We're having customers using Exchange, DB2 & SQL backups de-duping just fine. Exchange databases are a total of 2TB per machine, having (if I'm not recalling wrong) 200GB per storage group.
So unless you're talking huge sizes, no, de-dup works fine for databases. And the de-dup ratio is really good on databases tbh.

Just asking. As I recall, the announcements for client-side dedup said it is supported by the API, so therefore should work with TDP's. Has anybody achieved (or attempted?) significant improvements in throughput with backup of large DB's using client-side dedup?
