Exchange admins who are/were backing up Exchange 2007 servers using Data Protection Manager (DPM) 2007 should have come across the issues of expanding the volumes used for backups manually and to perform a consistency check manually whenever the data was in an inconsistent state.

Guess what? Those two issues have been fixed in DPM 2010 RC. The two options are enabled by default when you create a protection group in DPM 2010.

1. Automatically grow the volume when more disk space is required for protecting the items in the protection group.

2. Run a consistency check if the replica become inconsistent.

Consistency Check

A welcome fix indeed!
