What's new

Acronis Cyber Protect Cloud

Off-host data processing for backup management operations

Reduce the CPU and RAM consumption on the protected workload by offloading backup management operations to a dedicated workload. This allows running such operations independently from the protection plan, and on a separate schedule.
The following operations can be offloaded:

  • Backup replication
  • Validation
  • Retention
  • Conversion to a virtual machine

Conversion of backups to Scale Computing HC3 virtual machines

Achieve near-zero RTO for your most important workloads by regularly converting the backups into ready-to-use Scale Computing HC3 virtual machines.
The conversion can be performed independently from a protection plan, on a separate schedule, or by a separate agent.

Disaster Recovery: LVM support for disk backups with agents and linear LVM volume

Protect Linux physical and virtual machines that have logical volumes (LVM).

VMware Cloud Director protection improvements

More protection options are now available in the VMware Cloud Director tenant portal, allowing better compliance with the backup policies and regulations of the tenant.

Web installer for Cyber Protection agent for Mac

Minimize download times with the lightweight Cyber Protection agent installer for Mac. Works on both Intel and Apple M1 CPUs.

File Sync & Share: drag and drop files and folders for upload in the Web UI

Upload files and folders (including sub-folders) by dragging and dropping them into the File Sync & Share's Web UI.​

Management Portal and Platform Core

SKU in usage report for cloud distributors

Match the metrics in Usage reports to the related prices in the Price list easily, by using the additional SKU-related fields in the report.​

RMM and PSA integrations

More prominent integrations in the ​management portal

Previously, customers would have to dig through Settings, then find the Integrations menu option every time they needed to make a change in integrations settings​.
Now, the Integrations page is just one click away.

Two-way quota sync in ConnectWise Manage​​

Before, when using the pre-paid billing mode, quotas could only be set from the ConnectWise Manage interface. This meant that field engineers would have to wait for administration to update Agreements before they could, for example, deploy protection of a new workload.​
Now, they can update quotas on the Acronis Cyber Cloud side and have that reflected in the Agreement​.
This is also the recommended method for partners who use ConnectWise Manage to move from Legacy editions to the new billing modes.

Auto-create names for services in services mapping ​in Autotask

Before, in product mapping in the Autotask integration, new services had to first be created in Autotask before they could be mapped in Acronis Cyber Cloud​. Now, MSP technicians can create new services from the mapping UI, with names for new services automatically pre-filled.
The new services are automatically created in Autotask when the mapping is saved​.
This works essentially the same as in ConnectWise Manage integration.​

    • Solution: Select a different volume for the mounted VM disks path. The space will be consumed only for changes generated inside the mounted VM and it will not occupy the entire size of the virtual disk.
  • [ABR-137564] Cross-platform recoveries (when the backup was created not by Agent for Hyper-V) into a new Hyper-V virtual machine by Agent for Hyper-V always produces the Gen 1 version of virtual machine.
