AZ备份策略retentionDuration保存时间不超过7天

Question

我正在使用AZ CLI配置到我的MVs的备份。

我创建了以下备份策略：

{
  "eTag": null,
  "id": "/#############",
  "location": null,
  "name": "DefaultPolicy",
  "properties": {
    "backupManagementType": "AzureIaasVM",
    "instantRpDetails": {
      "azureBackupRgNamePrefix": null,
      "azureBackupRgNameSuffix": null
    },
    "instantRpRetentionRangeInDays": 2,
    "protectedItemsCount": 1,
    "retentionPolicy": {
      "dailySchedule": {
        "retentionDuration": {
          "count": 30,
          "durationType": "Days"
        },
        "retentionTimes": [
          "2021-07-30T18:30:00+00:00"
        ]
      },
      "monthlySchedule": null,
      "retentionPolicyType": "LongTermRetentionPolicy",
      "weeklySchedule": null,
      "yearlySchedule": null
    },
    "schedulePolicy": {
      "schedulePolicyType": "SimpleSchedulePolicy",
      "scheduleRunDays": null,
      "scheduleRunFrequency": "Daily",
      "scheduleRunTimes": [
        "2021-07-30T18:30:00+00:00"
      ],
      "scheduleWeeklyFrequency": 0
    },
    "timeZone": "UTC"
  },
  "resourceGroup": "RSGNAME",
  "tags": null,
  "type": "Microsoft.RecoveryServices/vaults/backupPolicies"
}

但是，当我检查当前可用的备份时，只能看到接下来的7天。

$ az backup job list --resource-group $MYGROUP --vault-name $MYVAULT --output table

问题出在哪里？如您所见，该策略已在30天内完成设置

如注释中所述，请指定--start-date和--end-date参数以获取这些日期之间的备份列表。
