To restore a dump file by overwriting an existing fileset, do the following:
1. Verify that you have the necessary privileges. You must be included in the admin.ft file on the machine on which the fileset is to be stored, and you must be included in the admin.fl file on each Fileset Database machine or own the server entry for each machine on which a version of the fileset to be overwritten is stored. If necessary, issue the bos lsadmin command to verify the members of an administrative list.
2. Verify that you have the r (read) ACL permission for the dump file. If necessary, issue the dcecp acl show command to list the permissions for the file.
3. Enter the fts restore command to restore the dump file over an existing read/write fileset, using the -overwrite option to overwrite the current contents of the fileset:
$ fts restore -ftname name -server machine -aggregate name [-file filename] [-ftid ID] [-overwrite]
The -ftname name option specifies the name of the fileset that is to be overwritten.
The -file filename option specifies the complete path name of the file that is to be restored. The current working directory is used if a complete path name is not provided. If this option is omitted, the data is read from standard input (stdin).
The -ftid ID option specifies the fileset ID number that is to be assigned to the fileset. If this option is omitted, the current ID number of the existing fileset is retained. Use this option with great care; make sure the fileset ID number you specify is not in use. Use this option only when restoring a dump file as a DCE LFS fileset; omit this option when restoring a dump file as a non-LFS fileset.
The -overwrite option specifies that the restored fileset can overwrite an existing fileset. If this option is omitted, the command refuses to overwrite an existing fileset. You must use this option to overwrite a previously restored version of a fileset with a dump file that contains an incremental dump of the same fileset or to restore a dump file as a non-LFS fileset.
4. If read-only copies of the former read/write fileset exist, use the fts update command to replace them with replicas of the new fileset. If a backup version exists, use the fts clone command to replace it with a backup version of the new fileset.
