Version 1.8.0

Plesk product version compatibility

This update is available for Plesk versions 17.8.11 Update 35 and newer.

What's new

Early Access program

We have introduced the Early Access update channel to enable our users to test new features and validate compatibility with their setups before rolling out the updates to the entire fleet.

Details of the Early Access Program are provided in this Knowledge Base article https://kb.acronis.com/content/72472.

Users who wish to continue using the mainstream update channel do not have to make any changes to their systems. The update will be available in the mainstream channel approximately four weeks after it is released in the Early Access channel.

Individual protection plans

The extension now defaults to automatically creating an individual protection plan for each Plesk server. This is designed to provide an additional layer of security in the integration while keeping the user experience smooth.

Individual protection plans are associated with the particular workload that initiated the protection plan creation and cannot be revoked or assigned to other workloads.

If you want to protect multiple servers with a single plan, you can create a regular protection plan in the Cyber Protection console and assign these workloads to it. However, any modifications to a protection plan that is shared by multiple workloads can only be made in the Cyber Protection console and not within the extension.

Obligatory extension registration upon installation

To provide an additional layer of security, the extension has been reworked to require obligatory authentication with the Cyber Protection service using user login or API client during extension installation and configuration, regardless of whether the protection agent has already been registered.

Decreased account privileges for registering and configuring the extension

We have decreased the minimum privilege level required to install and configure the plugin to the 'protection user' role.

Dynamic default protection plan naming

To make it easier to identify and distinguish protection plans associated with specific Plesk 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 'Plesk %HOSTNAME%' instead of the generic 'webcp'.

Disabled Google Analytics

The functionality of sending events and usage statistics to Google Analytics was disabled.

Fixed issues

• [CI-21228] Database users not restored upon database recovery
• [CI-21303] Domain recovery fails for sites without PhysicalHosting
• [CI-21534] Authentication via an API Client fails if the protection agent was installed prior to the extension
• [CI-21584] Backup fails with error "The pre-data capture command completed with non-zero return code: 1"
• [CI-22540] Option to authenticate via the extension UI inside a Virtuozzo container was mistakenly removed
• [CI-23002] Time for scheduled and executed backups in UTC instead of the server timezone
• [CI-23232] Recovery Operations Log tab cannot be opened in Plesk v 18.0.51 Update 1 due to a PHP error

Security fixes

Version 1.7.0

Plesk product version compatibility

This update is available for Plesk versions 17.8.11 Update 35 and newer.

What's new

Recovery self-service for Resellers

Users with the Reseller role can browse, export and restore their customers’ data: accounts, databases, websites, mailboxes, etc. Plesk administrators can enable such permission for them by selecting the corresponding setting in the Reseller's service plan. In addition, the administrator can limit the amount of recovery points, exposed to the resellers to provision for different service levels.

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 uses the --no-purge key to call the protection agent uninstaller. This is done 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 extension. Now the value, specified in /usr/lib/Acronis/system_libs/config will be overwritten with the value from the /usr/local/psa/var/modules/acronis-backup/srv/config.ini file.

Improved error messaging

Error messaging was improved to provide more intelligible descriptions for faster troubleshooting.

Fixed issues

• [CI-9061] Database download fails if File Key Management Plugin for MariaDB is used
• [CI-10475] Plesk account recovery fails in case of an invalid Plesk license
• [CI-20576] Website recovery fails for deleted subscriptions

Known issues

• [CI-21600] Deleted mailbox is not available via Roundcube after recovery. As a temporary workaround, please reset the mail account password after the mailbox recovery as per the instruction on the corresponding Plesk help page.

Version 1.6.1

Plesk product version compatibility

This update is available for Plesk versions 17.8.11 Update 35 and newer.

Fixed issues

• [CI-21098] Backup fails with error "Creating of metadata was failed: Site without PhysicalHosting cannot be Webspace" if the Plesk instance has Service Plans without hosting.

Version 1.6.0

Plesk product version compatibility

This update is available only for Plesk versions 17.8.11 Update 35 and newer.

What's new

Service level management for recovery self-service

On the Service Plan configuration page (Resources tab), there is a setting to limit the number of days in the past, for which recovery points will be shown to customers with this service plan. In order to apply this setting, the Permissions tab of the Service Plan configuration page must have the Acronis Backup option selected.

Ability to restore mailboxes without removing newer emails

The mailbox recovery functionality now offers a choice to preserve or delete emails sent or received after creating the backup.

Website view for recovery points browsing

The backup archive content was grouped to allow users to browse, download and restore all files and directories that belong to a particular domain or subdomain. Databases are not recovered as part of website recovery and need to be restored separately through the Databases view.

Other changes and improvements

• [CI-10876] Self-descriptive error message in case a resource cannot be restored because a Service Plan quota has been reached
• [CI-19529] Short cut to the Acronis extension in the customer interface was moved under the Security section in Plesk version 18.0.19 and newer

Version 1.5.9

What's new

The following requirements should be complied with:

• Update both the protection agent and the Plesk 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.

Detailed instructions are provided in the corresponding Knowledge Base article.
