Deduplication Backup Software

Feb.09, 2010 in Computers

If you are interested in Deduplication Backup Software as a backup solution for your office data then there are three things that you need to know. The three things are, what are the implementation options for this kind of data backup solution, what are the costs and how does the technology work. 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. This results in a situation where redundancy is greatly reduced and you therefore save a great deal of space on your storage drives. 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. Your first choice is to employ a server that is dedicated to data backups with the deduplication software installed 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. The disadvantage of software however is that it can disrupt productivity when it is being installed and its maintenance can often be quite complicated. It is wise to also understand what the pricing is for deduplication disk systems.

The cost of a deduplication disk system is usually similar to the pricing for a type library of the same size. Pricing averages at about one dollar for every GB backed up. Since the price is about the same as tape libraries customers do not loose anything plus they gain all the benefits of discs including the fact that they save a lot of storage space using disks over using tapes. 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. Figuring out what the costs are is the only way to budget for this vital backup plan. Put these concepts to use and you will easily find the deduplication backup software that best suits your needs.
