Hi, Sabar. I couldn't find a TS7569G via Google, but on the TS7650G, also a deduping VTL, after data goes through the factoring (dedup) algorithm it is run through a compression algorithm. You probably won't see much deduplication, but on the first backup you should see a decrease in size similar to the decrease you would see from the compression on a tape drive.
