How to Restore Specific Files Non-Interactively

1. Become superuser.

2. Write-protect the tape for safety.

3. Insert the volume 1 tape into the tape drive.

4. Change to a directory for restoring files temporarily.

   # cd /var/tmp

   To avoid conflicts with other users, you might want to create and change to a subdirectory, such as /var/tmp/restore, in which to restore the files.

   If you are restoring a hierarchy, you should restore the files in a temporary directory on the same file system where the files will reside, so you can use the mv command to move the entire hierarchy where it belongs after it is restored.

5. Use the ufsrestore command to restore the file.

   # ufsrestore xvf /dev/rmt/n filename ...

   x	Tells ufsrestore to copy specific files or directories in the filename argument.
   v	Displays the file names as they are restored.
   f /dev/rmt/n	Identifies the tape device name.
   filename ...	One or more individual file or directory names separated by spaces, for example: ./export/home/user1/mail ./export/home/user2/mail.

6. Type the volume number where files are located and press Return.

   Specify next volume #: 1

   The file is restored to the current working directory.

7. To keep the mode of the current directory unchanged, type n and press Return at the set owner/mode prompt.

   set owner/mode for '.'? [yn] n

8. Verify the restored files.

   1. List the restored files and directories.

      # ls -l

      A list of files and directories is displayed.

   2. Check the list to be sure all the files and directories you specified in the list have been restored.

   3. Move the files to the proper directories.
