Disaster Recovery as a service

Disasters are always painful. Yet they are inevitable. Is anyone protected against them?

These are difficult statements and questions, yet there are many ways to cater IT related services so there would be no or minimal impact during disaster. We can refer to ISO 27001 and ISO 20000 to ensure the IT will have the necessary plans to recover from it or to mitigate the risks.

First and foremost, one has to define what is called “Disaster” for companies. Usually when more than 40% of the business is affected, the managing director would call it Disaster. It might not be even related to ICT, but the above is a general statement. There is always a discussion about the true figure, and it varies between 30% to 80%. Below that level, it would be called incident or problem.

Let’s now focus on disasters where ICT has a role. Business has been relying on an ERP or Web shop and they are not available during the business hours. Or services such as Taxi Management and ordering systems would go down for a while.

Having a reinforced and tested recovery plan, is thus very important for any business owner. It is compared to an insurance that one buys at the beginning of the year, or the 2nd engine of the airplane that works yet may not be necessary.

Near line Disaster Recovery

This type of disaster recovery has been used for many years in banks and telecom operators. It is costly and is based on high capex / opex policy and procedure. However, it has shown to be a robust process.

Clients must rent a certain capacity from Cloud Acropolis and have them on at all time. The client’s administrator must setup the servers in a proper manner and setup replication at OS or binary level of the application in one hand and Databased synchronization via ASYNCH in the other hand. Basically all the needed files and DB logs need to be sent to the VMs in Cloud acropolis every 5 to 10 minutes. It is important to check that all the changes are implemented at each transfer. The normal periodicity of this transfer is every 15 minutes.

In time of Disaster, the Client’s IT administrator must update its network settings so the users can be directed to cloud acropolis IP addresses
