note

Commands are provided below to backup various files and directories used by Cloudera Manager Agents. If you have configured custom paths for any of these, substitute those paths in the commands. The commands also provide destination paths to store the backups, defined by the environment variable CM_BACKUP_DIR, which is used in all the backup commands. You may change these destination paths in the command as needed for your deployment.

The tar commands in the steps below may return the following message. It is safe to ignore this message:

tar: Removing leading `/' from member names

Create a top-level backup directory.

export CM_BACKUP_DIR="`date +%F`-CM"
echo $CM_BACKUP_DIR
mkdir -p $CM_BACKUP_DIR

1. Back up the Cloudera Manager Server directories along with the CSP key file when Credential Storage Provider (CSP) is enabled:
```
sudo -E tar -cf $CM_BACKUP_DIR/cloudera-scm-server.tar /etc/cloudera-scm-server /etc/default/cloudera-scm-server ***/path/to/csp/keys***
```
  important
  In the above command, you must replace the ***/path/to/csp/key*** with the actual path where the CSP key has been stored from the following options:
  - /var/lib/cloudera-scm-server/csp-data
  - /opt/cloudera/
  - /etc/cloudera/
  - /var/cloudera/
2. Back up the Cloudera Manager Server directories without CSP key file:
```
sudo -E tar -cf $CM_BACKUP_DIR/cloudera-scm-server.tar /etc/cloudera-scm-server /etc/default/cloudera-scm-server
```

Back up the existing repository directory.

SLES

sudo -E tar -cf $CM_BACKUP_DIR/repository.tar /etc/zypp/repos.d
