for backup? I have seen 2 or 3 free ones recommended. I have always used Cobian backup. It has been recommended for years. It does incremental backups and is configured like YOU wish.

When we had a serious problem on one computer a few months ago, the tech geek who came out said that Cobian is what THEY used.

Karen Kenworthy's Replicator also gets good reviews, but I have never tried it.
