How is Backup Different From Disaster Recovery?
Do you think hosting server backup and disaster
recovery is the same thing? Dont worry, youre
not alone who thinks they are similar. These two
terminologies hold diverse importance and are not
tradable, but rather share a calm couple of
likenesses. Disaster recovery is a vast concept,
whereas backup is an element of the massive DR
abstract, both services are offered by data
center service providers. Many organizations
often regard it in the same context and end up
tangled in a huge coil of trouble in the event of
a disaster. Difference Between Backup and
Disaster Recovery 1. Frequent file
backups Server Backup processes are performed in
different modes daily, weekly or monthly. Users
can choose to backup file based on their
requirement, but typically companies opt for
daily back in order to ascertain data retention
(constant storage of business data) at a single
location. On contrast, disaster recovery
strategy requires to scale out the Recovery Time
Objective (RTO) that states how long the business
can survive without IT equipment post-disaster.
Lower the RTO quicker will be the business
continuity.

2. Recovery ability Backup is beneficial for
immediate access, which means if you lose all
your data in a disaster, you can quickly restore
it and get your business going. Disaster recovery
solutions reestablish your complete
infrastructure by giving a substitute domain,
outfitted with the necessary equipment and
systems, where you can process the IT operations,
in this manner maintaining a strategic distance
from business disruption for prolonged
period. 3. Outlining strategies Its not rocket
science to prepare a backup plan. It is quick and
easy and you require to look at two main feature,
Recovery Point Objective (RPO) and data
retention. However, designing Disaster Recovery
plan is complex that needs the CIO to consider
numerous things to build the ideal strategy. For
instance, analyzing mission-critical
applications, determining what data needs to be
backed up, developing recovery order, Disaster
Recovery plan testing and so on.4. Mode of data
recovery When any company does backup or disaster
recovery, it needs to determine the right mode of
operation for business continuity. It needs to
determine processes that will lower downtime. It
also needs to chalk out a plan on data revival in
the case of a hardware failure. For example, if
your server malfunctioned, you wont be able to
quickly get back to normal work if you only had a
file-level backup. In order for you to return to
normalcy, your hosting server would need to be
replaced with software, data re-installed the
whole system configured to its required settings
and preferences. This process could take a long
time could only reach success if you have all
your software licenses ready with a clean copy of
your data. Thus, disaster recovery could take
time backups could also turn to be a complete
failure.

5. Planning Process The planning process also
proves itself as a major difference between
backups disaster recovery. Planning a backup
daily or routinely is easy as it will only
involve fulfilling RPO ( recovery point
objective) and data retention requirements. The
Business Continuity Disaster recovery plan, on
the other hand, will require proper planning. It
will require determining systems as critical to
backup while creating a recovery order and
communication process. 6. Additional Resource
requirements Backup simply involves backing up a
copy of data to its intended original source.
Disaster recovery strategy requires a specific
environment where the data can be stored safely
restored. This specific environment generally
includes physical resources, software,
connectivity, security etc. 7. Benefits The
overall aim of a Disaster Recovery plan is to
mitigate risk and downtime. It also needs to
focus on maintaining compatibility and to prevent
outages. Backups, on the other hand, serves a
much simpler purpose of only restoring the data
to its original source. Ultimately, both the
approaches are essential to protect your data and
applications. But make sure you understand the
terms before you just take the plunge. Backup can
protect your business from minor accidents, but
Disaster Recovery Plan is capable of saving you
from the sinking ship. Thus, backup is a copy of
your mission-critical data and applications,
while Disaster Recovery as a Service ensures the
safety of your entire infrastructure.
