Deduplication Backup Software Info

Apr.30, 2010 in Computers

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. 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. An explanation of these points follows which you should find useful to educate yourself in order to select the deduplication backup software that will best suit your requirements.

Computers or computer networks often contain several copies of the same file but single instance deduplication ignores the duplicates and will just backup one instance of a 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. As an additional benefit, deduplication technology also eliminated redundancy with regards to multiple backups of your operating system. 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. The technology can also be integrated directly into your backup software. 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. In addition, software does not require that any serious changes be made to your computer 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.
