OpenContrail 3.2: Create an instant backup of ZooKeeper¶

After you create a backup schedule as described in OpenContrail 3.2: Create a backup schedule for a ZooKeeper database, you may also need to create an instant backup of a ZooKeeper database on an OpenContrail 3.2 cluster.

To create an instant backup of a ZooKeeper database:

1. Verify that you have completed the steps described in OpenContrail 3.2: Create a backup schedule for a ZooKeeper database.

2. Find out which OpenContrail control node is the ZooKeeper leader.

   salt -C 'I@opencontrail:control' cmd.run 'echo stat | nc localhost 2181 | grep leader'
   

3. Log in to the OpenContrail control leader node, for example, ntw01.

4. Run the following script:

   /usr/local/bin/zookeeper-backup-runner.sh
   

5. Verify that a complete backup has been created on the OpenContrail control leader node:

   ls /var/backups/zookeeper/full
   

6. Log in to the zookeeper server node and verify that the complete backup was rsynced to this node by executing the following command:

   ls /var/backups/zookeeper/full
