Intellectual resources are precious in that they are the culmination of human endeavor. History is witness to the fact that priceless treasures have been lost to the ravages of time and tyrants, to piracy and persecution because there were not enough of them. Prior to Gutenberg and the invention of moving type, each manuscript had to be handwritten, making books tremendously difficult and time consuming to make, and costly to possess. Printing is a boon to mankind as it enabled reproduction of multiple copies more easily. Similarly, the computer revolution has generated a lot of data, software, and other intellectual resources which are the products of hundreds of man hours of toil, and are irreplaceable. To prevent any accidental or deliberate damage to the resources, backup is a widely used practice. A timely backup of useful and essential resources will enable one to restart services in the event of a catastrophic loss of original data.
Backup is the process of duplication or replication of data so as to ensure its survival in case of natural or man-made calamities, accident or theft and robbery. The logic is that, it is more difficult to destroy multiple copies than it is to destroy one. If the backups are situated in a different physical locations, if they are stored in different media, and if, in case of theft or robbery, the presence of backup is not known, then the damage from data loss become minimal. Backup can also refer to the services provided by some companies to get the backup of client companies done, or to the software and technologies used to enable this process. Thus, there are various softwares available to get the backup done. Backup may be done by an in-house team, or a service provider; it may be taken daily, or many times a day, or it may be taken at some other interval; backup may be kept with the original, or at a different place; backup may be taken on a similar media as the original, or otherwise, etc. Usually, backup is taken on CDs and DVDs, and at times on hard-disk based systems. Many higher capacity disks are coming into the market soon, and one may be sure that they would be used for backups in future.
