Thanks for answering the thread Luigi. I have a couple more followup questions :
I downloaded orientdb release 2 M2. I could not find orientdb-dserver-config.xml in the config directory. The 1.7.9 version has it though. Am I missing something in the release 2 M2 version ? Also, are you planning to have a backup to file system ( not snapshot) and without blocking writes in a future release ?
