ProcedureHow to Restore Specific UFS Files Noninteractively

  1. Become superuser or assume an equivalent role.

  2. (Optional) Write-protect the tape for safety.

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

  4. Change to a directory that will be used to restore files to temporarily.

    # cd /var/tmp
  5. Restore the file or files.

    # ufsrestore xvf /dev/rmt/n filename

    Tells ufsrestore to copy specific files or directories in the filename argument.


    Displays the file names as they are restored.

    f /dev/rmt/n

    Identifies the tape device name.


    Specifies one or more file names 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. Press Return.

    Specify next volume #: 1

    The file or files are restored to the current working directory.

  7. To maintain the mode of the current directory, 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 that all the files and directories you specified in the list have been restored.

  9. Move the files to the proper directories.

Example 26–4 Restoring Files From a Remote Tape Device

You can restore files from a remote tape drive by adding remote-host: to the front of the tape device name, when using the ufsrestore command.

The following example shows how to restore files by using a remote tape drive /dev/rmt/0 on the system venus.

# ufsrestore xf venus:/dev/rmt/0 ./etc/hosts
