Delete Subcloud Backup Data Using DCManager CLI

Subcloud backup data stored centrally or locally can be removed using dcmanager command line interface (). Backup data removal from the local storage requires the subcloud to be managed and online. This restriction does not apply to data removal from central storage.

When a subcloud is deleted, its backup data in central storage is automatically removed.

The command dcmanager subcloud-backup delete can be used to delete backup data for a subcloud or a group of subclouds. By default, the command removes the subcloud backup data on the central systemController. The command accepts the following parameters/options:

release

Mandatory parameter specifying the which release's backup to remove

--local-only

Remove backup data for the specified release on the subcloud

--subcloud <subcloud-name>

The subcloud whose backup data should be removed

--group <subcloud-group-name>

The group of subclouds whose backup data should be removed

--sysadmin-password <sysadmin_password>

Only required if using --local-only option. If not specified when using --local-only option, user will be prompted for the password. Recommend that this option is ONLY used for automation; i.e., for interactive use, do not use option and specify password on prompting, so as to avoid sysadmin password getting into log files.

The release version and --subcloud/--group are mandatory parameters.

This operation has one caveat. After this command is carried out successfully, both backup_status and backup_datetime fields will be set to 'unknown' and 'None' respectively even though there might be another set of backup data in either central storage or local storage.

Delete backup data for a single subcloud

• The System Controller is healthy and ready to accept dcmanager related commands.
• The release version is valid.
• The subcloud is managed and online (applicable to backup data removal from local storage only).

To delete backup data for from central storage:

~(keystone_admin)]$ dcmanager subcloud-backup delete 22.12 --subcloud <subcloud>

To delete backup data for from local storage:

~(keystone_admin)]$ dcmanager subcloud-backup delete 22.12 --local-only --subcloud <subcloud> --sysadmin-password <sysadmin_password>

Delete backup data for a group of subclouds

The above subcloud-backup delete operations can be performed for a group of subclouds simultaneously by replacing --subcloud option with --group option. For instance, to delete backup data for for a group of subclouds from central storage:

~(keystone_admin)]$ dcmanager subcloud-backup delete 22.12 -group <group>
