filesystem retoration and removal of files

[absi]

hi all,
we have a filesystem backup in week by tar
command....this filesystem have app codes
which are usually updated frequently by programmers.
when we restore the backup the unneccessary
files remain there and only updated files are
overwritten.
Is there anyway to remove those files which are
not in backup tape automatically during resoration
by tar command.
At this time we first run rm -r command on fs
and then use tar -xvf command.
Help will be highly appreciated!!!!

Why not write a script based around the -t option tar to obtain a listing - then compare it against the directory; delete all files not in the list.

Just an idea.

Nice idea ...
i think it will work!!!!
But strangely why traditional unix tar command
does not provide any flag for that purpose.
Or there is some other command for this purpose?
