Last update: 23-03-2021

Starting with version 5, archive names in Acronis Cyber Protect Cloud/Acronis Cyber Backup Service are generated automatically based on machine's hostname and ID. Acronis software caches the hostname in the configuration to prevent new archive creation once the hostname is changed (which might be a common case for Macs that can obtain hostnames by DHCP). You can manually change the setting, if you want to create a new archive with the new hostname.

On a Windows machine, the hostname is stored in HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\BackupAndRecovery\Settings:

  1. Open Windows Registry: Start -> Search -> regedit.exe
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\BackupAndRecovery\Settings:
  3. Double-click CachedMachineName:
  4. Change the hostname:
  5. A new archive is created upon the next backup run. The archive contains the new hostname.

On a Linux machine, the setting is saved in /var/lib/Acronis/BackupAndRecovery.config

On a Mac, the setting is saved in /Library/Application Support/Acronis/Common/BackupAndRecovery.config
