I started using SugerSync yesterday, so this is a timely discussion for me. I'm using it exclusively for backing up my Calibre library. Observations so far:
- Sign-up and installation was painless.
- Multiple upload speed options are efficient. "Fast" really does utilize the maximum bandwidth, as evidenced by the fact that my VOIP ceased proper functioning (and also by network usage numbers). "Slow" keeps the files moving but keeps it from interfering with other network traffic.
- I like the interface, but that is subjective and some might find that some things are not intuitive.
- I like that they offer more free space than the other top companies.
So far, so good. Does what it's supposed to without any apparent issues. I decided to try it because my Calibre library changes more frequently than anything else on this computer, and backing up to an external drive was getting tedious. I still plan to do that, but on a much less frequent schedule.
