Resume a Replication

    +
    After an XDCR replication has been paused, resuming it restarts the replication of data from the source bucket to the target.

    Examples on This Page

    The examples in the subsections below show how to resume a replication; using the UI, the CLI, and the REST API respectively. As their starting-point, the examples assume the scenario that concluded the page Pause a Replication.

    Resume an XDCR Replication with the UI

    Proceed as follows:

    1. Access Couchbase Web Console. Left-click on the XDCR tab, in the right-hand navigation menu.

      left click on xdcr tab

      This displays the XDCR Replications screen. The lower part of the main panel features an Outgoing Replications panel that currently has the following appearance:

      xdcr outgoing replications panel replication paused

      This features information on a single, currently defined replication. In the status column, this replication is shown to be paused, and a Run button is displayed.

    2. To resume the replication, left-click on the Run button:

      xdcr left click on resume replication button before

      The word paused changes to replicating, and the Run button is again displayed as a Pause button.

      xdcr resume replication button after

    Replication has now been resumed.

    Resume an XDCR Replication with the CLI

    From the starting-point defined above, in Examples on This Page, use the CLI xdcr-replicate command with the --resume flag, to pause an XDCR replication as follows:

    couchbase-cli xdcr-replicate -c 10.142.180.101 \
-u Administrator \
-p password \
--resume \
--xdcr-replicator=570d0ca2db3b1e128e2fafd362a1bfd4/travel-sample/travel-sample

    The value specified for the --xdcr-replicator flag is that retrieved by means of the --list flag, shown in Pause an XDCR Replication with the CLI.

    If successful, the command returns the following:

    SUCCESS: XDCR replication resume

    Replication has now been resumed.

    Resume an XDCR Replication with the REST API

    From the starting-point defined above, in Examples on This Page, use the REST API to resume an XDCR replication as follows.

    curl -X POST -u Administrator:password \
http://10.142.180.101:8091/settings/replications/570d0ca2db3b1e128e2fafd362a1bfd4%2Ftravel-sample%2Ftravel-sample \
-d pauseRequested=false

    The endpoint used here features, in sequence, the id of the reference, the name of the source bucket, and the name of the remote bucket. These were obtained in Pause an XDCR Replication with the REST API. The value of the pauseRequested flag is here set to false.

    The output is as follows:

    {
  "checkpointInterval": 600,
  "compressionType": "Auto",
  "docBatchSizeKb": 2048,
  "failureRestartInterval": 10,
  "filterExpression": "",
  "logLevel": "Info",
  "networkUsageLimit": 0,
  "optimisticReplicationThreshold": 256,
  "pauseRequested": false,
  "sourceNozzlePerNode": 2,
  "statsInterval": 1000,
  "targetNozzlePerNode": 2,
  "type": "xmem",
  "workerBatchSize": 500
}

    Replication has now been restarted.

    Next Steps

    Once a replication is no longer needed, you can delete it. See Delete a Replication.
