Interesting ... and with the push to do more with the "cloud" I'm finding these, seemingly little, exclusions becoming more and more of a reason not to believe in the cloud.
I hope someone from Carbonite is reading this - and can answer the simple question, "Why?"
Why exclude certain file types? Why allow videos to be backed up but only if manually flagged?
If I point my backup software to a folder and say, "do it", I expect everything in that folder is going to be backed up - not a hodge-podge of filetypes that only the service provider agrees to for some reason not clearly understood by users.
