Example 2: Implementing Automatic Backup for a Vault

Scenarios

This section describes how to use APIs to set a backup policy and apply the policy to a vault for automatic backup.

Involved APIs

  • Creating a Policy: Define when a backup task runs and how long the backups are retained.
  • Applying a Policy to a Vault: Apply a policy to a vault.

Procedure

  1. Create a backup policy.
    • API

      URI format: POST /v3/{project_id}/policies

      For details, see "Creating a Policy".

    • Sample request

      POST: https://{endpoint}/v3/0605767b5780d5762fc5c0118072a564/policies

      Obtain the value of {endpoint} from "Regions and Endpoints".

      Body:

      {
          "policy": {
              "name": "dh_test_policy",
              "trigger": {
                  "properties": {
                      "pattern": ["FREQ=WEEKLY;BYDAY=SU,MO,TU,WE,TH,FR,SA;BYHOUR=23;BYMINUTE=00"]
      }
              },
              "operation_definition": {
                  "retention_duration_days": 30
      }
          }
      }
    • Sample response
      {
          "policy": {
              "id": "30d7cf2d-14fc-415b-b7da-858b37f47250",
              "name": "dh_test_policy",
              "operation_type": "backup",
              "operation_definition": {
                  "retention_duration_days": 30
              },
              "enabled": true,
              "trigger": {

                      "pattern": [
                          "FREQ=WEEKLY;BYDAY=SU,MO,TU,WE,TH,FR,SA;BYHOUR=23;BYMINUTE=00"
                      ],
                      "start_time": "2020-08-17 08:39:44"
                  }
              },
              "associated_vaults": null
          }
      }
  2. Apply the policy to a vault.
    • API

      POST /v3/{project_id}/vaults/{vault_id}/associatepolicy

      For details, see "Applying a Policy to a Vault".

    • Sample request

      POST: https://{endpoint}/v3/0605767b5780d5762fc5c0118072a564 /vaults/ea7b8717-2543-478a-a92d-3ca7ee448f67/associatepolicy

      Obtain the value of {endpoint} from "Regions and Endpoints".

      Body:

      {
          "policy_id": "30d7cf2d-14fc-415b-b7da-858b37f47250"
      }
    • Sample response
      {
          "associate_policy": {
              "vault_id": "ea7b8717-2543-478a-a92d-3ca7ee448f67",
              "policy_id": "30d7cf2d-14fc-415b-b7da-858b37f47250"
