Example 2: Implement 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.
• Binding 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": {
                 "id": "7954175b-ef2c-432c-b936-f6c83df7a593",
                 "name": "default",
                 "type": "time",
                 "properties": {
                     "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 "Binding 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"
         }
     }
