SBS 2003 backup error

The SBS 2003 backup that I was using at night recently did not succeed. I am also getting the below error code and cannot understand what this really means:

GetNtmsObjectInformation(NtmsLibraryInfo) succeeded.
Found an enabled library.
InventoryNtmsLibrary(NtmsInventoryOmid) succeeded.
GetTapeMediaPoolName failed. (0x800710d8)
GetBackupDestination failed. (0x800710d8)
LaunchNTBackup failed. (0x800710d8)
NTBackup finished the backup with errors.

For more information about failed backups, see the article on troubleshooting your backup at the following Web page: http://go.microsoft.com/fwlink/?LinkId=18414

Can anyone please help me out? Thanks.

The problem that you are facing can occur if the internal Removable Storage Manager (RSM) database is corrupted. This corruption prevents media pools from being created or accessed. If you have never performed a %SystemRoot% backup using Windows 2000 Backup, the %SystemRoot%\System32\Ntmsdata\Export folder does not exist. In this case, force the RSM to create a new database by following the method given here - http://support.microsoft.com/kb/288856/en-us
