When the Archiving Task walks through the target file system and processes existing Archive Points and Folder Points, it has the ability to detect unexpected Archive Points, therefore reporting an event warning.
Source: Enterprise Vault
Category: File System Archiving Task
Duplicate archive point: '\\?\UNC\evserver.ev.local\D$\evdepartment\evshare'.
The original folder and its archive point have been copied.
This folder and its subfolders will not be archived until this situation is resolved.
Refer to the documentation for more information.
The File System Archiving (FSA) Task reports the above event if it finds duplicate or foreign Archive Points in the target folder structure being processed. This could be caused by moving or copying a folder containing an Archive Point to a different storage location or the folder structure of an Archive Point being restored from backup to a redirected location.
