By U Learn It | December 19, 2009

People looking into deduplication backup software to backup their office data should familiarize themselves with three different aspects of the software and also the technology behind it. They are how deduplication backup technology works, the choices for implementation of such a backup system and what costs you can expect. What follows is an explanation of these points which will provide you with some background for choosing the right deduplication backup software to meet your needs.

Regardless of how many copies of a file exists on any computer or network, single instance deduplication only saves one copy of the file. Backup software traditionally saved numerous copies of the identical data despite the fact that this created a great deal of redundancy. The technology of single instance deduplication is different in that it identifies all copies of a data file but is only backs up one instance of it and saves the others as pointers. The result of such a system is that you use up much less of the available space in your designated storage location. Additionally, the technology is useful for preventing redundant operating system backups. Implementation of a deduplication system can be carried out in different ways.

There are two different ways to implement data deduplication technology. The first method requires a dedicated server which employs data deduplication software on it. It is also possible to integrate the technology into your backup software directly. The implementation method that relies on software is advantageous since it does not require you to purchase or service specific hardware that will only be used for backing up computer data and nothing else. Another benefit of deduplication software is that there is no requirement for complicated changes to be made on your computer or network. On the other hand, there is a disadvantage to the software in that installing and routine maintenance often disrupts the work flow on your computer or network. It is wise to also understand what the pricing is for deduplication disk systems.

Deduplication disk systems generally cost about the same amount as type libraries that hold similar amounts of data files on them. The average price generally runs at one dollar per GB. This pricing scheme allows consumers to change from a tape system to a disc system which will save them a great deal of storage space and experience the many features that initially attracted them to disks. What you should further keep in mind is that when evaluating the cost of a deduplication system you should consider both your initial output as well as ongoing expenses required to maintain the system.

Understanding deduplication backup technology will help you analyze if it is the right type of backup system for you. Reviewing the different implementation systems will assist you in choosing the specific type of backup you require. Determining the costs will help you budget this system into your company’s expenses. If you have done all of your homework and acquired the right knowledge then it will be easy to choose the right deduplication backup software.
