With this update release, the Acronis flagship cloud product offers enhancements and addresses issues found in previous releases.

What's new

Acronis Cyber Protect Cloud

Ability to set paths for reverted files and folders separately for Windows and macOS within the same protection plan

Administrators who want to protect both Windows and macOS workloads with a single plan can now specify a "Restore folder" path for both Windows and macOS separately (as part of the Network folder protection functionality).

File Sync & Share: share link management for Notarization and eSignature

  • Allows managing links for eSigned documents and files: view, edit, and revoke.
  • Allows viewing the history link shares, link type, revision, and expiration.

Management Portal and Platform Core

Sections management in Executive summary report

The Executive summary report allows partners to show the business and technical value delivered to their end-customers, thus providing partners with an opportunity to grow and to reduce the end-customer churn.

Sections management allows fine-tuning the report view for individual MSP needs:

  • Add, Edit, and Delete sections
  • Change the order of sections in the report
  • Add a widget to a certain section
  • Move widgets inside a section or from one section to another

New branding color schemes

Two new color schemes (pink and magenta) are available in the Branding settings of Management Portal.

ConnectWise Manage PSA integration

Support for offering items with "included features"

Advanced licensing introduced "included features" offering items in Acronis Cyber Cloud 21.03. These new offering items depend on regular offering items and cannot be enabled or disabled separately, but their usage is reported separately. Now, a partner can optionally map "included features" offering items to products in the interface of the ConnectWise Manage integration solution. This feature will become available in other PSA integrations as soon as the pay-as-you-go billing and the product mapping are supported.

This section describes issues that are currently known and provides solutions to avoid the issues where possible.

Acronis Cyber Protect Cloud


  • [ABR-240431] It is possible to apply an existing protection plan with the "Cloud" backup destination, even if the cloud storage quota was exceeded for a tenant. The plan will fail upon execution.

  • [ABR-184900] Local backup usage is not reported for backups stored on a network share with enabled deduplication.
  • [ABR-183764] Local backup usage is not updated for all virtual machine backups after deleting and re-adding a network location.
