Another problem I see with Windows 7 clients is too aggressive power management turning off the Ethernet interface even though it is in use by bacula-fd. Apparently there is some Windows system call that a service (daemon) must make to tell Windows not to do power management while it is busy. I don't know what versions of Windows do that, other than 7 and Vista, but it is a potential problem. ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
