Backing up NFS file systemsvvNAS nodes represent a new node type. The NAS node name uniquely identifiesa NAS file server <strong>and</strong> its data to <strong>Tivoli</strong> <strong>Storage</strong> <strong>Manager</strong>. You can prefix the NASnode name to the file specification to specify the file server to which the includestatement applies. If you do not specify a NAS node name, the file system youspecify applies to all NAS file servers.Regardless of client plat<strong>for</strong>m, NAS file system specifications use the <strong>for</strong>wardslash (/) separator, as in this example: /vol/vol0.Note: When you initiate a NAS backup operation using the comm<strong>and</strong> line client,GUI client, or Web client the server starts a process to initiate, control, <strong>and</strong> monitorthe operation. It might take several moments be<strong>for</strong>e you notice progress at thecomm<strong>and</strong> line client interface because the server must per<strong>for</strong>m mount <strong>and</strong> othernecessary tasks be<strong>for</strong>e data movement occurs.Related reference“Toc” on page 423Use the toc option with the backup nas comm<strong>and</strong> or the include.fs.nas option tospecify whether <strong>Tivoli</strong> <strong>Storage</strong> <strong>Manager</strong> saves table of contents (TOC) in<strong>for</strong>mation<strong>for</strong> each file system backup.The <strong>Tivoli</strong> <strong>Storage</strong> <strong>Manager</strong> <strong>Backup</strong>-<strong>Archive</strong> client can be configured to protectfiles which are accessed with the Network File System (NFS) protocol. While betterbackup throughput per<strong>for</strong>mance can be realized by installing the <strong>Backup</strong>-<strong>Archive</strong>client where the file system physically resides, it is sometimes necessary to accessfile systems using NFS <strong>for</strong> purposes of backup <strong>and</strong> recovery. The <strong>Tivoli</strong> <strong>Storage</strong><strong>Manager</strong> <strong>UNIX</strong> <strong>and</strong> <strong>Linux</strong> <strong>Backup</strong>-<strong>Archive</strong> client can back up, archive, restore <strong>and</strong>retrieve file data using an NFS mount. This includes all versions of the NFSprotocol, including NFS version 2, NFS version 3, <strong>and</strong> NFS version 4.The NFS version 4 protocol allows <strong>for</strong> the export of access control lists (ACL) withNFS. As shown in the following table, some of the <strong>Backup</strong>-<strong>Archive</strong> clients providesupport to back up <strong>and</strong> restore ACL in<strong>for</strong>mation on data accessed using NFS. Notethat the NFS version 4 protocol must be installed on both the NFS client <strong>and</strong> NFSserver in order to backup <strong>and</strong> restore ACL data.Table 34.
