In essence the ACE OBR is just a folder on the filesystem and the
repository.xml is dynamically recreated when something changes. ACE
OBR does not provide a feature to replicate, but any standard means
available to replicate that folder is an option.  For example a highly
available and/or replicated filesystem, rsync, or some custom
scripting. I guess it would be wise to exclude the repository.xml from
the replication set.

Then an ACE artifact is only loosely coupled to the OBR by means of an
absolute (resource) url. So if you have an ACE server with an artifact
that reference a resource by means of an url like
"" and host
fails you will have to switch that host to a standby server. Again,
there is no specific ACE feature but many options are available. For
example a checking loadbalancer, or a watchdog script and some dns
