October’s 26.10 release was a substantial one, and the name on the box changed with it. This bulletin covers the rebrand from Acronis Cyber Protect Cloud to Acronis Cyber Platform, the early-access Cyber Console and its MCP server, GenAI Protection moving into the Security and RMM package, HPE StoreOnce Catalyst support, Microsoft 365 orphaned archive management, macOS 27 support alongside the end of macOS 10.13 to 12, single-node Cyber Frame Local, and the fixes and known issues in 26.10.

Check your macOS agents before anything else

From 26.09, the Acronis Cyber Protection Agent no longer supports macOS 10.13 through 12. Those endpoints need to move to macOS 13 or later.

This is the only item this month with a group of machines that may already be unprotected, which is why it goes first. Run the inventory, find the Macs still on Monterey or older, and plan the OS upgrade — or accept and document that they are out of scope.

At the other end, 26.10 adds macOS 27 support for full-machine backup and recovery, endpoint security, device monitoring and RMM, extending the existing macOS 26 functionality. The current agent build across Windows, macOS and Linux is 26.10.43461.

Acronis Cyber Protect Cloud is now Acronis Cyber Platform

Announced on 14 October 2026, Acronis has aligned its service-provider and corporate customer offerings under a single platform name. Both Acronis Cyber Protect Cloud and Acronis Cyber Protect are now Acronis Cyber Platform.

This is a product and brand naming change, not a replacement backup product. Multi-tenancy, consumption-based licensing and the cyber protection services all continue unchanged underneath. The practical impact lands on your own documentation, quotes and customer-facing material rather than on anything running in production.

GenAI Protection is now included — and it covers Claude

Two changes arrived together here, and the licensing one is the bigger deal.

It is in the bundle now. GenAI Protection is included in the solution-based Security and RMM package as well as Ultimate Protection. It remains available separately under the service-based model.

It now covers Anthropic Claude, joining ChatGPT, Google Gemini, Microsoft Copilot, Perplexity and Grok. Coverage extends to sensitive information entered into prompts, files uploaded to AI assistants, harmful instructions and sensitive-data exposure, Claude web access and supported browser extensions, and the Claude Windows desktop applications — including Claude Cowork, Claude Code, Claude in Excel and Claude in PowerPoint. Prompts and files sent through public or private APIs are covered too.

One limitation to know before you promise it to anyone: Claude support is available only in Full Protection mode.

HPE StoreOnce Catalyst as a backup target

Acronis now supports HPE StoreOnce appliances as backup storage through the native StoreOnce Catalyst protocol. The protection agent communicates directly with the Catalyst store and deduplicates at source before transfer, which cuts both network bandwidth and storage consumption.

Licensing is Backup and Disaster Recovery or Ultimate Protection on the solution-based model, and Standard Protection on the service-based model.

For an MSP this is a commercial opening as much as a technical one: customers with StoreOnce already on the floor can be offered a backup service that uses the hardware they have already bought, rather than Acronis-hosted cloud storage.

Microsoft 365: find the archives nobody is watching

26.10 adds management for orphaned Microsoft 365 backup archives — archives no longer associated with an active backup plan or registered workload, but still consuming storage and still being billed.

You can now identify them, filter them in cloud backup storage locations, include or exclude them in cloud cleanup plans, delete entire backup locations or selected archives, manage encrypted archives using multiple encryption passwords, and apply retention-based cleanup policies.

Worth running across your largest tenants once, as a storage-cost exercise if nothing else.

Cyber Console and the MCP server, in early access

October brought early access to Cyber Console, an AI-native interface that consolidates Acronis management operations into one place. Client Management (customer onboarding and management), Service Desk (alert enrichment and ticket triage), Cyber Compliance (CIS Controls compliance assessment) and Cyber Intelligence (dynamic business reports) are all in early access, with Cyber Studio for workflow and agent development announced as coming soon.

Acronis also introduced an MCP server for Cyber Console, enabling secure integration with external generative AI models and agents — AI-assisted operational workflows, automated incident investigation, customer management assistance and integration with external AI-based IT operations tooling.

Temper expectations on timing. The rollout is gradual, Cyber Console does not yet replace every capability in the existing Management Portal and Protection Console, and availability differs by region and partner.

Cyber Frame Local now runs on one node

Production Cyber Frame Local deployments previously required a cluster of at least three nodes. Version 26.10 introduces a single-node option on one physical server, supporting roughly 5 to 12 virtual machines with no clustered storage requirement, managed centrally through Acronis Cyber Platform, with off-site backup to Acronis Cloud and recovery to Cyber Frame Cloud if the local node fails. The minimum configuration is 8 CPU cores and 32 GB of RAM.

DR Lite is the interesting part: you can recover workloads to Cyber Frame Cloud without a separate Disaster Recovery licence, paying only while the recovered VMs are running. It does not include automated failover or guaranteed cloud capacity, so treat it as a budget option for smaller sites rather than a replacement for a real DR tier.

A new onboarding wizard walks administrators through node selection, network configuration, storage tiers and policies, redundancy and compute, and can be skipped in favour of manual configuration. Cyber Frame Cloud default storage policy names now display their performance level — NVMe 10 IOPS per GB — which makes VM disk sizing easier to reason about.

Fixed in 26.10

• Windows backup — duplicate folder paths with different letter casing caused agent crashes.
• BitLocker — unencrypted volumes generated BitLocker access warnings.
• Linux backup — ext4 volumes larger than 16 TB incorrectly reported filesystem corruption.
• Microsoft 365 — SharePoint agent crashes during folder deletion or temporary unavailability.
• Microsoft 365 — SharePoint and Teams backup failures following network interruptions.
• Exchange Online — mailbox backup warnings involving invalid MAPI types.
• SQL Server — application-aware backup failed after machine credentials changed.
• VMware — VMs with incomplete replication metadata disappeared from device lists.

The BitLocker fix is worth calling out on its own, because those warnings have been appearing on unencrypted volumes for long enough that administrators have learned to ignore them. They should mean something again now.

Known issues to plan around

• Backup validation — validation status may be incorrect or missing for large backup sets. Verify validation results independently.
• Network storage — backup names containing special characters may become inaccessible. Avoid special characters in backup names.
• Windows System State — backup may fail because files are in use. Investigate conflicting processes.
• Acronis Secure Zone — existing backups may appear missing in File Explorer. Verify through Acronis management tools.
• WinPE media — browsing backup files may fail when cloud storage contains corrupted archives. Check archive integrity.
• macOS agent — macOS 10.13 to 12 no longer supported from 26.09. Upgrade macOS to 13 or later.
• Azure agentless backup — storage quota alerts may not appear. Monitor storage consumption independently.
• Disaster recovery — automated failover may fail if the tenant is disabled during the operation. Avoid tenant changes during failover.

Security housekeeping for 26.10

Acronis includes security fixes in the release. Alongside applying them: review the October security advisory, verify deployed agent versions, update Windows, Linux and macOS agents according to compatibility requirements, review MFA and administrator access policies, verify immutable backup configuration, and test recovery from protected backup copies.
