What is Data Deduplication?

As data volume grows within organizations, IT managers are tasked with making decisions on how to manage anddata deduplication protect their data. In the past, IT staff have been required to purchase more storage or eliminate unnecessary data. Today, they can rely on data deduplication technology to solve the problems of data growth. So why is data deduplication so important? A main reason is because it has the ability to change data management and data protection solutions by reducing the cost of storing and transferring data.

What is Data Deduplication?

Data deduplication, sometimes called “intelligent compression” or “single-instance storage” is a technique for eliminating duplicate copies of repeating data. Data deduplication is an automated process and this is used to improve storage capacity. In backup, it can occur before data is transferred to the backup sever. We’ll learn more about how Asigra implements data deduplication a little bit later.

What are the benefits?

Increased network bandwidth – no copies are needed to be transmitted over the network if deduplication takes place at the source

Faster recoveries – ensures that line-of-business processes continue without interruption

Compliance – you’re able to still have the ability to respond to legal and corporate data storage compliance requirements without storage overload.

Fast return on investment – because you’re buying and maintaining less storage.

What are the benefits of using Asigra Cloud Backup™ Integrated Data Deduplication?

Asigra Cloud Backup identifies duplicate data by looking for the same data queued for backup more than once. All data is compared based on its content, so it does not matter if the files are on different servers or have different names. Initial backup is a full backup. From that point on Asigra Cloud Backup only transmits new/changed data (incremental forever). This results in significant bandwidth savings.

Data compression – the compression ratio achieved with data compression is dependent on data type. Higher compression ratios can be achieved for databases than for image or audio files. Since, compressing already compressed data can increase the file size, Asigra technology has the intelligence to detect compressed files and it skips the re-compression of such files.
