SBS Backup Error Code 0x800710d8

Here's something to try if you have a consistent error of 0x800710d8 coming up in the SBS backup log.
Error code "0x800710d8" means "The object identifier does not represent a valid object."


This issue can occur if the internal Removable Storage Manager (RSM)
database is corrupted. This corruption prevents media pools from being
created or accessed. To resolve this issue, use the following method to
manually initialize an uncorrupted RSM database.


a. Start the Computer Management tool, double-click Services and
Applications, and then click Services.
b. Locate and stop the Removable Storage service (or change the startup
type from Automatic to Disabled), and then restart the computer.
c. Start Windows Explorer, open the %SystemRoot%\System32\Ntmsdata folder,
and then rename the existing files in this folder so that they have an .old
file extension, or copy the files to a different folder.
d. Restart the Removable Storage service (or change the startup type from
Disabled to Automatic), and then restart the computer.


After the RSM restarts, it creates a new database.
