Full Discussion: tar - restore a file
Operating Systems Solaris tar - restore a file Post 46252 by RTM on Monday 12th of January 2004 09:15:51 AM

Check your man pages for your version of OS (since you did not post it)

You can try after checking how it was listed in the tar (see below)
# cd /tmp
# tar -xf /dev/rmt/0n ./mydir/myfile

You must see how your file was backed up - if it's ./mydir/myfile then you can put it in a new directory (all the mydir directories above it will be created under whichever directory you are in).
If it's listed as /mydir/myfile, then it's going to restore the file in the original directory - so you must do the restore on a different system to avoid overwriting the file. Use the tar -tvf /dev/rmt/0n to view what is on the tape (change /dev/rmt/0n to what ever your tape drive is)

amverify

AMVERIFY(8)						      System Manager's Manual						       AMVERIFY(8)

NAME

       amverify - check an Amanda tape for errors

SYNOPSIS

       amverify config [ slot [ runtapes ] ]

DESCRIPTION

       Amverify  reads	an  Amanda  format  tape  and makes sure each backup image can be processed by amrestore and, if possible, the appropriate
       restore program (e.g. tar).

       Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a  cata-
       logue of the backup.  The catalogue itself is discarded.  Only the success or failure of the operation itself is reported.

       If  the	backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent
       through dd to /dev/null.  This still determines if the tape is readable, but does not do any internal consistency check on the image.

       If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process.  Otherwise, the current  slot
       is used.

       The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line.

       See the amanda(8) man page for more details about Amanda.
