To the best of my knowledge, DPM restores the entire DB and then picks out the appropriate piece you request for the restore.
From: [email protected] [mailto:[email protected]] On Behalf Of Daniel Chenault Sent: Wednesday, July 16, 2014 5:59 PM To: [email protected] Subject: [NTSysADM] DPM & Exchange I've not used DPM a lot (2012 installed here) but I have done brick-level restores with it. For some reason in this environment when I select a single mailbox it acts like it's going to restore just the one mailbox but in fact restores the whole database that holds the mailbox. To be clear: In DPM console go to Recovery: Search (open the leaf) Exchange Mailboxes. Use the dialogs at the top to find the one I want, then rclick, select "Recover" and follow the wizard. Recovery type: Recover mailbox to an Exchange server database Exchange server name is correct (selected from the Browse) as is the DB (a RDB created with PS). The mailbox I'm using is my own and on that date was about 12M. The recovery fails with "inadequate disk space" on a 400G drive. Uh.... what? I didn't set up the backup jobs; is there something that has to be configured there?
