What's new

Acronis Cyber Cloud

Added support for new web hosting control panels

Enables lower pricing for partners, by detecting the web hosting control panels of the following brands:

  • DirectAdmin
  • Virtualmin
  • ISPmanager

If a physical server or a virtual machine has one of the web hosting tools listed above, web hosting server quota will be consumed.

Executive Summary Report

  • The Executive Summary Report allows partners to show the business and technical value delivered to their end-customers, thus providing the partners with an opportunity to grow and to reduce the end-customer churn.
  • By default, the report shows the key performance metrics of the following services for the last 30 days or calendar month:
    • Backup
    • Disaster Recovery
    • Antimalware Protection
    • Vulnerability assessment and patch management
    • Data Loss Prevention
    • Cyber Files
    • Cyber Notary
  • Partner administrators can:
    • Preview the report for each customer
    • Customize the content of the report
    • Set up automatic sending of the report in XLS or PDF format by schedule or on-demand
    • Download the report on demand in XLS or PDF format
  • The Executive Summary report will be available on the partner and customer levels in the Acronis management portal.

Support Physical Data Shipping for local backup with replication to cloud

  • Physical Data Shipping for local backup with replication to the cloud:
    • Allows simplifying the delivery of initial backups into the cloud for backup plans with replications.
    • Can be used for locations where the "Always Incremental" scheme of the backup is supported.

Acronis Cyber Protect Cloud

Privacy warnings for Microsoft 365 and Google Workspace backups

  • With privacy warnings, accidental access to the end-customer’s data can be prevented by warning the partner administrator before sensitive data is accessed.
  • Partner administrator will receive a warning about a potential privacy violation when accessing the end-customer's data such as:
    • Viewing mail content
    • Downloading an attachment
    • Sending mail as email
    • Recovering to another Microsoft 365 or Google Workspace organization

Audit log for Microsoft 365 and Google Workspace backups

  • Supports audit logging as a process, as required by internal regulations, and which requires partner administrators to regularly review events, and to search for deviations that have to be investigated further.
  • Partner administrator can regularly, or in the event of incidents, review the events related to Microsoft 365 or Google Workspace cloud-to-cloud backups and find out which user performed a specific action such as data recovery or viewing mail content.

Device Control for macOS

  • With Device Control for macOS, the partners can reduce the risk of insider data breaches on Mac workloads.
  • As part of the DLP component, Device Control neutralizes the primary data loss vector through preventing uncontrolled user access to peripheral devices and local interfaces on protected computers running macOS Catalina and Big Sur.
  • Partners are able to selectively control full or read-only access to removable storage with plain or FileVault-encrypted data, optical drives, USB and FireWire ports, as well as allow or prohibit full access to Bluetooth devices.
  • With allowlisting, partners are able to grant access to certain device classes and individual USB devices, regardless of other access settings
  • Ability to notify users and partner administrators on blocked operations for real-time awareness.

Brand-neutral Cyber Protect installer

With the brand-neutral Cyber Protect installer, Acronis allows partners to provide a fully brand-neutral solution for their end-customers:

  • Ability to manage Acronis or brand-neutral branding per partner
  • Fully brand-neutral installer and tray application
  • Supports Windows, Linux, and macOS
