As
per a recent finding, 76% of companies experienced an outage in 2013 and out of
which only 13% of outages were a result of natural disasters, majority of
outages resulted due to human error and power malfunction. In any case, we expect
disaster recovery to be fast, however, a data backup can surely ease the
process to some extent but are not the solution for disaster recovery as it
cannot provide any application recovery solutions.
Most
common methods used for back up are an offsite backup or cloud storage. These
data backup methods are convenient and cheap but are not sufficient when a
disaster strikes. Data backup can only ensure that data is stored and can be
accessed but will take a lot of effort
to compile together scattered information, spinning up new servers, piece
together data and applications to ensure operations can continue.
On
the other hand, disaster recovery services can speed up RTO (Recovery Time
Objective) from days to hours or in some cases to minutes. In this case,
organizations comes back in form instantly wherein systems, processes and data
becomes quickly accessible whether it be accessed via remote on your mobile
devices or is available at other physical locations.
The
most preferred option for Disaster Recovery and Data Backup is Onsite Backup, Offsite Backup, Co location and Virtual
machines. In an onsite backup, some kind of physical storage option is utilized
which provides a realistic disaster recovery procedure wherein imaging of
servers is done and data is stored locally so that it can be accessed quickly
in case of a disruption, including lost documents, server hardware failure.
Another option is an offsite backup, wherein a company moves its critical
applications and data in a different physical location. In this process,
weekly, monthly or daily backups are done.
