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.
