It seems that John has helped a lot. I just share 2 blogs that
I think is related with your issue.<br>

have another stupid question - after all is said and
done, how many copies of my data will I have?! What I am
aiming for is something like 2 regions and 3 replicas
ie, 2 copies of the data in region one and one copy in
region 2.<br>

good blog posts and videos that could show/explain what
I am trying to do. I have Juno setup and it working
great (thanks to everyone on heres help)! Now, I would
like to add two more Object Store nodes, but as a
separate "datacenter" as it were and replicate between
my existing ring and the new one. Now, Im not sure
exactly what to do for the account/container/object
rings and how to get them to replicate (so if one goes
down the other will still continue to serve data). I am
also going to try and add another storage node just as a
backup for existing data. Would anyone have any good
links to send me I would appreciate it!<br>
