Overview

We are happy to introduce Acronis Cyber Protect 15 – an AI-powered integration of Data Protection and Cybersecurity. Acronis Cyber Protect 15 integrates backup, disaster recovery, AI-based malware and ransomware protection, remote desktop, and security tools in a single solution.

One integrated solution:

  • Eliminates complexity
  • Delivers new security capabilities
  • Keeps costs down

What's new in Acronis Cyber Protect 15 Update 4

Always-incremental scheme for Acronis Secure Zone

  • Allows to use the Acronis Secure Zone space more efficiently – no need to have periodic full backups that occupy additional space.

One-click recovery

  • Automates the recovery of workloads by using Acronis Startup Recovery Manager.
  • IT staff no longer need to manually recover workloads that cannot boot.

Secured connection to Active Directory over SSL

  • Communications with Active Directory are performed over SSL by default (LDAPS support).

  • Get full control over licenses distribution between multiple product installations (including isolated environments)
  • Synchronize new and updated licenses automatically with the product
  • Track licenses usage and plan license upgrades, by having a clear overview of the current license utilization
  • Keep licenses safe in Acronis Cyber Protect Cloud, without a chance to the lose license keys due to a local device failure

Convert backup to VM on Scale Computing HC3

  • Migrate your existing physical or virtual workloads into Scale Computing HC3 as standby VMs
  • Keep spare VMs created from backups and regularly updated with the latest incremental changes from the original source machines. These VMs will be always ready to start and take over the original workloads responsibilities in case disaster strikes

Application-aware backup for VMs on Hyper-V

The new application-aware backup of Hyper-V VMs by the Agent for Hyper-V improves the backup and recovery of Microsoft SQL Server, Microsoft Exchange Server, Microsoft SharePoint, and Microsoft Active Directory Domain Services running on Microsoft Hyper-V.

Finalizing the virtual machine running from backup on Hyper-V

While a virtual machine is running from a backup, the virtual disks content is taken directly from its backup. Therefore, the machine will become inaccessible or even corrupted if the connection is lost to the backup location or to the backup agent. You have the option to make this machine permanent, that is, recover all of its virtual disks, along with the changes that occurred while the machine was running, to the datastore that stores these changes. This process is named finalization.

This process is now supported for both ESXi and Hyper-V.

Forensic Backup

Image-based backup with valuable, additional data added to backups

Remote device wipe

Helps you prevent data loss from stolen devices.

Updated Cyber Protection Monitor

Displays real-time antivirus protection status.

Installation notes

Known issues

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

Installation and upgrade

  • [ABR-325252] Agent for Hyper-V cannot be re-registered on the management server via "Devices" → "Add" if it was successfully installed and removed before.

    Solution: restart the Acronis services on the agent before registration attempt.

  • [ABR-312731] Chain upgrade sequence, such as Acronis Cyber Backup 12.5 Update 5 → Acronis Cyber Protect 15 → Acronis Cyber Protect 15 Update 1 fails with "Error 0x430023: It is forbidden to use ''`"&?*$<>;\/#{}' symbols in names." error if the tape pool contains special symbols in its name.
  • [ABR-218875] When Acronis Cyber Protect 15 is uninstalled without using "Remove the logs and configuration settings" option and installed under new user, then new backup plans creation would fail with "Windows error: (0x80070005) Access is denied" error

    Solution: Uninstall Acronis Cyber Protect 15 without using "Remove the logs and configuration settings" option and install specifying the same existing user account which was used for the 1st initial installation.

  • [ABR-217534] When the backup agent is installed using HTTP proxy it still requires that the hostnames of Acronis Cloud servers (for example "baas-fes-us3.acronis.com") are resolved properly from the agent side, even if DNS redirection is set up within the proxy server.
  • [ABR-144289] Deployment of Acronis Cyber Protect Backup Appliance (All-in-One) from OVF template onto ESXi hosts versions 5.1 or lower produces VM with wrong guest OS type: "Other (32-bit)" which causes appliance malfunction.

    Solution: Change the guest OS type of the appliance VM to "Other 3.x or later Linux (64-bit)" via vSphere client.

  • [ABR-143693] Deployment of Acronis Cyber Protect Backup Appliance (All-in-One) from OVF template does not work when using vSphere Web Client on vCenter version 6.5 U1 build 5973321, since this version of vCenter does not support deployment from OVF templates (only OVA format is supported)

    Solution: Prepare the virtual machine for Acronis Backup appliance installation manually as described in documentation and boot it from Acronis Backup appliance ISO to proceed with the installation.

  • [ABR-142841] Acronis Cyber Protect Backup Appliance (All-in-One) ISO cannot boot on EFI systems

    Solution: use BIOS systems.

  • [ABR-142560] Deployment of Acronis Cyber Protect Backup Appliance (All-in-One) from OVF template does not work when using vSphere Host Client on ESXi version 6.5 with error: "A required disk image was missing"

    Solution: Either perform OVF deployment using vSphere Web Client instead of vSphere Host Client OR prepare the virtual machine for Acronis Cyber Protect Backup Appliance (All-in-One) installation manually as described in documentation and boot it from Acronis Cyber Protect Backup Appliance (All-in-One) ISO to proceed with the installation.

  • [ABR-131165] Simultaneous upgrade of multiple Virtual Appliances in the backup console is not possible.

    Solution: update Virtual Appliances one by one.

  • [ABR-130409] A machine may not appear on the Devices tab after Acronis Backup agent installation if the Acronis Backup Management Server host name cannot be resolved to IP from the machine where the agent is installed. The following error message appears in the installation log: "Could not resolve host: [HOSTNAME]; Host not found".

    Solution: When deploying an agent to a machine use the new GUI option to define the management server registration address which will be used by the agent (host name or IP). Alternatively ensure that the management server is accessible by its host name from the machine with the agent.

  • [ABR-130294] Updating or upgrading Agent for VMware (Virtual Appliance) that was encrypted by using vSphere 6.5 encryption fails. The following error appears: "An encrypted virtual disk device requires an encrypted virtual machine."

    Solution: Decrypt the appliance before update or upgrade.

  • [ABR-118182] In some cases, installation may hang at 96% for an period of time up to 10-20 minutes because of the Microsoft.VC90.CRT runtime package installation. The main symptom is the Windows Modules Installer (TiWorker.exe) process constantly consuming CPU resources.

Common

  • [PLTFRM-18969] It is not possible to protect Microsoft SQL on a machine with a workstation operating system, in the case Agent for Hyper-V is also installed among local agents.
  • [ABR-279757] Applying a protection plan to Agent for Windows installed on Windows Server 2008 (32 bit) always fails.
  • [ABR-255521] The number of total runs and successful runs is zero for the Microsoft Office 365 resources.

  • [ABR-128209] After unmounting a volume mounted from a backup in the read/write mode, a new recovery point is added, even if the mounted volume was not modified. The root cause is that Windows automatically discovers newly appeared volumes and applies metadata changes to them, which forces Acronis Backup 12.5 to preserve these changes in a new recovery point during unmounting.
  • [ABR-127363] The cleanup rule By total size of backups is not available in the backup console if the backup destination is Acronis Cloud Storage.
  • [ABR-121236] Exporting multiple plans from the Plans tab does not work.
