We think that there is no real benefit for the Commvault to deduplicate Transaction Log data. Maybe some compression benefit, but today we deduplicate practically everything. I started another topic (Difference between Incremental Storage Policy and Log Storage policy) to ask about the differences between Log Storage Policy and Incremental Storage Policy. The idea is to have a specific Storage Policy for Database Agents Transactional Logs with deduplication disabled. By examining some backups jobs, we noticed that Savings Percentage comes entirely from Compression. Due to its nature, It seems that there is no gain when deduplicating variable data like Transactional Logs.
By disabling deduplication for those data, in theory, we can keep DDB smaller and reduce Q&I times. Am I right?
