I am preparing to install Backup Exec 2010 R2 on a new server that will also have SQL 2008 installed. Is it better to install a new SQL 2005 Express instance with BU Exec, or use the existing SQL 2008 installation? The only direction I have found is in the Quick Installation Guide:
"When Backup Exec is installed into an existing instance, the automated master database restore feature is not available. To recover the Master database, replace it with the Master database copy that Backup Exec automatically creates and updates when the Master database is backed up. Caution: During the installation process and upgrade process, Backup Exec stops and starts the SQL service several times. Other user-created databases that use the SQL Server instance are unavailable during the process. To avoid such conflicts, you should install Backup Exec into its own SQL instance."
Are there any other considerations that help determine the best solution? Are there any reasons I shouldn't have SQL 2008 and SQL 2005 Express installed on the same server?
