Despite having servers in NZ and a fast upload speed compared to overseas services, Backflip has a whole lot of negatives. Firstly, they haven't responded to any of my emails over the last week. There is no phone number to call if you run into problems. I'm currently not able to connect for some reason, but there is nothing I can do about this except spend time troubleshooting the problem myself (I thought backup solutions were supposed to be simple, and set-and-forget). The software backed up for a short time, but then collapsed, claiming it couldn't find the server.
Secondly, the software is butt-ugly and looks like someone thew it together over a cup of coffee one afternoon. I'm heavily critical of crapware. This may not be an issue with some people.
Thirdly, they took my money for an upgraded service ($5 per month) and provided no service. I'm still on the free trial service, limited to 1 GB. I think that's just plain dishonest business practice. I've e-mailed every address that I can find that is connected to the company, asking that they cancel my account. They did have my credit card recorded in their system, but there appears no way to delete the number. As such, I had to replace my real credit card number with a fake number on their web site so they wouldn't keep charging me.
Not a nice story to tell, so buyer beware. I've given up on getting my $5 back.
