Because I can, this blog will be used for whatever I want.

I have spent the last few hours fighting with Backup Exec System Recovery, trying to perform a physical-to-virtual conversion of a Windows Server 2003 machine on a Server 2008 R2 machine. It kept giving a few errors relating to an inability to mount the backup file. The BESR event log showed the following:

Error EC8F1F48: The 'Microsoft VHD' conversion process could not be completed.
Error EC8F1F44: Cannot mount recovery point 'D:\Backups\ZDRW-TS\_C\_Drive001.v2i'.
Error E98F0032: RPAM failed to mount image.  
Error EBAB03F1: No more data is available. (UMI:V-281-3215-8008)

Wonderfully descriptive! Windows event log showed nothing. Symantec’s KB suggested that something was interfering with the backup process but I discovered I was able to mount them using the Recovery Point Browser, suggesting that the recovery point was fine. Odd. There was nothing installed on the server other than BESR and some basic Windows roles, nothing that would interfere with the process. So what would stop it from converting? What was running on the server that could possibly interfere with the operation of a program?

UAC. Disabled, rebooted, tested. Fixed. No documentation about this anywhere. Hopefully it will help someone else!
