Initial backups do take a little longer than usual backups since CrashPlan creates a copy of your archive in the cloud. Once your files are backed up, CrashPlan will only upload new/updated files. Normally, CrashPlan backs up at a speed of 1-3 mbps or 10-30 GB a day.

It's important to remember that like other services that share resources with a pool of users (i.e. cable internet or cellular data), CrashPlan's speed varies depending on the number of simultaneous users and what they are uploading or downloading at the time. Though we do prioritize the downloads from our server, we are still bound by the number of users that are currently uploading or downloading from that server.

If you happen to have a very fast internet connection, it is unlikely that backups or restores from CrashPlan Central will be able to match your upload or download limit. This is not a bug - it's the nature of a shared service that is designed to be affordable. We work to ensure that everyone gets sufficient bandwidth for a very reasonable price.

We're continually monitoring usage across our data centers and we are strategically adding capacity (servers, storage and bandwidth) to our infrastructure to deliver the best upload speeds we can while preserving our competitive pricing.
