Windows XP and Windows 2000 Professional Machines do not require a RAWS (Remote Agent for Windows Systems) License, but the Remote Agent must be installed on the machines to be able to fully back them up. Windows Server Edition, Vista and above workstation machines require that RAWS be installed on them and a RAWS License be available for each machine being backed up.
Backup Exec 12.5 and above now has the ability to evaluate individual options after the core product license has been installed. The evaluation countdown for these options also does not begin until the first backup using this option runs (prior versions could only be in either evaluation or licensed mode for all core and product options & the 60 day evaluation counter started to decrement from the time the software was initially installed).
If only the media server gets backed up after Backup Exec is installed, the count for the Remote Agent for Windows Systems will remain at 1 of 60. If any remote machines are added to the backup selection list, the count will begin to decrement from the time the first backup of those remote Windows Machines run, regardless of which operating system (Windows 2000 Pro, XP, Vista, Windows 7, Windows 2000 Server, Windows 2003, or Windows 2008) is installed.
After the 60 day evaluation period has expired, the backups of Windows XP and 2000 Pro computers will continue to run. Additional machines with those operating systems installed can also be selected in the backup selections list and can be backed up successfully. Any computer with an operating system newer than Windows XP or 2000 Professional (Windows 2000 Server, 2003, 2008, Vista, & Windows 7) will fail to be backed up because the evaluation period will have expired. A valid Remote Agent for Windows Systems (RAWS) License will need to be obtained and entered on the media server to be able to successfully back up machines with these operating systems or to be able to make new selections for them in the backup selections list.
