In
our modern corporate world, security of vital documents and data holds utmost
importance. Every company is measured on the basis of paperwork, i.e. shares,
debentures, properties and assets it owns and accounting of its primary
transactions. These papers need to be stored in such a way that the data
doesn’t get lost at any cost. But, disasters are basically uncertain and can
occur anytime without prior notice. Hence, to secure all the important data and
documents, businesses prefer maintaining the books of accounts in computers so
that the data can be stored safely and retrieved in case of any disaster.
Disaster Recovery is the process or a system which directs the
systematic procedure to get back the imperative data of organizations after the
firm faces a disaster. It is only concerned with IT field and has nothing to do
with physical papers or documents. Seeing the available disaster recovery options,
the majority of companies switches to the modern concept of data storage and
dump the idea of preserving paper-documents.
There
are three main control measures of disaster recovery in IT field. These are
Preventive measures, detective measures and corrective measures. As “Prevention
is better than cure”, the first measure is concerned with the prevention of a
disaster. Disaster Recovery categorizes into two main categories, natural
calamities and man-made disasters. Natural calamities like flood, earthquakes
and tsunamis are uncertain and cannot be merely prevented whereas man-made
disasters like theft or attacks like 9/11 attack can be avoided by adopting
prevention techniques beforehand. Setting up a business in
natural-calamity-free place is the best possible way to avoid disaster from
hurricanes or landslides whereas installing high security and fire
extinguishers in office can be the measure to prevent theft or fire. If the
preventive measure cannot be taken, detective measures are taken which is
concerned with the detection of arriving disasters. The last measure,
corrective measure, aims at retrieving the data stored in the system.
Disaster
recovery has various strategies and every business firm that opts for the DR
need to bear certain factors in mind before selecting the most suitable one.
Basically, selection of Disaster
Recovery Strategy (DRS) depends upon Recovery Time Objective (RTO),
Recovery Point Objective (RPO) and budget of the firm. The maximum period of
tolerance after which data of a business enterprise may get lost in an incident
is known as RPO whereas RTO is the duration of time within which the firm that
has suffered a disaster can be restored. Every firm varies in size and so does
its data. Hence, budget for Disaster Recovery varies according to its RPO and
RTO. Basically, selection of DRS is based upon cost-benefit analysis that is
usually done by experts.
Business
enterprises have received appreciable assistance for Disaster Recovery. The
survey states that 43% of corporations that face a disaster in which firm’s
data get lost never reopen whereas 29% of commercial organizations dissolve
within 3 years after suffering the disaster. In such market, Disaster Recovery
provides a helping hand to enterprises by restoring the firm’s data position to
its last stored recovery-backup.
