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:

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

This displays the XDCR Replications screen. The lower part of the main panel, entitled Remote Clusters, features and Ongoing Replications panel that currently has the following appearance:

This features information on a single, currently defined replication. In the status column, this replication is shown to be Paused.
To resume the replication, left-click on the start symbol provided:

The start symbol changes back to a pause symbol, and the word Paused changes to Replicating:

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.

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