Backing up and Restoring Files

# P0602484 Ver: 2.7 Page 141

The example above uses the “n” option to stop the tape from rewinding. This allows

each dump to be stacked on a single tape. To use a separate tape for each dump,

remove the “n” and at the end of each dump replace the tape.

5. Rewind the tape. When all dumping for this particular tape is com-

plete, rewind the tape with:

# mt -f /dev/rmt/0 rew

6. Eject the tape and label the cover. Write the date, hostname, and

slice dump order on the label, and store the tape and partition table

information in a safe and accessible location.

7. Additional backups. If necessary, continue dumping to additional

tapes. The following is an example for dumping an MMFdisk:

# ufsdump 0ucf /dev/rmt/0 /dev/rdsk/c0t0d0s1

Displaying the Contents of a ufsdump Backup

Display the table of contents for each backup to ensure that it is readable and

complete, and that a particular media volume contains the files and/or directories to be

extracted.

How to ...Display the Contents of a ufsdump Backup

1. Insert the backup media into the appropriate drive.

2. Log in as root.

a. From any command line enter su.

b. Enter the root password (____________).

3. Enter the ufsrestore command with the following options:

• To verify the contents of a tape directly, enter ufsrestore tf

/dev/rmt/0. By not supplying any file names, the root direc-

tory is listed, resulting in a list of all files on the media.

• To verify the contents of a tape that was backed up with the

archive file option, enter ufsrestore taf

<archive_file> /dev/rmt/0

• To verify the contents of other media, substitute that media

device name for /dev/rmt/0 in the above examples.

These commands verify each file stored in the archive file and prints its

name to the screen.
