What's New in Acronis Cyber Protect Cloud 25.11

Every software update tells its own story. It’s not just a list of patches or a version number change—it’s how the tool evolves to address new risks and real-world security needs. Acronis Cyber Protect Cloud 25.11 arrives with targeted improvements in storage, SaaS backup, EDR/RMM, and Disaster Recovery.

In this article, we’ll walk you through what’s new in version 25.11, why it might be worth the upgrade, and how to make the most of its improvements.

Key Updates in Acronis Cyber Protect Cloud 25.11

Acronis introduced focused changes in this release: enhancing real-world security (EDR/browser) and simplifying operations for IT teams and MSPs. Here’s what stands out most—complete with what it is, what it’s for, and what you should keep in mind.

1) Archival Storage via Seagate

If your challenge is storing data for months or years (compliance, audits, historical records) without paying “premium” prices for data that’s rarely accessed, this will catch your attention.

You can now use economical, S3-compatible archival storage designed for data retention over 6 months. It’s managed via a dedicated SKU and billed per TB using a PAYG (pay-as-you-go) model.

Why it matters

1. Provides a secure, immutable layer with compliance in mind.

2. Reduces maintenance workload when managing large-scale, long-term files.

Points to consider

1. Not meant for daily backups: it doesn’t function as a regular backup destination.

2. Minimum retention is 6 months. Early deletion may incur extra charges.

2) SaaS Backup: File-Level Deduplication for Microsoft 365 and Google Workspace

This is one of the more “business-driven” changes: if you back up Microsoft 365 or Google Workspace, you know there’s a lot of duplicated content (attachments, shared files, duplicate items in Teams/SharePoint).

With deduplication, Acronis removes redundant data within the archive—leading to less storage usage (and typically, lower costs).

Direct benefit

Estimated size reductions of up to:

1. 50% in Teams

2. 40% in SharePoint

3. 30% in user drives

Improves customer experience by optimizing storage without adding complexity.

Points to consider

1. Applies to new data in cloud-to-cloud backups; existing backups remain unchanged.

3) Acronis EDR: Threat Hunting with Event Search (General Availability)

If your focus is on more advanced security (not just “block and move on”), this is a big plus. With Event Search, teams can perform real threat hunting: searching for suspicious activity in EDR telemetry within a time range, using custom queries, and even saving and sharing those queries for repeated investigations.

Why it’s valuable

1. Helps proactively detect IoCs and unusual behaviors.

2. Supports advanced queries using XQL (Acronis XDR Query Language).

4) Acronis EDR: Improved URL Filtering (Clearer Blocking + HTTP/2 and QUIC Support)

URL filtering just got more modern: it now includes a browser protection extension for Chrome and Edge, along with support for HTTP/2 and QUIC—protocols commonly used on today’s websites.

Additionally, when a user tries to access a blocked site (HTTP or HTTPS), they get a clear message, reducing “it’s not loading” tickets with no context.

Key benefits

1. Better user experience (clear block messages).

2. Safer browsing with compatibility for modern web technologies.

5) Acronis RMM: Customizable Baselines for Microsoft 365 Security Posture

This directly addresses a common MSP/IT need: “I want to standardize Microsoft 365 security per client” without reinventing the wheel each time.

You can now create per-client strategies using customizable baseline templates based on business and compliance needs. Best of all, there are 40+ ready-to-use baselines—including Intune for Windows, macOS, Android, and iOS.

What you can do (as an admin)

1. Create, edit, deploy, and revoke baselines per tenant.

2. Add/configure/remove baselines within templates.

3. Change or remove the default template used during onboarding of new tenants.

6) Immutable Storage: Now Only Disabled via Support

If you rely on immutable storage as part of your anti-ransomware strategy, this update adds peace of mind: it can no longer be disabled “by accident” from the console. To turn it off, you must go through support.

What this means for you

1. Increased security and compliance, especially in regulated environments.

2. Reduced risk of human error (accidental click) or malicious tampering if an account is compromised.

7) Disaster Recovery for Proxmox: Agentless Backup and Failover

Acronis now supports Disaster Recovery for virtual machines on Proxmox with agentless backup and failover, plus site-to-site VPN connectivity using an OpenVPN appliance.

What’s most useful in practice

1. You can run test failovers (no impact on production) and real failovers during incidents.

2. Supports automated incremental recovery, reducing time and effort during restoration.

Important consideration

1. DR to Microsoft Azure is not supported in this scenario.

8) Disaster Recovery for RHEL 9.x: Continuity for Modern Linux Environments

If you’re running workloads on Red Hat Enterprise Linux 9.x, they’re now covered by Disaster Recovery too. The platform enables both test and production failover, helping maintain continuity even when things go wrong.

Key benefits

1. Improved business continuity for current Linux environments.

2. Compatible with typical DR scenarios: testing, switching over, and orderly recovery.

Supported scenarios

1. DR for RHEL workloads

2. Test and production failover

Updated Components: New Agent Versions

In this release, Acronis has updated the Acronis Cyber Protection Agent—the “engine” that powers backup, protection, and many core functions on endpoints. The versions are as follows:

1. Windows: v25.11.41312

2. Mac: v25.11.41312

3. Linux: v25.11.41312

Resolved Issues: Highlights from 25.11 (Without Unnecessary Jargon)

In addition to new features, this update also includes a long list of fixes that improve stability, visibility, and daily operations.

Active Protection

1. Fixed a bug where Windows would report that antivirus was off, even though real-time protection was active.

2. Resolved an issue where the Acronis service could freeze after rebooting the protected device.

Agent (Backup, Recovery, and Update Improvements)

1. The console now accurately reflects recovery progress—no more misleading info.

2. Improved VM backup error messages: instead of vague “invalid parameters,” you now get disk/partition-specific errors (much more helpful for troubleshooting).

3. Fixed agent update failures in Windows caused by driver issues—common blockers for mass deployment.

4. On Linux, resolved installation/update issues related to dependencies (e.g., RPM/APT conflicts) and errors like SetStandbyModeFailed.

5. Fixed a bug where quick anti-malware scans could fail with error 502.

Cloud Integrations

1. In cPanel, fixed an interface issue where it falsely showed “no backups yet” even when restore points existed.

General Console and UX Fixes

1. Fixed incorrect icon display for Synology NAS.

2. New backup replication plans now show up correctly in the console.

3. Improved alert consistency: some alerts weren’t syncing properly between the Protection and Alerts tabs.

4. For offline workloads with very outdated agents, the delete button now appears as expected.

5. Fixed a weird behavior where plans could be applied to both users and groups simultaneously—causing errors in retention settings for cloud-to-cloud mailbox backups.

6. Resolved an issue where database backup statuses weren’t updating correctly.

RMM (Monitoring and Remote Access)

1. Software inventory now updates better when outdated apps are removed.

2. Fixed a curious (but annoying) issue: during remote sessions, Cyber Protect Connect could trigger caps lock on the remote machine.

Virtualization Protection (Hyper-V)

1. Resolved a bug in Hyper-V VM backups where virtual disk names containing “&” would cause the backup to fail.

Conclusion

In short, Acronis Cyber Protect Cloud 25.11 is a valuable update for two main reasons: visible improvements (more efficient storage, EDR/RMM enhancements, and new Disaster Recovery options) and the behind-the-scenes fixes that often have the biggest day-to-day impact—resolving bugs, stabilizing the agent, and making the console more reliable.
