I recently found myself backing up around 100GB of data.  I originally attempted to simply copy the folders onto my external harddrive, but quickly discovered how incredibly broken the Windows copy system is.  If Windows copy isn’t taking 12 hours to copy, it’s crashing and giving up on the first sign of failure.  This usually forces you to have to start from the beginning because you don’t know what files have been properly copied or which files are corrupted.  Enter TeraCopy.

WARNING: Don’t download from the creators homepage, it has a virus =(. This is a sad thing for such a great application.  Instead, try to find it on a safer site that scans their files for viruses.  I got mine from download.cnet.com.

I copied my content in a few minutes, not hours, and it never crapped out once.  This is a must-have for anyone who deals with massive amounts of data transfers.  One bad thing that I’d have to say about this freeware tool is that the interface is a little clunky and unorthodox, but it gets the job done.
