robocopy for windows nt only?

is robocopy for use only with operating systems with NT?

can i use it for windows xp and windows 98? like through a network?

and have any of you guys had any experience? good bad?

I need to find a good backup program, and a peer referred me to this program, but i have no idea what it is... so any of your advice or opinions would be appreciated.

 

We used robocopy during our conversion to Active Directory. It was set up to automagically copy the files w/o our interaction, so can't tell you how to set it up. We ran it from a floppy disk from the Windows XP command prompt as part of a batch/cmd file. We didn't use it on Win9x computers. (I believe Windows XP is Windows NT 5.1)

For the most part, it worked great, but once in a while it ended up deleting either the source files, the copied files, or both...
