There is also a possibility to use it from a WinPE boot CD (explained in the Link too), or you can make yourself a UBCD4WIN which should also have the tool included:

You probably won't be able to get this or other tools to run from a Windows 2000 box while the OS is up, as that OS didn't yet have Shadowcopy available. So for that OS you will always have to do a partition backup from the CD.
