Hey @Pandora,
You can use the aci_config_snapshot module that ansible provides. you can create new snapshots using configExportP class and remove snapshots using configSnapshot class. Something like this:
- name: Create a Snapshot
  aci_config_snapshot:
    host: apic
    username: admin
    password: SomeSecretPassword
    state: present
    export_policy: config_backup
    max_count: 10
    description: Backups taken before new configs are applied.
  delegate_to: localhost
- name: Query all Snapshots
  aci_config_snapshot:
    host: apic
    username: admin
    password: SomeSecretPassword
    state: query
  delegate_to: localhost
  register: query_result
- name: Query Snapshots associated with a particular Export Policy
  aci_config_snapshot:
    host: apic
    username: admin
    password: SomeSecretPassword
    export_policy: config_backup
    state: query
  delegate_to: localhost
  register: query_result
- name: Delete a Snapshot
  aci_config_snapshot:
    host: apic
    username: admin
    password: SomeSecretPassword
    export_policy: config_backup
    snapshot: run-2017-08-24T17-20-05
    state: absent
  delegate_to: localhost
