SCCM 2012: Site Backup failed
August 10, 2012

Issue: I was trying to configure site backup Maintenance Task to put backup to a hidden share on my SCCM server. I am using a SQL Cluster as a backend. The backup failed with the error:
Error: Backup folder <My BackupFolder> does not exist or backup service does not have permission to access the folder.
Error: SQL Server could not prepare for the Backup.
Resolution: Максимов Алексей pointed me to a fresh Microsoft link: http://blogs.technet.com/b/configurationmgr/archive/2012/08/01/support-tip-a-backup-site-server-maintenance-task-may-fail-to-run-in-configmgr-2012.aspx
It turned out to be a known bug with SCCM 2012 (probably will be fixed with SP1).
There are several workarounds suggested – I used one recommended to create a Backup Share on SQL, not on ConfigMgr.
