A VOB hosted on a computer running Linux® or the UNIX® system can have one or more of its storage pools on a remote host running Linux or the UNIX system, accessed through a symbolic link. If you move a VOB with this configuration to a NAS device, you may want to consolidate the remote pools by replacing the symbolic links with local directories. You do not need to consolidate the remote pools as long as they are accessible to the VOB server host, but doing so simplifies VOB backups and other administrative tasks. See Consolidating remote pools.
