Notes

Backup jobs return the ID:

BACKUP TABLE default.test TO Disk('backups', '2.zip')

Query id: 35f1e28b-1d8c-4498-aba3-ff7e59771ad3

┌─id───────────────────────────────────┬─status─────────┐
│ 17a599e3-45d0-45c2-b6b6-f4e4cb8ae8d7 │ BACKUP_CREATED │
└──────────────────────────────────────┴────────────────┘

Daraus folgt: SELECT * FROM system.backups WHERE id = '17a599e3-45d0-45c2-b6b6-f4e4cb8ae8d7';
