This topic describes how to backup important files on your host before upgrading the operating system.

Backing Up

  1. Create a top-level backup directory.
    export CM_BACKUP_DIR="`date +%F`-CM"
    echo $CM_BACKUP_DIR
    mkdir -p $CM_BACKUP_DIR
  2. Back up the Agent directory and the runtime state.
    sudo -E tar -cf $CM_BACKUP_DIR/cloudera-scm-agent.tar --exclude=*.sock /etc/cloudera-scm-agent /etc/default/cloudera-scm-agent /var/run/cloudera-scm-agent /var/lib/cloudera-scm-agent
  3. Back up the Cloudera Manager Server directories:
    sudo -E tar -cf $CM_BACKUP_DIR/cloudera-scm-server.tar /etc/cloudera-scm-server /etc/default/cloudera-scm-server
  4. Back up the Cloudera Manager databases. See Backing up Cloudera Manager databases
