If you have put in place disaster recovery (DR) processes, but have not made any effort to test its efficiency, you are doomed. If that sounds like a doomsayer’s prediction to you, you will be damned. Harsh as this seems, it is the truth. The strength of your IT will be in direct proportion to the amount of time and money you invest in disaster recovery. You need to test, test and constantly test the efficiency, efficacy, and reliability of your disaster recovery processes. If your data resides in a public, private or hybrid Cloud, the need becomes all the more urgent.
DR begins with the initiation of backup of the data you want to recover. Has the data been backed up as per schedule? If you have opted for continuous backup—is it being backed up continuously? Has it been correctly backed up? Make sure the encryption, de-duplication, and compression technologies have not corrupted the information. Do you have the encryption key? Is the decryption happening as promised?
Once you are sure your data has been backed up correctly, and is being backed up correctly as planned, you need to monitor the backup. A number of tools are provided by Cloud services to check whether the data stored in the repositories are complete and error free. However, a complete DR test should be scheduled as frequently as required. The frequency will be determined by the volume of data that is generated on a daily, weekly or monthly basis. If the volume of data generated is very large, a weekly test may be ideal.
The nature of the DR test will be determined by the level at which the enterprise wants the test. Some organizations want the test performed at the production level or the application level. Each type of test will be unique.
Cloud backup and recovery DR testing is often described as work in progress. With Cloud backup services making DR testing simpler, more and more organizations are performing regular DR tests using Cloud service vendor tools. As a result, companies are better prepared for disaster and more agile in their recovery. Time to recover (TOR) has drastically reduced and organizations can now afford to set lower Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs) with impunity.
Disaster recovery is no longer regarded as an expensive insurance policy that may or may not be used. It is part of the package. It comes free with Cloud computing!
