Build619August 28, 2023

Version 1.8.0

What's new

Individual protection plans

To provide an additional layer of security within the integration, each server will now have an individual protection plan created automatically. These protection plans will be specifically associated with the workloads that initiated their creation during integration configuration and cannot be revoked or assigned to other workloads.

If you need to protect multiple servers with a single plan, you can create a protection plan in the Cyber Protection console and assign the respective workloads from there. Note that protection plans shared by multiple workloads can only be edited through the Cyber Protection console and respective API calls, but not within the integration using the script.

The introduction of individual protection plans would not require changes to current setups.

New low-privileged role

To ensure secure and limited communication between integrations and the backup service, a new, low-privileged role is introduced. This role will be tied to specific integration instances and will have restricted access — allowing each integration to handle only its own archives and protection plans. Upon updating with this security release, existing tokens will be seamlessly replaced with new ones, ensuring a smooth transition with no impact on the user experience.

Obligatory plugin registration upon installation

To further enhance security, the integrations are reworked to require mandatory authentication with Acronis Cyber Protect Cloud during the configuration process. This authentication will be necessary regardless of whether the protection agent has already been registered.

Decreased account privileges for plugin registration and configuration

The changes described above allowed us to decrease the minimum privilege level required to install and configure these hosting control panel integrations. Now the 'protection user' role is sufficient for such tasks.

Dynamic default protection plan naming

To make it easier to identify and distinguish protection plans associated with specific cPanel servers in the Cyber Protection console, we have updated the default protection plan naming convention. The default protection plan name will now be dynamically generated as 'cPanel %HOSTNAME%' instead of the generic 'webcp'.

Message about future releases

Starting with the release of version 1.8.0 in May 2023, we are launching an Early Access program. This program will allow users to try out new features and ensure compatibility with their systems before the updates are rolled out to the entire fleet.

To participate in the Early Access program, you will need to switch the plugin repository on your servers. The exact implementation details will be communicated as we release version 1.8.0.

Users who wish to continue using the acronis-cpanel-stable repository don't have to make any changes to their systems. The update will be available in the stable repository approximately 4 weeks after it is released in the Early Access repository.

Build506February 28, 2023

Version 1.7.0

What's new

  • Support of Rocky Linux 8 and Ubuntu 20.04 TLS

    Now the plugin is compatible with two more flavors of the Linux operating system: Ubuntu 20.04 LTS and Rocky Linux 8.

  • New mechanism of running MySQL instances

    Upon database or account recovery operation, the MySQL daemon runs from within the backup archive rather than on the live system. This change solves multiple issues related to database recovery in Virtuozzo Hybrid Server 7.5 containers. It also removes the hard requirement for MySQL version match in the archive and on the target system, thus making it possible to smoothly recover a database after MySQL server system update.

  • Improved MySQL 8 support

    The logic of processing system databases was reworked to cover a wide range of non-typical database configurations available with MySQL 8 and third-party extensions. All non-customer databases are processed as system ones now.

  • Safe extension uninstallation

    Upon uninstallation, the extension calls the protection agent uninstaller with the --no-purge key defined in order to keep the association between the server, its protection plan and backup chain upon re-installation.

  • Unified temporary directory

    The location of the temporary directory was unified across the protection agent and the plugin. Now the value specified in /usr/lib/Acronis/system_libs/config will be overwritten with the value from the /usr/local/cpanel/base/3rdparty/acronisbackup/srv/config.ini file.

  • Database user recovery upon database recovery

    The database recovery procedure was supplemented with an option to recover database users together with the database content.

Fixed issues

  • [CI-10826] File recovery fails because of rsync warning with code 24
  • [CI-19138] Successive recovery and download operations cause the /tmp directory to overflow
  • [CI-19367] Mount points cannot be unmounted in some scenarios when the cPanel account has jailed shell enabled
  • [CI-20379] cPanel accounts recovery fails on decoding the output of cPanel utilities
  • [CI-21488] Metadata collection ignores all accounts, but "localhost" ones
  • [CI-21944] Misleading messages in the data capture log

Known issues

  • WHM Reseller without an associated domain cannot open backup
  • WHM Reseller is unable to restore files that do not exist in the destination folder
  • Recovered database users have missing privileges
  • Service restart does not update the value of ACRONIS_MOUNT_DIR in the protection agent config file
  • Database recovery task stucks in state 'In queue' if recovery has been started before the backup got mounted
Build473January 23, 2023

Version 1.6.12

What's new

  • Protective mechanism in the self-service recovery function that ensures exposure of at least as many recovery points as the number of backup days specified in the plan’s service level.

Fixed issues

  • [CI-21486] cPanel plugin generates excessive load on protection plan management API
  • [CI-20259] Account recovery fails with error "Insufficient disk space is available" although there's enough space in the temporary directory

  • Prompt to keep or delete newer emails upon mailbox recovery was removed for mdbox mailboxes as the functionality is available for maildir mailboxes only

Fixed issues

  • [CI-19605] Canceling a backup task in the cloud console produces error messages in the plugin dashboard
  • [CI-19606] "Account is disabled" error message pops up after the entire server recovery
Build434July 19, 2022

Version 1.6.10

What's new

  • Mailbox recovery can now preserve emails generated after backup creation.
  • cPanel account recovery time was improved by means of optimized cPanel metadata processing.
  • Recovery task handling was reworked to include the archive mounting step into the recovery task and report its status accordingly.
  • Compatibility with the security improvements, introduced in Acronis Cyber Protect Cloud Update 22.07.

    The following requirements should be met:

    • Update both the protection agent and the cPanel & WHM extension to their latest versions

    • Re-authenticate to Acronis Cyber Protect Cloud in order to generate an internal service user for protection plan management via the extension.

    Operations, related to protection plan management via the extension, including protection plan configuration and revocation as well as manual backup start, will be prohibited until then.
