Issue
Vista appears to run normally, but when creating a backup using the $backup_VDB object no backup is created. The message "Unable to copy $thisdb\*.*" appears in b0cfglog.txt in the $log folder, but there are no other indications that the backup has failed.
Environment
TAC Vista 5
Cause
An additional folder has been placed in the $thisdb folder, possibly while manually copying or moving the database. The folder name is not important, but any change in the internal structure of $thisdb prevents Vista from taking a backup. Additional files in $thisdb do not have this problem.
Resolution
Delete any sub-folders from the $thisdb folder.
