Murthy, There are several client options that you can use which involves utilizing links.
TSM History for links (UNIX Clients Manual) TSM handles symbolic links differently than it does regular files and directories. In some operations, such as a backup, only the path information that the symbolic link contains is backed up. In other operations, such as archive, the file to which the symbolic link points is archived, but under the name of the symbolic link. For directories, most operations are affected by the setting of the subdir option. If the subdir option is set to no , only the directory and the files it contains are affected. If the subdir option is yes , TSM recursively processes all files and directories in the directory tree. Incremental backup - When you run an incremental backup, TSM backs up only the path information to a file or directory to which a symbolic link points. The contents of the file or the contents of files in the directory are not backed up. Selective backup - When you run a selective backup on a symbolic link that points to a file, TSM backs up only the path information to that file. The contents of the file are not backed up. Restore - When you restore a symbolic link that originally pointed to a file, the symbolic link is restored, whether or not the file it points to still exists. If you restore a symbolic link that originally pointed to a directory: �Without the files in the directory (for example, /home/gillis/symdir/), and the symbolic link does not exist on your file system, nothing is returned. Along with the files in the directory (for example, /home/gillis/symdir/*), and the symbolic link does not exist on your file system, TSM builds the directory on your workstation and puts the files in that directory. If the subdir option is set to yes , TSM recursively restores all subdirectories of the directory. �And the symbolic link already exists on your workstation, the result depends on how the followsymbolic option is set; if it is set to: Yes - The symbolic link is restored and overwrites the directory on your workstation. If the followsymbolic option is set to yes , a symbolic link can be used as a virtual mount point. No - TSM displays an error message. No is the default. The archsymlinkasfile option specifies whether TSM follows a symbolic link and archives the file or directory it points to, or archives the symbolic link only. Use this option with the archive command. (THIS IS THE DEFAULT IN TSM 4.2 UNIX CLIENTS) The followsymbolic option is used to restore to a symbolic link (that is a virtual mount point) and is unrelated to the archsymlinkasfile option. Hope this helps a bit!!!

I need to backup a directory with nothing but softlinks pointing to some directories. I have set the subdir option in the dsm.opt file as given below. SUbdir YES I have selected the directory in the GUI for a Incremental(Complete) But it does not process the link to take backup of the directories the links point to. It just takes backup of only the links. How do i make the TSM client backup the directories the links point to. Also is there a way i can stop the TSM client from backing up hardlinked files. Help in understanding how Hard & Soft links are processed would be greatly appreciated. Thanks in Advance murthy V S Murthy Gongala Bangalore, INDIA Tel : 91-80-5094232
