Backup solutions can be very confusing. The most important thing and also the most frequent thing about backups is that they are not usually the thing that the person using them expects them to be. For instance, if a person backs up his hard drive and then later tries to restore it, he comes to a conclusion that only the files can be restored and that the operating system and the programs that had been installed cannot be restored. This can turn out to be a devastating problem is some of the programs that have been lost are critical to the purposes of the user.
There are several such examples that can be listed to illustrate the failure of file based backup systems for taking backups of crucial and important data. These problems are numerous and have cost organizations millions and this is one of the reasons why he need was felt for a new backup system that would truly live up to its name A Backup System. The search was on for a system that could literally restore the entire state of the system to a previous backed up position. Everything, including the installed programs and the operating system would be restored. This is of critical importance for all the corporations that value data security.
This type of system called the disk imaging system literally creates an image, an exact image, of the entire disk and when it is asked to restore the backup, it readily restores the entire image that had been stored as a backup. This is what ensures that all the files remain the same and do not change and there is absolutely no change to the file structure of the disk, thereby ensuring that the restored backup is a literal clone of the disk and there are no noticeable differences.
