|
#
|
|
# ansible-playbook -i <inventory> backup-and-restore-ceph-files.yml -e backup_dir=<backup directory path> -e mode=<backup|restore> -e target_node=<inventory_name>
|
|
#
|
|
# Required run-time variables
|
|
# ------------------
|
|
# backup_dir : a path where files will be read|write.

|
# --------
|
|
# ansible-playbook -i hosts, backup-and-restore-ceph-files.yml -e backup_dir=/usr/share/ceph-ansible/backup-ceph-files -e mode=backup -e target_node=mon01
|
