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.

Best Regards

Daniel

Ärende: [ADSM-L] Dedup for DB's?


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?
