Back up and restore a ZooKeeper database

Back up and restore a ZooKeeper databaseΒΆ

MCP uses a custom script to back up a ZooKeeper database. ZooKeeper is a part of every OpenContrail deployment and the backup utility includes the following components:

  • ZooKeeper server stores ZooKeeper backups rsynced from the ZooKeeper client nodes and runs on any node, for example, the Salt Master node.
  • ZooKeeper client sends database backups to the ZooKeeper server and always runs on all the nodes of the ZooKeeper cluster. However, the back up is performed only on the leader node.

This section describes how to create and restore the ZooKeeper cluster on your OpenContrail 3.2 or 4.x cluster.
