The value of data. (First in/First out).Though determining the monetary value of data is difficult and varies significantly based upon the business, knowing the relative value of data for a given business is a common practice. For example, the value of certain data, such as the Human Genome The human genome is the genome of Homo sapiens, which is composed of 24 distinct pairs of chromosomes (22 autosomal + X + Y) with a total of approximately 3 billion DNA base pairs containing an estimated 20,000–25,000 genes. project data, is basically indeterminable, since knowing the value derived from research and findings on this data is invaluable. What if the Human Genome data led to the cure for diseases or birth defects birth defects, abnormalities in physical or mental structure or function that are present at birth. They range from minor to seriously deforming or life-threatening. A major defect of some type occurs in approximately 3% of all births. ? Four distinct levels of classifying data exist. These levels indicate which backup and recovery technology may be suited and most cost-effective for level (See Figure 1). Critical data or mission-critical data is used in the key business processes and can account for up to 15% of stored online data. Losing access to this data means loss of revenues and risks the survival of the business. This data is best suited for disk mirroring or replication In database management, the ability to keep distributed databases synchronized by routinely copying the entire database or subsets of the database to other servers in the network. There are various replication methods. , as instantaneous in·stan·ta·ne·ous adj. 1. Occurring or completed without perceptible delay: Relief was instantaneous. 2. recovery is mandatory and is also backed up on tape to provide a copy of data prior to disruption disruption /dis·rup·tion/ (dis-rup´shun) a morphologic defect resulting from the extrinsic breakdown of, or interference with, a developmental process. . The mirrored disk copy and tape copies are often located at geographically distant locations from the primary copy. Critical data is normally classified as company secret. Vital data is used in normal business processes but doesn't mandate instantaneous recovery in order for the business to recover from a disaster or to remain in operation. Vital data is sometimes replicated and normally backed up using automated au·to·mate v. au·to·mat·ed, au·to·mat·ing, au·to·mates v.tr. 1. To convert to automatic operation: automate a factory. 2. tape libraries and is often classified as company secret. Sensitive data is used in normal business operations Business operations are those activities involved in the running of a business for the purpose of producing value for the stakeholders. Compare business processes. The outcome of business operations is the harvesting of value from assets and alternative sources for accessing or easily reconstructing the data exists in case of data loss. Sensitive data is not needed to provide minimal work levels in case of a disaster. Non-critical data represents the largest category of data and has relatively low security requirements and duplicate DUPLICATE. The double of anything. 2. It is usually applied to agreements, letters, receipts, and the like, when two originals are made of either of them. Each copy has the same effect. and aged copies often exist. Immediate recovery is not required. Lost, corrupted, or damaged data can be reconstructed re·con·struct tr.v. re·con·struct·ed, re·con·struct·ing, re·con·structs 1. To construct again; rebuild. 2. with minimal effort and cost. Email archives often fit this profile.
Data Classification Description
Mission Critical Up to 15% of online data, needed for
minimal work levels in the event of a
disaster. Normally mirrored/replicated
and backed to tape.
Vital About 20% of online data. Data used in
normal business processes but may not
be needed for a disaster recovery.
Normally backed up to tape.
Sensitive About 25% of online data. Data used in
normal business processes that has an
alternative source or can be
reconstructed. Normally backed to tape.
Non-critical Typically 40% of online data. Data that
is not needed for disaster recovery.
Easily reconstructed or duplicated
from prior backup copies.
