INTRODUCTION

Disaster Recovery for large datacenter is indispensable for any enterprise that has been operating mainly based on Information Technology. Depending on the extent and impact of Information Technology on enterprise activities they will be have safety correlative solution.

Protecting the enterprise’s data system is always very important and also the role of data centers so as the information and data always in the ready access. Besides the use of data backup in place we should prepare backup data center for the main data center in case of incidents as natural disaster, fires,…etc

Nowadays, IT has influenced to most of the enterprise / large organization, therefore, to stop the system will cause damage to the financial business as well as its credibility, so that we should build the solution for  the whole system is not affected whenmajor incidents such as earthquakes, natural disasters, fire ... is very needed and professional disaster prevention solutions are supplied on purposeto help businesses always preserve alltheir activities in conditions most severe natural disasters by our company.

TECHNOLOGY SOLUTION 

Depending on the importance of data as well as each company,we always have suitable backup solution as follows:

Simple solution, back up data only

With this solution just has the backup plan to tape or other devices. Data is backed up daily and tapes are moved to offsite for storage, therefore when we need to restore the tape is brought back to restore the crash data.

With this solution we only backup data combine with backup center, but only safety data. When incident is happened at the centre we had to ensure the data safely for the enterprise but need time to recover the operating system. However, the data had just backed up in periodically so that may be a small loss of transaction data in range between backup periodically. Advantages of the solution are low cost and almost ensure no  data loss when happened disaster   

With this solution we need:

• Building a backup data center with compatible devices.
• Data is backed up daily and tapes are moved to offsite for storage.
• When the main data center incidents: the tape was taken to the offsite data center backup to restore data.

With this solution, we ensure no data loss and to overcome the above disadvantage of the solution through backup data continuous and automatic transmission line but highly investment cost. This solution is not ensure safety for all backup data online but the system needs a short time to do, but this solution can ensure almost 99,9% data backup safely.

To implement this solution we need the following elements:

• Need to build the backup data center with compatible devices.
• Backup data online to backup center with high-speed links.
• When the main data center breakdown, backup data center recover the available data and ready to replace the main data center

Building back up data center solution and comprehensive with high-speed transmission

With this solution we ensure the entire enterprise data center is back updata comprehensive capabilities continuously.That any transactions made any changes in the main centers are immediatelycomprehensive on the backup center Although this solutionensures business datais always conserved in any case of any problems in the main centers, but outside the high cost disadvantages, then the solution is limitedbecause it takes a while certain short timeto recover when the problem occurred.

To implement this solution should:

• Requires construction of back up data centerwith compatible devices.
• The data is comprehensive between the two sites withhigh-speed links.
• When the main data center crash, back up data centers are ready to replace the main data center. 

Total DR Solution

Depending on customer requirements, we make sure offers customers total DR solution in terms of data as well as automatic recovery operations without interrupted the system in any case.

In this technical solution we build a reserve for almost of the components that affect the business activities of the DR international standard. That includes: data, server, network, security system.... as the reference model below
