CrashPlan requires system resources to encrypt, compress, and de-duplicate your files before sending, and also de-encrypt and decompress when you Restore. You can adjust the amount of CPU CrashPlan can use, depending on whether you want to conserve resources or allow jobs to run faster.

How much CPU does CrashPlan need?
We recommend you set at a minimum the Away CPU usage to 50% and the Present CPU usage to 20%.
When you are Restoring a lot of files, or if your backup is slow, consider setting the Away usage to 85% or higher and scheduling your backup or running your Restore when you are not active at your computer.
You should not set CPU to the absolute minimum or maximum. This can cause issues with your backup.
When is the user "present" or "away"?
CrashPlan uses input activity to determine if a user is "away." A user is "away" when there is no keyboard and mouse activity for the amount of time you set in the User Is Away When Not Active For setting.
