DATA DEDUPLICATION BACKUP AND BACKUP COMPRESSION Data deduplication backup works similarly with compression when it comes to function - to minimize cost on storage. But in an information system, decision in choosing a particular storage technique that can save money and still offer quality backup is essential. To help you come up with the best decision on your storage system purchase, consider these comparisons between data deduplication and compression.
Compression is changing the size of a data into other forms that will occupy lesser storage space. Duplicated parts are being deleted to do this. 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.
Compression of database and backup can also be done on SQL servers in order to save storage space. To allow compression on database, the tables and indexes contained therein are being compressed. When tables and indexes are created, they can already be compressed. However, compression is more meticulous for SELECT, INSERT, AND UPDATE. It is also more costly compared to decompression. As such, Microsoft does not really encourage compressing tables and indexes smaller than the whole database or in case tables are used for DML functions.
In SQL servers, backup compression is off by default. The sp_configure should be manipulated and set for the compression to function. This leads to a faster backup and retrieval procedure.
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 used is also decreased by almost 90%. Any change of any file in the network is provided backup unless there is a duplicate delivering up to 10 times faster the backup.
Dedupe systems these days performs both data deduplication and compression. Storage space savings is largely increased with this process.
Compression and data deduplication both function as saving in storage space and bandwidth. Both can improve the backup quality and the performance speed as well. Make an informed decision when choosing the compression or data deduplication system to employ.
