Had an issues where a SCCM 2012 Primary Site did want to install/re-install the SMS_SITE_SQL_BACKUP_[SITESERVER-FQDN] component. Got errors that the Installation path did not exist.This was easy to correct.
- Change the string named value “Installation Directory” in the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftSMSComponentsSMS_SITE_COMPONENT_MANAGERMultisite Component Servers[DB-SERVER-FQDN] with [DB-SERVER-FQDN] being the placeholder for the FQDN of the database server hosting the site server’s database (so for example, the last level in the key path is named “SRV02.DOMAINCOMPANY.COM” if your site server’s database server is named “SRV02” and your domain “DOMAINCOMPANY.COM”). Typically it’s only the drive letter that has to be adapted, although that depends on how much of the location has been changed (as said before you can change whole pieces of the path).
- Restart the Windows service “SMS_SITE_COMPONENT_MANAGER” on the site server so the change is read in and becomes active.
- Restart the SCCM console. Refreshing or changing the node in the console doesn’t update the storage object in the Site Status “view”
