File based replication can be configured between CrushFTP servers. CrushFTP uses a journaled file transfer system to make sure data changed on one server is changed the same way on both servers. Conflict scenarios should be very rare and difficult to achieve. However, we do not recommend the journaled system as the first choice method if you have a shared storage option available between servers. The journaled system should be the secondary choice when its necessary due to geographically distributed servers. The journaling and replication can *only* account for changes being made through CrushFTP. No outside processes can modify files, write to files, rename files, etc. All access needs to go through CrushFTP, or your journaled system will be out of sync requiring manual intervention to try and correct things.

Replication requires an enterprise level license, it is not available in normal licenses. Go to your preferences, Replication tab.

The items starting with "VFS" are what applies to this. The secondary server URL is the URL on the other CrushFTP server. So generally it will be "https://server2.com/".

The local server URL is a path locally that is the base location for all replication. This same exact path needs to exist on the opposite server.

The username and password is what will be used when authenticating to the other server to do file transfers. Typically a username like 'replication' is appropriate here. That user needs to exist on both servers, having the same access to the local folder defined in step 2.

The ping interval is how often to check if the server is online if there are pending journal items and the server is offline.

The VFS auto play function should be disabled for this. If its enabled, it will slow down user interaction with a server that is online if the opposite server is down.
