Features and API fields approaching or past end of support.

Clumio publishes deprecations separately from the changelog. Dates below are from the Clumio deprecations page.

Item	Announced	End of support	Status
Microsoft 365 backup	26 May 2026	1 September 2026	Ended
Legacy TLS 1.2 RSA and non-GCM ciphers	19 June 2026	14 July 2026	Ended
Legacy type values in S3 Backtrack	24 October 2025	30 November 2025	Ended
Bucket-level S3 continuous backup	12 September 2025	15 October 2025	Ended
Malware naming in the S3 Threat Scan API	14 August 2026	14 July 2027	Dual-run

Microsoft 365 backup

Clumio’s Microsoft 365 backup solution is no longer supported.

Legacy TLS 1.2

API endpoints require TLS 1.3, or TLS 1.2 with Forward Secrecy (ECDHE-AES-GCM) cipher suites. Clients, proxies, and load balancers that still use RSA key exchange or non-GCM suites will fail handshake. See Authentication.

Legacy type values in S3 Backtrack

The S3 Backtrack restore and preview APIs no longer accept the legacy type values. Requests using them return validation errors.

Deprecated	Use instead
Rollback	rollback
Undo delete marker	undo_delete_marker

The default when type is omitted is rollback.

Bucket-level S3 continuous backup

S3 continuous backup is configured through backup policies. Bucket-level enablement is not supported in the UI, the API, or the Terraform provider. Existing bucket-level configurations were upgraded to policy-driven continuous backup.

These API surfaces no longer operate as they did:

• PATCH /datasources/aws/s3-buckets/{bucket_id}
• The event_bridge_enabled field on S3 bucket GET responses

S3 Threat Scan API

The S3 Threat Scan API now uses threat naming. Malware-named fields and endpoints still return the same values until 14 July 2027. During the dual-run, both names are present so clients can switch at any time.

Surface	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 report export	export-protection-group-s3-asset-malware-report with malware_scan_task	export-protection-group-s3-asset-threat-report with threat_scan_task

If both threat_scan and malware_scan are sent on policy create or update, threat_scan takes precedence.
