@julien-f 0k, is there a specific rule on the format of this identifier?
When I create a backup, I set an email address for reporting but that address or notification setting) is not present in the JSON, why and how can I set it ?
For rolling snapshots, the content is 0k (same identifier in both settings and schedule):
{
  "name": "rolling snapshots",
  "mode": "full",
  "schedules": {
    "gbkk1mbemhg": {
      "cron": "15 12 * * *",
      "enabled": true,
      "name": "daily rolling snapshots",
      "timezone": "Europe/Rome"
    }
  },
  "settings": {
    "": {
      "concurrency": 2,
      "nRetriesVmBackupFailures": 3,
      "timeout": 7200000,
      "offlineSnapshot": false,
      "checkpointSnapshot": true
    },
    "gbkk1mbemhg": {

    }
  },
