Do you do a lot of photography in RAW format and save files in TIFF? I can use up more storage space in an afternoon of shooting than the average person imagines.
I do some photography but mostly it is because I have multiple computers to protect. My wife’s new laptop was the biggest driver since it shuts down when she closes the lid. I needed a realtime solution that would backup a the file as soon as she created it. Their software works great!
