Enterprise Vault automatically synchronizes archive permissions with folder permissions. When Enterprise Vault archives files, the version stored in the archive is given the same permissions as the folder that contained the original file.
This means the following:
If there is a file with permissions that are different from those of the containing folder, the archived version has the folder permissions. A shortcut has the same permissions as the file.
Someone who has access to the original folder can find and access the archived version of the file, even if the file permissions denied access. Such a person cannot use a shortcut to access the file, however.
Synchronization can be configured on the Synchronization tab in the properties of the File System Archiving task. Synchronization runs a maximum of twice each day and always runs until completion.
