I've a query in regards copies of databases, but specifically cloning test environments using VMWare, but even more specifically(!) employing linked clone feature of VMWare to copy & thus deduplicate test environments off the back of a snapshot standby database...environment is 11gR2 over RHEL5 EE.
For most test environments cut down copies are enough - however I'm looking to create copies of DBs but employing deduplication of master data, like EMC snapshots. Just wondering if anyone has achieved this with VMware linked clones off a snapshot of a virtual VM server? I know there are netapps cloning products available to do the same thing also.
