Microsoft 365 backup
Clumio's Microsoft 365 backup solution is deprecated.
Malware naming in the S3 Threat Scan API
The S3 Threat Scan API now uses threat naming. The malware-named fields and endpoints still work and return the same values, but they are not supported after July 14, 2027. Until then the deprecated fields are returned alongside the new ones with identical values, so you can switch over at any time.
| API | Deprecated | Use instead |
|---|---|---|
| Policy definitions | operations[].advanced_settings.protection_group_backup.malware_scan |
threat_scan |
| Protection group backups | malicious_object_count, malicious_objects_list_link |
threat_object_count, threat_objects_list_link |
| S3 asset threat report export | export-protection-group-s3-asset-malware-report with malware_scan_task |
export-protection-group-s3-asset-threat-report with threat_scan_task |
On policy create and update, if both threat_scan and malware_scan are sent, threat_scan takes precedence.
Legacy TLS 1.2 RSA key exchange and non-GCM cipher suites
Effective July 14, 2026, API endpoints require TLS 1.3, or TLS 1.2 with Forward Secrecy (ECDHE-AES-GCM) cipher suites. Support for legacy TLS 1.2 RSA key exchange and non-GCM cipher suites is removed. Verify that API clients, proxies, load balancers, and other TLS-terminating components meet these requirements.
Legacy type enum values in S3 Backtrack
The type field in the S3 Backtrack restore and preview APIs no longer accepts its legacy values. Requests using them after November 30, 2025 return validation errors.
| Deprecated value | Use instead |
|---|---|
Rollback |
rollback |
Undo delete marker |
undo_delete_marker |
The default when type is omitted changed from Rollback to rollback.
Bucket-level enablement for S3 Continuous backup
S3 Continuous backup is configured through backup policies. Bucket-level configuration is not supported after October 15, 2025, through the UI, the API, or the Terraform provider. Existing bucket-level configurations were upgraded to policy-driven continuous backup, with no loss of functionality or data.
These API surface areas no longer operate as they did:
