example of verifying
mt rewind
for path in $backupdirs
do
echo "Verifying $path...."
if tar tf /dev/nst0 1>/dev/null; then
echo "$path: verified" 1>&2
else
echo "$path: error(s) in verify" 1>&2
fi
mt fsf 1
done
don't know why everytime I cpio backuped to tape /dev/st0 not found.
and I need to close the console and reopen another one.
