samba - Apr 2009 - How to make fully working samba backup/migration?

Hello,

how to correctly make full and fully working samba backup?
I read articles and newsgroups seeing how many people failed because something 
was forgotten to be copied or saved and restored/merged.
Usually password and user accounts does not work.
What I found is most people copy:
/etc/samba
the smarter copy also:
/home
geeks knows they should also copy:
/etc/passwd
/etc/shadow
/etc/groups
and
/var/lib/samba
where tdb files are kept.

Looking at these gathered files I think I should also store file rights and 
user/owner of each file. Finally I should merge:
/etc/passwd
/etc/shadow
/etc/groups
on new system with these I backed up from older system.

How to copy files from users' accounts at /home/* if files created by M$ 
Windows have characters in file names Linux can not handle during copy? How to 
preserve windows file rights when migrating samba from Linux to Linux?

I hope I identified all problems which may happen... If not tell me what I 
missed and tell me how to fix such problem.

Did I miss something or this is full list of operations to be done to have 
fully working samba backup?

have a nice day,
zbiggy

Hello,
I have never been migrating a working samba to another computer, but
we have been many times transferring data from host to host during
migrations and "rsync" was the best tool available. Take a look on the
option "-a, --archive               archive mode; equals -rlptgoD (no
-H,-A,-X)".
The same "archive" mode you will find in cp and others. I do not
_know_ how ACLs are handled in this case, but I think it's an easy
thing to check.

Regards,
Michal
