The elegance of technology has made our life styles easier than yesterday. It is developing day by day. The best example for its grace is Software. It has eliminated the complexity of different aspects. Everything is happening now in a fraction of seconds! But it has got up with a negative trait as well. If anything goes wrong, sometimes the data which is stored gets formatted instantly. This leads to countless number of problems. Mainly in computers, which are used officially, there exist confidential data which should not be disclosed. If such information gets erased, the company suffers form a lot of problems. To eliminate this burden, Virtual Disaster Recovery has taken birth which allows a back up for the data.
A business disaster occurs when the essential elements of a business are unable to function as normal over a long period of time. Such a disaster can be caused by several things. This includes natural catastrophes, equipment failure or human personnel failure. To deal with a business disaster effectively, you need to have a recovery plan in place.
A good recovery plan has two main facets. First, it aims at preventing such disasters from happening and second it aims at helping you restore everything back to normal after disaster strikes.
Today, organizations completely depend on the virtual machines for storing their critical data as well as applications and need them to always remain available. This is where the virtual disaster recovery comes into the picture. Virtual disaster recovery focuses on taking the backups of the virtual machines instead of the physical servers. VM backup can be taken in three ways – image-based, agent-based and server-less backup. Data replication helps the workloads to move independently between VMs and arrive rapidly after recovery, without the need of manual re-launching of OS and application on a physical server.
The emerging concept of cloud disaster recovery (cloud DR) solution is rapidly gaining acceptance, especially with the small and medium business segments. When disaster strikes your online business from a disaster can be a herculean task which may never restore your business to its previous position. While disasters can hit large and small enterprises alike, disaster preparedness is something that only the large enterprises can invest into. The advent of cloud computing is changing that- there are economic, technical and security benefits for SMBs. Business continuity planning has become cheaper and easier with cloud based disaster recovery solutions. Experts in the field are now talking favourably of a disaster recovery plan in the cloud as there are distinct benefits like cost effectiveness and simplicity of deployment which are not offered by traditional DR solutions.
