Restore Usage

From Gruff Goat Wiki

Restore files and filesystems saved with dump. Learn more with 'man restore'.

Rebuild

To rebuild a filesystem, it is best to start clean. Start clean with the command newfs. For example, a server has the mount point /home at /dev/idad0s1g.

umount /home
newfs /dev/idad0s1g
mount /dev/idad0s1g /home
cd /home
restore -rf /backup/dump_level_0
restore -rf /backup/dump_level_1
restore -rf /backup/dump_level_2
# Do until all dump levels are restored
rm restoresymtable
cd /

Interactive

An interactive restore allows you to select which files or directories to restore. Use this command to restore files to an already populated directory. To restore files to the mount point /home, follow the example

cd /home
restore -if /backup/dump_level_0

Once you are in restore interactive there are a number of commands you may use. Enter 'help' to get a list of commands. Add the files or directories you wish to extract. Wildcards are acceptable. When done adding, extract the files into the filesystem. For example:

ls              # List directory contents
cd export       # Change to the export directory
add mine        # Add the file or directory named export
cd /
add *           # Add all files and directories in the present directory
delete notmine  # Remove notmine from the extraction
extract         # extract the selected files

The restore process begins after you answer 2 question.

Specify next volume #:          1
set owner/mode for '.'? [yn]    n

Verify that all worked as expected.
