For every media server, you should add an entry on the Alternate Media Server Names tab of the Vault Management Properties dialog box. At a minimum, there should be, for each media server, an entry that contains both the abbreviated name and the fully qualified name. Also add any other names by which a media server has ever been known. Taking this action will avoid a number of problems. For example, if you do not list alternate names for media servers, some images may not be recognized as a match for the criteria entered in the Choose Backups tab of the Profile dialog box and may therefore not get vaulted.
