Disaster recovery refers to a group of strategies, tools and processes to allow the continued recovery or restoration of critical technology infrastructures and networks after a major natural or man-made disaster. The concept is based on the premise that all information in a computer system cannot be lost forever. It also assumes that computers and their related components will continue to be functional for some time despite of any physical damage, failure or interruption. These ideas are generally considered to be part of the IT service support as well as maintenance provided by most companies. Therefore, disaster recovery becomes one of the key factors to IT operations.

There is a growing trend among companies to put in place a disaster recovery plan. They feel that it is a necessary investment to secure their long-term viability and maintain their IT infrastructure resilience. Most companies are ready to spend money and resources to implement disaster recovery. This however does not mean that disaster recovery is an easy task.
Disaster recovery takes a number of steps and involves a number of elements. Each of these steps builds on the previous one and integrates them in a way that allows redundant backups to be made. If you are working with a small business, you may be tempted to put off setting up a backup disaster recovery plan and consider it a waste of time and money. However, taking this attitude when you face a disaster can be a mistake. As a matter of fact, it could prove to be the best disaster recovery plan that you have ever developed for your business.
One of the primary aspects of backup is to make sure that your servers and networks function properly and are available at all times. In terms of server backup, there are two methods - automated backups and manual backups. Automated backups perform regular backup of the databases, files and applications in the database servers. These are generally done once per day. On the other hand, manual backups include placing duplicate copies of important data on another server or place it in different locations to protect against loss of the data.
While both backup methods work effectively, there is still a difference between them. While an automated backup puts all of your information into a single place and performs the backup automatically, it does not guarantee that all your information is kept safe. In addition, the process can only recover important data. It is very difficult to recover the rest of the data from a backup server that has been compromised. There is also no guarantee that the backup contains the entire range of data which may be critical for some users.
Disaster recovery is all about protection and keeping backups for critical information. It ensures that all systems and applications are operational in the event of system failure. It also includes other functions such as restoring networks and data in the case of some physical damages. There are a number of benefits associated with disaster recovery and these are the reason why it is important to choose the right service provider for this service. The key benefits are better scalability, lower costs, enhanced flexibility and improved control.
Scalability is basically about the ability to accommodate growth in terms of both traffic and storage. This implies that you can make changes to your backup procedures at any time and you can easily integrate them into your business' current practices, without having to break the continuity of your business. In fact, in the event of system failure, your backup procedures will simply back up the information contained in your NVRAM files.
In addition to this, backup disaster recovery provides easy access to your files even in the event of system failure. You do not need to take a hard drive and have it installed on a server just to have full access to your files. This allows you to access the files easily even if you are not in front of your computer. When it comes to control, you have greater control over the process of backup recovery procedures. This means that you can choose how often you want to have full access to your files or you can choose to have the NVRAM backups made automatically at regular intervals.
