Zmanda Cloud Backup creates the amandabackup user during installation. This user is used for backup and restoration, and is critical to the process.

You can create amandabackup in the Windows domain. All future ZCB installations will use this domain user instead of creating a local user.

To convert a amandabackup local user to domain user

On the domain controller:


The amandabackup user is created on the domain by default if a domain is detected. Users can choose to create the user locally instead. If no domain is detected, amandabackup is created locally.

If it is ever necessary to change from a local amandabackup user to a domain amandabackup user, please follow these directions.

Option 1: Allow the installer to create the domain amandabackup user

The installer can take care of amandabackup account creation, even on a domain.

On any machine that is currently running ZCB, do the following:

  1. Uninstall ZCB.
  2. During uninstallation, you will be asked if you wish to preserve configuration details.
  3. Say yes to preserve configuration details.
  4. Re-install ZCB.
  5. During installation you will be asked to create the amandabackup user account.
    1. Be sure to choose the domain option.

If there are additional machines that run ZCB, please repeat steps 1-4 on each machine. On step 5, you will be asked to provide the password for the existing domain amandabackup account.

Option 2: Add the domain amandabackup user manually

Create amandabackup in Active Directory

On the domain controller:

  • Create a new user in Active Directory.
  • Enter amandabackup as the User Logon Name.
  • Create a password for the amandabackup user.
  • Be sure that the user must change password at next logon option is disabled.
  • Be sure that the password never expires option is enabled.
  • Add amandabackup to the following groups:
    • Administrators
    • Backup Operators
    • Domain Users
    • Users

Once the account is created on the domain, we must force ZCB to

Change the Windows Services to use the new domain amandabackup user

Do the following on every system that needs to use the new domain amandabackup user.

  • Open Services.msc
  • Locate ZWC Service.
  • Right-click and choose Properties.
  • Go to the Log On tab.
  • Change the log-on user to use the domain amandabackup user account instead of the local account.
  • Apply the changes and restart the service.
  • Repeat these steps for ZCB Service also.

If the password for the domain amandabackup user is identical to the password for the original local amandabackup user account, no further steps are necessary.

If the password is not the same, do the following.
