DATA DEDUPLICATION BACKUP AND BACKUP COMPRESSION
Data deduplication backup and compression offer similar purpose in a backup program-to save storage space. However, while a sound information system requires saving in terms of financial aspect, the quality of the backup should never be compromised. The following are key points to consider to guide you on your decision.
Compression is changing the size of a data into other forms that will occupy lesser storage space. Identical portions are removed in order to make this possible. Technologies for data compression include Winzip, Compress, and Unix. In the hardware side, tape drive compression can be done to compress its data improving tape drive speed.
For the purpose of storage saving, SQL servers can also perform compression on its database and backup. Specifically, tables and indexes are the ones being compressed in data compression. Once the tables and indexes are created, this can already be done. Nonetheless, compression requires more time and effort. It is also more costly compared to decompression. For this reason, when tables are used for DML and they (together with the indexes) are smaller than the data base, Compression is no longer advised.
For SQL servers, backup compression still needs to be activated. The sp_configure should be manipulated and set for the compression to function. Because sizes are smaller, this results to a faster backup process as well as recovery procedure.
Over time, data deduplication backup has been widely used because of its effectiveness when it comes to saving on storage expense. This ensures only a single copy of each data is being maintained on the network. Bandwidth used is also decreased by almost 90%. The system automatically does the backup process every time it detects an alteration on the files.
The best part of these all is that both data deduplcation and compression are now done by many dedupe systems. This makes storage space savings even bigger.
Compression and data deduplication both function as saving in storage space and bandwidth. As a result, they speed up performance and make a reliable backup. Be wise when deciding which data deduplication or compression to use.
