Data deduplication backup and compression offer similar purpose in a backup program-to save storage space. But in an information system, decision in choosing a particular storage technique that can save money and still offer quality backup is essential. Here are comparative points between data deduplication and compression to help you decide which storage saving technique to avail.
Compression is changing the size of a data into other forms that will occupy lesser storage space. This is basically achieved by removing the redundant parts in files or data. Compress, Unix and Winzip are some technologies that compresses data. In the hardware side, tape drive compression can be done to compress its data improving tape drive speed.

In SQL severs, data and backup compression can be done in its database to save storage space. In data compression, the tables and indexes contained in the database are compressed. This can be done upon creation of tables or index. However, compression is more meticulous for SELECT, INSERT, AND UPDATE. It is also more expensive than decompression. Because of these, Microsoft discourages compression for tables and indexes that are smaller than the entire database or if tables are always used for DML operations.
In SQL servers, backup compression is off by default. Manipulation sp_configure procedure can set compression to work. With this, sizes and backup/restoration time period can be decreased. Data deduplication backup has gained popularity due to amount of saving it can offer in terms of storage cost. This saves only a single copy of files duplicated across the network. Bandwidth is also saved in the process up to 90%. Any changes of any file in the network and is provided backup unless there is a duplicate delivering up to 10 times faster backup.
It is worthy to note that todays dedupe systems do both data deduplication and compression. Storage space savings is largely increased with this process.
Mere compression or data deduplication can both save storage space and bandwidth. It can also enhance backup and transmission speeds. Choose wisely which compression or data deduplication technology to use.
By implementing the right deduplication technology you can significantly lower the costs of the backup systems. Less storage space is needed to store the the files and the time to backup is significantly reduced. It is important to not compress everything since the compression might actually cost more in the long run. By strategically choosing your methods that work for your company you will provide a valuable asset and trim the bottom line.
