[Bug-tar] Possible Bug?

I'm using GNU tar version 1.20 for executing incremental backups.

I don't dare to flag it as a bug but I'm a little bit confused with the
following use case so that any help will be very appreciated.

I have the following hierarchy:


First, I perform a backup:

tar -cpvzf  tarfile -g snapshot_1

then I change the name of directory "dir_1" to "dir_1_new", and I perform a
new incremental backup.

The problem appears when restoring. The first backup is restored ok, but
when restoring the second, tar cannot rename the directory "dir_1" because
it's not empty.

Is this the expected behaviour? And if so, is there any way to "force" tar
to rename also not empty directories (some tar option or whatever)?

Thanks in advance!
