Hello,
A media vault is a logical representation of the actual physical location of media. You can create user-defined media vaults to keep track of where media is physically stored, such as a special media room, a scratch bin, or an off-site location. For example, you could create a media vault where media to be sent off-site is moved, then print the media vault contents report, which lists the media contained in that vault, to accompany the physical media to its off-site storage.
