Enterprises adopt DR as SMEs stay away
Disaster Recovery is an area that is now
noticed by CEOs too. As large enterprises, banks and oil companies
have decided to go in for DR solutions, the potential for DR implementation
has increased immensely in India. The market for DR is expected
to increase substantially in the coming years, says ABHINAV SINGH

Once upon a time, Disaster Recovery (DR)
in India used to mean a tape backup stored at a different location.
Today, a DR implementation has become a part of the policy of many
large scale organisations that just cannot afford to do without
a DR plan. Realising its importance, the top management in some
Indian companies are constantly stressing on the need to allocate
a separate budget for DR implementation.
Yet, compared to the West,
the domestic market is still nascent and has to go a long way to
reach the levels of its western counterparts. The demand for Disaster
Recovery Services and Solutions in the Asia-Pacific region has seen
consistent growth of approximately 20 percent per year, over the
last two years. According to IDC, China and India will be the fastest-growing
markets for DR services in the Asia-Pacific region (excluding Japan),
with a CAGR of 46 percent and 36 percent respectively, during the
next five years.
What
is driving DR in India?
Factors driving DR’s popularity among Indian users include increasing
threats in the business environment (terrorist strikes, war, earthquakes)
and the 24x7 nature of today’s business operations. V Vivekanand,
Hitachi Data Systems’ business development manager says, "Companies
in India are embarking on DR initiatives to gain an edge over competitors.
More and more Indian firms are now operating in a 24x7 environment,
especially large enterprises, where global operations are the norm.
E-commerce also requires organisations to implement a DR strategy."
For banks, the complexity of
huge amount of data they generate is spurring them on. Large banks
like ICICI, HDFC Global Trust have millions of customers spread
across the country who carry out daily transactions. The large number
of transactions translate to massive volumes of data. To maintain
customer confidence, banks have to maintain the sensitive, complex
data, which has to be at the disposal of its customers at all times.
Oil and natural gas companies
like BPCL and ONGC have gone in for large DR implementations too.
ONGC, which is into oil exploration, generates huge amounts of seismic
and exploratory data. Hence, it becomes necessary to maintain the
integrity and the criticality of the data for future explorations.
BPCL’s DR implementation was undertaken by HP. Avijit Basu, HP India’s
marketing manager for Network Storage Solutions says, "BPCL
has more than 4,500 petrol dealers and more than 1,000 kerosene
dealers across the country. The company has to maintain a continuous
link in order to maintain its credibility and integrity. It went
in for storage consolidation and later implemented a DR site."
Similarly, for the manufacturing
segment running ERP, CRM and supply chain solutions, DR is helpful
in maintaining the criticality and integrity of the system. For
such companies, losing data due to any unforeseen eventuality can
mean a huge loss to their business.
In India, recent times have
shown that an increase in the level of competition and market demands,
together with increased dependence on technology for core business
processes have necessitated the need for DR by companies.
Recent years have also seen
a tremendous growth in the software and the ITES sector in India,
which are also going in for DR services in a big way. Says Rana
Dutta, APACregional director at Movinture Storage Networks, "A
disaster could mean a huge loss of manhours, specially for the ITES
sector, and hence it is of utmost importance for this sector to
go in for DR. For the ITES sector the whole revenue model is built
around the volume of calls they receive and make. They have to be
in constant touch with their customers round-the- clock. A slight
break in communication lines can prove detrimental to their businesses;
hence they are going in for DR. "For instance, GE’s call centre
division in India has gone in for DR in a big way. Anal K Jain,
Network Appliance’s managing director for India & SAARC says,
"We have implemented five DR sites for GE’s BPO division. The
sites are spread across five Indian cities. All these DR sites are
linked and act as a backup for each other in case of a disaster."
DR
planning by Indian companies
Due to the increasing popularity of DR in India, many Indian companies
are going in for DR planning before the actual DR implementation.
Ashish Kumar, country services executive for India at IBM Global
Services says, "We offer services to help companies assess
the impact a disruption could have on their critical business processes.
As the technology environment has changed to accommodate the e-business
marketplace, companies are assessing the associated risks and quantifying
the financial and intangible impact on their business. Our consultants
provide business impact and risk management analysis services to
help determine an organisation’s most critical processes, vital
assets and gravest threats."
Similarly, Dutta remarks, "The
planning process in business recovery planning in case of a disaster
attempts to identify all the possible adverse incidents and develop
a series of specific actions to be taken before an incident occurs
to facilitate the resumption of business activities following the
incident."
Targeted
verticals
The banking and financial sector has been one of the strongest verticals
opting for DR in a big way and is expected to grow by leaps and
bounds in the near future. Citibank, ICICI Bank, HDFC Bank and the
National Stock Exchange have all adopted DR. Besides, DR has assumed
immense significance amongst the oil and petroleum sectors. Many
telecom companies, data
centres, software development centres in India have also had DR
implementations. The manufacturing, health, travel, and hospitality
sectors in India are also gradually implementing these solutions.

in India |
What
the future holds?
Although Indian users have shown keen interest in adopting DR, much
needs to be achieved in terms of attaining parity with western markets.
Says Raghu Prasad, Exabyte’s business development manager, "The
Indian market is growing and the customers have realised the importance
of DR, but the adaptability of new techniques among Indian users
has been a bit slow. That needs to shoot up if the Indian market
wants to compete with the West in terms of DR implementations."
Apara’s managing director M
S Sidhu says, "Data generation by Indian companies is low when
compared to that in western countries. DR implementations have therefore
been on a smaller scale. Moreover, due to the limited bandwidth
at high rates, few companies are going in for DR on a large scale."
High infrastructure costs and expensive bandwidth, which are both
prerequisites to have an efficient and effective DR, are one of
the primary reasons behind the slow adoption of DR in India.
Despite the fact that latest
DR techniques are now available in the Indian market, it is estimated
that a majority of Indian customers are still relying on tape backup
for DR. While SMEs cannot afford the huge investments that DR entails,
large enterprises have shown keen interest in DR. EMC’s country
manager T Srinivasan says, "For each DR implementation the
cost varies as it depends on the requirement of each company. Most
of them start with storage consolidation before going in for DR
implementations." But it is expected that in the coming years
bandwidth rates and infrastructure costs will come down in India
which will give a further boost to the domestic DR market.
- Backup to tape:
Some users do a full backup on a weekly or monthly basis
by taping and shipping the tapes to a remote DR location
or storing them in a fire-proof/earthquake-proof safe vault.
- Replicate data from servers:
Data is replicated from servers in the data centre to servers
in the remote location. Servers that need to be replicated
need several layers of software like volume managers, file
systems that have capabilities to separate changed blocks
(not files), and replication software that can ultimately
transfer changed blocks.
- Replicate data from storage
to storage: The method involves one storage system
talking directly to another in the remote location and replicating
data. The DR site can have a fixed set of servers that can
start accessing data / delivering services when a disaster
occurs. Another possibility is that tape backups can be
done at the DR location, and the tapes are sent to a third
location or vaulted to offer another level of redundancy.
