Synchronization of a database with the previously noted methods happens only once, at the time the replicate request is made. To have the target database permanently replicated from the source, you must set the continuous field of the JSON object within the request to true.

With continuous replication changes in the source database are replicated to the target database in perpetuity until you specifically request that replication ceases.

POST http://couchdb:5984/_replicate
Content-Type: application/json
Accept: application/json

{
   "continuous" : true
   "source" : "recipes",
   "target" : "http://couchdb-remote:5984/recipes",
}

Changes will be replicated between the two databases as long as a network connection is available between the two instances.
