anybody care to state system and command line used?

both are 2.5.2. But remember that while now I'm focusing on two machine,
the real situation is that only the machine doing the backup is  
capable of restoring from it.

Almost:

Large backup: can restore on OpenSuse only (the originator)
Small backups can restore on OpenSuse and Ubuntu (to be fair, this is  
not only smaller:
it is a different tree, there might be something in the filenames  
that upset somebody in the larger case).

getting the backup files with s3cmd, stuffing them in a directory and  
trying to restore
from the directory fails on both systems.

Tomorrow I'll try to reverse the roles, generate the backup on the  
Ubuntu machine and
try to restore on the OpenSuse machine.

Thanks again,
