes that while the article outlines preservation approaches, it does not explain how to achieve preservation or select essential data to retain.

Data Preservation

2. Why Preserve data?

3. Communication

4. Finance
 Finance :- How we get money anytime or anywhere in
the world won’t happen. The average cost of
transaction using an online or mobile devise is 56
cents, 59 cents at an ATM, compared to $3.97 with a
bank teller.

5. Weather Forecasting

6. Ecommerce & Logistic

7. Social Media & Entertainment
 Social Media:- Online
networks can’t share over 500
million tweets, 70 million
Instagram photos.
 Entertainment:- Worldwide
903.3 million pay-tv
subscriber will loose access.
Pandora Listeners won’t hear
a total of 55.8 million hours of
streaming music.

8. What is digital
preservation?

9. Digital Preservation
Digital preservation is a formal endeavor to ensure
that digital information remains accessible and usable.
It involves planning,
resource allocation, and
application of preservation
methods and technologies,
and it combines policies,
strategies and actions to
ensure access to data. In
short it ensures we can
access data tomorrow.

10. How to preserve
Digital Data?

11. As an ongoing activity
Preservation traditionally proceeds in fits and starts, with
extended periods of inactivity punctuated by bursts of
intensive effort.
It follows the pattern in which materials are left to
approach a state of crisis, at which point the situation is
remedied through large-scale intervention.

12. As a set of agreed outcome
It is one thing to recognize that
actions must be taken to secure
the long-term persistence of digital
materials; it is another to articulate
precisely what the outcome of
preservation should be.

13. As an understood responsibilty
As digital preservation is a
continuous activity, so its
responsibility should extend
beyond traditional stewards.
Preservation considerations must
be taken into account at the time of
a digital object's creation.

14. As a selection process
1. Collect as many digital materials as
possible and deposit them into mass
storage systems
2. Select, which digital materials should
be preserved and taking steps to
curate them throughout their
lifecycle
Digital preservation is expensive and it is impossible to
store all the information digitally. We have 2 options.

15. As an economically
sustainable activity
Two key economic challenges plague efforts to preserve digital materials.
1. Allocation of funds to digital preservation has been insufficient.
2. Funds are usually provided on a temporary basis, often as grants to
support one-off undertakings or special projects.

16. As a Cooperative Effort
Digital preservation is expensive, funding is scarce, and
preservation responsibilities are diffused
Corporation could help digital preservation activities
achieve its goals.
Cooperation can enhance the productive capacity of
digital preservation funds.

17. As an innocuous Activity
 The archiving agency have to alter the archived content in
some way
 Appropriate permissions must be obtained from the rights
holders.

18. As an aggregated or
disaggregated service
Includes hardware, software, and network infrastructure supporting the storage
and distribution of digital content.
Specialized services to manage the archived content, including metadata
creation and management, and validation of materials' authenticity or integrity.
Preservation layer , monitors and administers the changes related to access
and migration
Services that support browsing or searching, access requests, validating
access permissions, and arranging for delivery.
A digital preservation system can be deconstructed into several
functional layers.

19. A compliment to other library
service
Digital repositories
will function not
just as guarantors
of the long-term
viability of
materials in their
custody, but also
as access
gateways.
Fulfilling this dual
mission requires
that preservation
processes operate
seamlessly
alongside access
services.
Careful records of
the outcome of
preservation
processes must
be kept

20. A well understood process
There is as yet little consensus on best
practice for carrying out the long-term
preservation of digital materials. suitable
benchmarks and evaluative procedures for
assessing the outcomes of digital
preservation processes.
Prospects for cultivating a shared view on this
issue hinge on three factors: identification and
development of standards to support digital
preservation; and mechanisms for certifying
adherence to a minimum set of practices on the
part of digital repositories.

21. An arm’s length transaction
 A related question concerns what is supplied in
exchange for payment.
 What preservation guarantees can the digital
repository offer?
 To what compensation is the depositor entitled if
promised outcomes are not achieved?
 Resolution of these issues must emerge from a
convergence of customer expectations and repository
commitments.

22. One of many options
 Selection between analog and digital
preservation should not be cost comparison
but take users preference into account.
 Librarians discovered some time ago that
users were resistant to replacing paper
publications such as newspapers and
magazines with microfilm copies,
 In the same way, users may prefer that certain
information resources be preserved as analog
objects, and others as digital objects.

23. A Public good
Preserving information resource is not
only beneficial to its owner.
An institution that preserves the last copy
of a resource has performed a service of
potentially incalculable value to the
public
In these circumstances, the benefits from
preservation are widely distributed;
unfortunately, the costs of preservation
are not.

24. Conclusion
Though the article illustrates some very nice ways
of preserving data , it is not absolutely right in the
present context due to the timeframe in which
article was written.
Article emphasizes on the ways of preserving the
data but doesn’t tell how can we achieve data
preservation nor he presents ways of segregating
required data as oppose to available data.
Digital data preservation should be given more
importance at the same time , we should try to find
ways of accessing universal data at the same time
managing access rights.
