These applications can provide options for specific types of backups (such as those for Exchange Server and SQL Server) as well as disaster recovery options, networking functionality, centralized management, and support for more advanced hardware.Once your network is set up and running properly, your users will get the most functionality out of the network.Try taking a network offline for even 10 minutes, and your users will scream and complain.
If your company loses their data, can they survive Probably not. Most companies would go bankrupt if they lost all of their data and had no way to recover it.

Active Directory is the heart and soul of a Microsoft network, and losing your data would be a catastrophic event. Makecert Windows Server 2012 R2 How To Protect ActiveSo, lets start by discussing how to protect Active Directory. From network authentications to file access to print and web services, Active Directory has become a mission-critical component of your business. Therefore, the importance of backing up the Active Directory data store should be evident. The same goes for Active Directory itselfit too should be backed up by being saved. This way, if a massive disaster occurs in which you need to restore your directory services, you will have that option available to you. Mean Time Between Failures (MTBF) is the average time a device will function before it actually fails. There is also a rating derived from benchmark testing of hard disk devices that tells you when you may be at risk for an unavoidable disaster. Some types of failures, such as corrupted hard disk drives, can result in significant data loss. For example, suppose a system administrator accidentally deletes all of the objects within a specific OU. Clearly, its important to be able to retrieve this information from a backup. Or a file is accidentally deleted, and a user does not discover that fact until much later. By keeping multiple backups over time, you can recover information from prior backups when necessary. In such cases, the loss of data might require valid backups from which to restore critical information. It allows for basic backup functionality, such as scheduling backup jobs and selecting which files to back up. Figure 3.1 shows the main screen of the Windows Server 2012 R2 Backup utility. Factors include what to back up, how often to back up, and when the backups should be performed.
