Generally, cloud job sessions are marked failed on the SP backup server in the following cases:
- All cloud gateways are unavailable
- There is not enough space on the disk
- An existing connection was forcibly closed by the remote host
- Repository quota exceeded
All issues above should be corrected by a SP, and therefore Veeam reports such jobs as failed. For other types of issues, a failed job may be marked successful because it cannot be fixed on the SP side and requires involving a tenant.
NOTE: Direct Agent to Cloud job sessions are always marked as successful in the SP's console.
