How long will the backup take?

For the typical home user on a regular DSL/Broadband connection, data uploads to SpiderOak range from around 10GB-15GB per 24 hour period. This assumes no other very upload-intensive tasks are running at the same time. Upload speeds will vary greatly depending on your geographical location and bandwidth. Users with a lot of data that will compress and de-duplicate well or who are on a very fast internet connection may experience better upload speeds. At the same time, users in remote areas or those with slow connections could experience slower upload speeds.
