The dirmc option specifies the management class you want to use for directories.
If you do not specify this option to associate a management class with directories, the client program uses the management class in the active policy set of your policy domain with the longest retention period. Select a management class for individual directories that retains directories at least as long as it retains the files associated with them.
If you specify a management class with this option, all directories specified in a backup operation are bound to that management class.
The dirmc option specifies the management class of directories that you back up and it does not affect archived directories. Use the archmc option with the archive command to specify the available management class for your policy domain to which you want to bind your archived directories and files. If you do not use the archmc option, the server binds archived directories to the default management class. If the default management class has no archive copy group, the server binds archived directories to the management class with the shortest retention period.
This option is valid for all clients. The server can also define this option.
Place this option in the dsm.sys file within a server stanza. You can set this option on the Backup tab, Directory Management Class section in the Preferences editor.
Place this option in the client options file (dsm.opt). You can set this option on the Backup tab, Directory Management Class section in the Preferences editor.
