Chapter 7. Backing up important files

Procedure

1. Log in to a hyperconverged host as the root user.

2. Change into the hc-ansible-deployment directory and back up the default archive_config_inventory.yml file.

   # cd /etc/ansible/roles/gluster.ansible/playbooks/hc-ansible-deployment
   # cp archive_config_inventory.yml archive_config_inventory.yml.bk

3. Edit the archive_config_inventory.yml file with details of the cluster you want to back up.

   hosts

   The backend FQDN of each host in the cluster that you want to back up.

   backup_dir

   The directory in which to store backup files.

   nbde_setup

   If you use Network-Bound Disk Encryption, set this to true. Otherwise, set to false.

   upgrade

   Set to false.

   For example:

   all:
     hosts:
       host1-backend.example.com:
       host2-backend.example.com:
       host3-backend.example.com:
     vars:
       backup_dir: /rhhi-backup
       nbde_setup: true
       upgrade: false

4. Run the archive_config.yml playbook using your updated inventory file with the backupfiles tag.

   # ansible-playbook -i archive_config_inventory.yml archive_config.yml --tags=backupfiles

   This creates an archive in the /root directory specific to each host FQDN in the hosts section of the inventory, for example, /root/rhvh-node-host1-backend.example.com-backup.tar.gz.

5. Transfer the backup archives to a different machine.

   # scp /root/rhvh-node-host1-backend.example.com-backup.tar.gz backup-host.example.com:/backups/
