My environment is about 90% virtualized running Hyper-V 2008 R2. I have about 300 users. Currently my backup solution is to backup the virtuals using Symantec Back up Exec. I'm planning to perform a disaster recover test in a couple of weeks and would like to know if I should expect any issues with restoring the .vhd files of each of these systems (Active Directory, Sharepoint 2010, SQL 2005 & 2008, Exchange 2010). Creating new virtuals in the DR environment and mounting the .vhds repectively?
