Listed below are the requirements for backing up any remote Windows NT or Windows 2000/2003 computer using Backup Exec 9.x:
1. A Remote Agent license must be installed on the Backup Exec server, and the Remote Agent component must be installed and running as a service on the target server. One Remote Agent license is required for each remote server that needs to be protected.
If the Remote Agent license is not installed, resources on the remote servers will be grayed out and will not be available for backup.
2. The Remote Agent license is not required for backing up Windows NT and Windows 2000 workstations, but the Remote Agent component must still be installed and running as a service on Windows NT 4.0 and Windows 2000 Professional workstation computers.
3. Backup Exec service account must have permissions to back up files on the remote servers that need to be backed up, usually via the 'Domain Admins' group.
4. If a server that belongs to a workgroup is to be backed up, the server should have an account with the same account name and password as the Backup Exec service account, and this account must be added to the local administrator group.
