'Moodle asynchronous replication
I'm looking to deploy moodle in the cloud however I have some 50 odd sites which require access to this moodle possibly even temporarily offline. So I'm looking into replicating moodle down onto each site. From what I understand there are 2 data stores that require replication, moodledata and the database, postgresql in our case. moodledata if I'm not mistaken contains the multimedia data and the database among other things all the user records. Luckily the multimedia data will be centralized and is thus synched only one way down to the nodes, that seems doable. Where I'm stuck is how do I handle the Postgres database where the sync will need to be bidirectional?
