Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide

The Dfsbackupmntpnt Option

By default, Tivoli Storage Manager DFS file backup clients do not cross DFS mount points. The DFS mount points and symbolic links require similar backups. For example, if you define /.../xyz-cell/fs/u/foo as a Tivoli Storage Manager virtual mount point and you enter this command:

   incremental /.../xyz-cell/fs/u/foo

Tivoli Storage Manager performs the following incremental backup for /foo:

  1. Backs up any files under /foo that are eligible for backup.
  2. Backs up directories under /foo that are not DFS mount points.
  3. Backs up mount point information for any DFS mount point under/foo.
Note: Tivoli Storage Manager does not process files or subdirectories under any DFS mount point it encounters under /foo. Processing stops at each mount point.

If you want the file backup clients to cross DFS mount points, set the dfsbackupmntpnt option to no. Tivoli Storage Manager backs up the mount point as a directory rather than as a symbolic link to the target fileset. For more information about the dfsbackupmntpnt option, see Dfsbackupmntpnt.

When you use the archive client, the directory that is pointed to by the mount point is archived.
