Your system might fail due to many different causes. The most common ones are:

a. Human error

Human error is one of the most common causes of system failure. For example, a user can accidentally delete or overwrite a critical system or database file. Even though most of the data can be restored from existing backups, some data might still be lost. A great deal of effort will be required to recover from such errors, which will lead to a loss in productivity and high costs to a business. Correctly implemented online backup can dramatically reduce the impact of human errors. This is achieved by continuous backup of all changes to the critical corporate files. If the file is deleted or damaged by a user, it can be easily and quickly restored from the remote server.

b. Hardware failure

Hardware failures can happen to any part of the system, including servers, workstations and storage devices. Eliminating as many single points of failure as possible will protect your business from hardware failures. This is achieved by duplicating most hardware resources which can be utilized in case the primary resources fail. Unfortunately, duplicating hardware resources can be very expensive to implement and manage.

c. Transaction failure

Transaction failure is not a very common type of data failure, but it can have as devastating effect to your valuable data as any other type. Transaction failures occur when something happens to your server during an update of a transaction such as data loading to the database. The database could be left in an inconsistent and unusable state, and will need to be repaired before users can use it again.

d. Disaster

Natural disasters and malicious human activities would completely disrupt your day-to-day operations. These include fires, floods, theft, earthquakes, etc. Remote storage of critical business data is a necessity to protect your company from these unforeseen events.
