I'm trying to add a second USB Hardisk Backup Destination to a new SBS2011 Server. When running wizard I always get the error "Cannot configure backup schedule".
Searching the Internet it appears this is a common issue with SBS2011 and the workaround is to use wbadmin. However, this also doesn't work.
After running wizard the following error is logged in the SBCW log.
The specified file path in the file spec does not exist. ---> Microsoft.SnapIns.Backup.UI.Proxy.BlockLevelBackupException: IBlbEngine::ModifyTemplate failed due to Blb error: EFileSpecNotFound (0x80780136)
When I Google this error, I cannot find a solution. Backup works fine to first USB drive and I always have both drives attached when I run wizard.
