Disaster recovery services – important for all businesses

Posted by admin on December 23rd, 2008 at 04:08pm

These days everyone understands the importance of data backup. The loss of important data can be completely devastating for a company, or even individuals. Using an online data backup service and disaster recovery solution is important for ensuring the safety of your data.

Using an online data backup service ensures that you will not lose any data in case of a technical failure in your company’s servers or computers as the data is stored online without using CDs/DVDs. This is an easy way to create a data backup, which can be used 24hours.

Disaster recovery solutions are a must, as accidents happen suddenly. When a fire breaks out you can do nothing to save the data bank. But if you have a disaster recovery plan in place, your business can be up and running in a few minutes even in case of a disaster.

Disaster recovery solution facilitates the use of remote standby servers to take over an application in case of server or application failure. The stored data is replicated in real-time to the remote site using data replication software or storage devices. When the system detects a failure, the recovery procedures are immediately started.

Presently there are two methods available for disaster recovery:

• 2 node disaster recovery: one server is on the local site and the other one at the recovery site.
• 3 node disaster recovery: Two servers at the local site and another at the recovery site.

The 3 node disaster recovery mechanism is preferable as it permits easier recovery for non-disaster related failures and high reliability against WAN failure.
