Disaster recovery (DR) is the process, policies and procedures that are related to preparing for recovery or continuation of technology infrastructure which are vital to an organization after a Natural or Human-induced disaster
A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods, volcanic eruptions, earthquakes, tsunamis, and other geologic processes.
an element of human intent, negligence, or error; or involving a failure of a human-made system. It results in huge loss of life and property. It further affects a person's mental, physical and social well-being. e.g. Crime, Hacking, Arson, Civil disorder, Terrorism, War, unfix of plug…
If company host their web by themselves, any disaster occur, such as flooding, fire and etc. Servers kept in the office maybe damaged or out of control. The web will down The business will stop until the server has fixed The data store inside may lost The reputation will lost from clients
Disaster recovery is a subset of business continuity While business continuity involves planning for keeping all aspects of a business functioning in the midst of disruptive events, disaster recovery focuses on the IT or technology systems that support business functions.
Users want their systems to be ready to serve them at all times. Availability refers to the ability of the user community to access the system to submit new work, update or alter existing work, collect the results of previous work. If a user cannot access the system, it is said to be unavailable. Generally, the term downtime is used to refer to periods when a system is unavailable.
Maintain the availability of IT assets and data as well as the ongoing business operation with real time replication of data to active and stand-by servers in the data center. When a system goes down Recovery time: within an hour 1 Hour
Backup servers will be prepared for web content and database application High Availability solution captures changes to data and applications in real time and replicate to standby servers, which enables controlled, non-intrusive switching and fast, reliable failover to meet any contingency.
By synchronizing the database to alternative servers in different data center, your critical business information will be safeguarded.
Secure protection of your critical business systems and data with secure transportation of data to offsite location Rapid recovery solution by leveraging WAN for high performance data replication Optimized WAN traffic by replicating only modified content Outages are identified and diagnose root problems for quicker recovery Servers are protected by NCSA Labs certified firewalls and monitored 24×7

Our household broadband penetration rate of 87% and mobile penetration rate of over 223% are among the highest in the world.)
Highly stable, with reliability. two power companies use various fuels for power generation with extra capacity and robustness of supply, as well as emergency support to each other during generator failure. Continues to enjoy a relatively low electricity tariff in comparison with other cities in the Asia Pacific Region. Power supply meets the Uptime Institute Data Centre Site Infrastructure Tier Standard and TIA Telecommunications Infrastructure Standard for Data Centres (TIA-942).
