Data duplication is the biggest bugbear of backing up to disc. Chivas Brothers, the Scotch Whisky company, has deployed CommVault to manage data deduplication.

Chivas Brothers stores approximately 90 Tbytes of data, growing 15% per year, which has meant tape back-up is no longer feasible. "The challenge for back-up is that tape is not fast enough," said Les Gilfillan, network manager for Chivas Brothers. "We realised we had to move from tape to disc and realised we would need deduplication."
Chivas runs JD Edwards One and Oracle database. By using CommVault Chivas Brothers says its operations have improved, due to increased reliability of mission-critical back-ups and restores. In addition, expedited Oracle back-ups and granular Microsoft Exchange restores maximise the availability of mission-critical data.
Storing duplicate data on a back-up disc is an unnecessary expense. At Chivas, CommVault is part of the back-up process. The Simpana software built into CommVault deduplicates data from the company's HP EVA disk storage system. It allows Chivas to reduce up to 90% of protected data, which means it can retain up to three months of data on disc.
In essence, deduplication monitors what data has changed. "If a file has not changed it does not get backed up," Gilfillan said.
The deduplication also helps Chivas back up across its wide area network. The company operates 30 sites with file and print servers. All sites are backed up remotely using CommVault's enterprise data replication system.
