1 Installation It is highly recommended to use the recent Acronis Cyber Backup 12.5 update, as it may include the important security fixes and improvements. If you install Acronis Management Server in the Windows environment, it is recommended to install it on any virtual machine or hardware node except the Domain Controller. It is not recommended to change the accounts under which the services run (https://www.acronis.com/support/documentation/AcronisCyberBackup_12.5/index.html#40078.ht ml).
2 Operations 2.1 Backup security It is recommended to encrypt your backups. As a result, a backup will be stored encrypted at rest and a user will have to enter the encryption password in order to restore or view the saved encrypted backup. For more details how to encrypt backups, refer to the Acronis Cyber Backup 12.5 web help (https://www.acronis.com/support/documentation/AcronisCyberBackup_12.5/#37608.html). 2.
