Businesses have come to rely more and more on software applications and electronically stored data in the running of the business. There is a wide range of IT management software available to maintain data integrity, as well as modern resources for minimizing downtime.
One area that IT managers are now increasingly interested in is virtual backup of data and applications. This type of backup has been something of a spin-off from the growing use of virtual applications.
Virtual applications are growing in popularity. Virtual applications exploit the use of cloud computing. Companies that use cloud computing can save significantly on software, hardware and labor costs.
A virtual application is one that resides on a virtual machine or machines in the cloud, and is often hosted on third party infrastructure. Instead of a company buying licenses for a particular word processor, and then installing that word processor on its servers and client machines, it can sign up to use the same word processor hosted in a cloud computing arrangement.
This removes from the company the responsibility for installing, upgrading and maintaining the application, since all that work now falls on the cloud computing provider. The company saves on the cost of the application and does not need in-house support for it.
Another advantage is that the company will only be paying for resources that it actually uses. In the traditional business model, a company has to buy enough licenses for the number of client computers that will use an application. Licenses are often issued in bundles.
This means that a company can end up paying for more licenses than it actually uses now, or will ever use in the future. In contrast, when a company uses virtual applications, it will only have to pay for resources that it actually uses.
Businesses that use cloud computing can also make considerable savings on hardware expenditure. Even a small to medium sized network will need a fairly powerful, and expensive, server at its core. The more powerful the computer, the more expensive it is. A business that uses cloud servers will be able to get by with more modestly equipped machines.
Data backup is an area that has often caused problems for businesses. Very few companies can afford the resources to maintain real time data backup. Instead, backups are often done at regular intervals. If a problem arises that calls for a roll back to the latest backup, several hours of data can be lost.
Even where companies have been diligent in their backup routines, critical data loss has occurred when the backup medium has proved faulty. This can have severe consequences for a company.
Virtual backup is a cost effective way to eliminate these problems. Virtual backups are never dependent on a single medium, and all data is backed up in real time. Data restoration is almost instantaneous, and problems can be resolved very quickly.
