Purpose

This article describes the functionality of the "Update Password" command, available at Preferences > Advanced > Update Password.

This command updates the password for the amandabackup user in ZCB's internal MySQL database and for ZCB's background services.

What's going on?

Due to security restrictions in certain Windows environments, domain group policies mandate that user account passwords change regularly. In fact, the "Default Domain Policy" of a new Windows AD forest has the "Password Expiration" policy set to 42 days.

In most Active Directory configurations, the Administrator will configure the "Password Never Expire" property for service-related user accounts, such as ZCB's amandabackup user.

It is recommended to enable the "Password Never Expire" property for the amandabackup user, unless your organization's security policy requires the password to be changed.

If the password policy demands that the amandabackup user password on the system must be changed, ZCB-related services that are started with amandabackup user will fail to start with 'Logon failure' errors, and your backups will fail.

If the ZCB machine is not part of a Windows domain

The ZCB Services run under 'amandabackup' or 'localcomputer\amandabackup' credentials.

  1. The Administrator must change the amandabackup user password on the Windows system.
  2. Launch ZCB and run the "Update Password" command. This will automatically do the following:
    1. Update the password in the internal ZCB database.
    2. Update for the background ZCB services
    3. Restart the background ZCB services

If the ZCB machine is part of a Windows domain

The ZCB Services run under 'domain\amandabackup' credentials.

  1. The Administrator must change the amandabackup user password in Windows Active Directory.
  2. Launch ZCB and run the "Update Password" command. This will automatically do the following:
    1. Update the password in the internal ZCB database.
    2. Update for the background ZCB services
    3. Restart the background ZCB services
  3. If there are other machines on the domain that run ZCB, repeat step 2 for all of them. Failure to update the password within ZCB will result in Logon Failed errors.
