Does unison replicates extended attributes? This is required. I haven't 
used unison for a long time, but when I'm right, it's not supported.

Bi-directional syncronisation would be nice. But how does it react, if a 
file was changed on DC A and B? Is always the newer replicated? Then 
some changes may getting lost. In that case I still would suggest, the 
editing should only be done on one DC.

Marc

Hai Marc, 

No, unison itself cant replicate the extended attributes. 
But you made a point thanks for that.

No, standard it does not, but you can use the copyprog  copyprogrest
copyquoterem to make this work with rsync.

The latest version is replicated, based on timestamp of the file.
But then this happend, then there is something very wrong. 

i've tested this, i can update gpo on server A or B, both end up the same in
folders and files.
with only the latest versions of the timestamp. 


So that said ..  ;-)  i have updated the script. 
Now its unison with rsync and the extended attributes are also copied. 

so now we have it...  
Bi directional sync, with rsync and unison. 
we need rsync for the directory structure to be created, 
for some reason this didnt work with the modified unison setup.  
so its a 2 setups sync, 1 rsync 2 unison. 

See the updated script :
https://secure.bazuin.nl/scripts/3-setup-sysvol-bidirectional-BETA.sh

Beta, testers are welkom.  ;-) 

Thank you Marc for pointing this out. 

Greetz, 

Louis
