How To Install the Acronis BackUp Plugin on cPanel

by | May 11, 2021

How To Install the Acronis BackUp Plugin on cPanel? We can help you.

With the Acronis Backup Plugin, we can back up an entire cPanel server to the cloud storage with the disk-level backup.

Among its many other features, we can recover the entire server including all of the websites.

As part of our Server Management Services, we assist our customers with several Acronis queries.

Today, let us see how to install and use the Acronis Backup plugin for WHM and cPanel.


How To Install the Acronis BackUp Plugin

In order to begin, our Support Techs suggest having:

  • PHP version 5.6 or later.
  • Granular recovery of databases is supported only for local MySQL and not of PostgreSQL databases.
  • Besides the plugin, we need a backup agent on the same machine.

With the Acronis Backup Plugin, we can start a backup on demand, configure the backup schedule and, perform the recovery from the WHM and cPanel interfaces.

To install the Acronis Backup plugin for WHM and cPanel, we run:

sh <(curl -L || wget -O –

Install the backup agent

Initially, we register a beta account via

Then we create a New Customer group under the Partner account previously created.

Once done, we need to set up the backup agent:

  • Log into WHM
  • Then click Plugins > AcronisBackup
  • Here, we specify the credentials of the account to which the machine assigns. Specify the credentials of an account created within the customer group and not partner administrator credentials.
  • Follow the on-screen prompts.
  • During the installation, the software checks if the ports for communication with the cloud are open. If any are closed, it shows the hostnames and ports the software needs to access.
  • Open ports if necessary and close the wizard and restart the installation.

To back up the Virtuozzo container, we must install the backup agent on its host.

Uninstall the plugin

To uninstall the Acronis Backup plugin for WHM and cPanel, we run:

$ yum remove acronis-backup-cpanel

Removing will uninstall the backup agent from the cPanel server. The backup accounts we create and the backup data will be intact.

To enable self-service recovery for cPanel users, we must enable Acronis Backup for them in Feature Manager.


Common error

Recently, while a customer was accessing the plugin from WHM, it threw an error to check the log file.

Now when he click on the Acronis icon in WHM, a greyish screen with a white box at the top with 3 blue lines appears.

Since there is nothing to click, he tried to remove the plugin using the yum remove command. This leads to:

error: %preun(acronis-backup-cpanel-1.0-223.el7.centos.x86_64) scriptlet failed, exit status 1
Error in PREUN scriptlet in rpm package acronis-backup-cpanel-1.0-223.el7.centos.x86_64
Verifying : acronis-backup-cpanel-1.0-223.el7.centos.x86_64 1/1

Here, yum fails because a script that should be executed in the %preun section does not exist.

In order to solve this, our Support Techs suggest the following methods.

To remove the plugin, we execute:

rpm -e –noscripts acronis-backup-cpanel

Instead of,

yum remove acronis-backup-cpanel

Here, the –noscripts says rpm to avoid executing %preun and %postun scripts.

This will resolve the issue with the plugin removal.

To reinstall the plugin without reinstalling the Backup Agent, we execute:

yum reinstall acronis-backup-cpanel

If it does not help, we perform the following:

  1. Initially, we export UNINSTALL_BACKUP_AGENT=0
  2. yum remove acronis-backup-cpanel
  3. Then run “ps aux | grep acronis_backup_srv” and kill all found processes.
  4. yum install acronis-backup-cpanel
