Company data is the lifeline of any business, customer account details, invoices, supplier information, staff information to mention a few are all key to the continuation of a business. Imagine if for whatever reason the server that holds that information fails, what would your business do? How long would it take for your business to recover from a disaster? More importantly what would the loss of income be for that period and moving forward?
The last few years have seen an increase in the use of virtualised servers. Virtualisation is used with a larger physical server that is running with a number of smaller virtualised servers usually with a specific purpose. An example would be a virtual server for SQL, one for Exchange email, another for applications. Although there are countless merits of having a virtualised environment, a major issue with this type of infrastructure is a failure on the main host server which means all hosted virtualised servers will also fail which in turn increases the importance of virtual machine backup and restore plan.
