Actually, LDAP server is down during backup of the machine that runs it 
because the server itself is backed up (settings, database, ...).
But second backup (faulty one) won't never ever touch it, except for Uname 
resolution (read only access). Thus I don't think it is a problem if it is 
running during this particular one.

On my side I think is that it could work. Even it should work if option 
description in the manual is correct. ;-)
That's why I want to try it. Actually I will then time shift one of the 
backup, but keep this option as a "safety option" if it works.

Fact that you enjoy helping people like me is not a sufficient thing so I 
don't have to thank you. :-)

I mistook my test on past night. I will take some days to perform some 
different tests.
Then I will come back to you with an updated clear and complete status 
about what helps and what don't in situations like mine (expect update end 
of this week/beginning of next).

See you,
