restore function

Ragni Singh — Tue, 03 Feb 2004 15:57:09 GMT

Hello all,

I have used the dump command to backup data to a tape but am in a big dilemma now. How can I use the restore option to restore a particular dir from tape. I would like to restore /var/opt/testing from tape. Any help is greatly appreciated and points will be assigned.

You have to use the dd command to read from /dev/rmt/0m

Sanjay,

I used dump long time back. So, I am dependent on the man pages now.

With -x option, you should be able to restore an individual directory. The man page of 'restore' says

//

x Extract the named files from the tape. If the named file
matches a directory whose contents had been written onto
the tape, and the h modifier is not specified, the
directory is recursively extracted. The owner,
modification time, and mode are restored (if possible). If
no file argument is given, the root directory is extracted,
which results in the entire contents of the tape being
extracted, unless h has been specified. //

What is the problem you have?

Hi,
I never uses dump/restore myself but a look at the man page says you should use the x option. See man page for restore.

This is what I keep getting..

# restore -x /etc/hosts
Note: Doing Quad swapping
You have not read any tapes yet.
Unless you know which volume your file(s) are on you should start
with the last volume and work towards the first.

It should, after that point, say
"Specify next volume #:"

At which point, if you don't know which tape the file is on,
you will enter "1" (without quotes) then press enter.

Note that you may want to try without specifying the path:

# cd /desired_directory_here
# restore -xv name_of_file
(Enter 1 when it asks for volume number, then y for next question)

If that doesn't work, see if the path is different than "./"

# restore -tv |grep name_of_file
