05: Adjust settings for optimal backup

This article applies to Code42 for Enterprise version 4.


CrashPlan is designed to make minimal demands on your computer's resources. These initial settings favor quiet, background operation over speed. While entirely possible to complete your initial backup with these settings, many people want their initial backup to complete as fast as possible.

We've outlined a few helpful settings below for speeding up your backup. You can reverse these settings at any time, but we recommend keeping them enabled until your initial backup is complete.

Prevent your computer from going to sleep

If your computer is asleep or turned off, CrashPlan doesn't run and therefore can't back up or restore files. Follow the link below for your operating system for instructions on disabling sleep for your computer:

Some OS X devices can hibernate and some Windows devices can "power nap." The CrashPlan app cannot back up or download files during these states.  

Adjust CrashPlan app settings

In addition to preventing your computer from going to sleep, we recommend adjusting the amount of your computer's processing power (CPU) CrashPlan is allowed to use. You can distinguish between the percentage allowed when you are working on the computer (present) and not working on the computer (away).

How does CrashPlan know I'm away?
The CrashPlan app uses keyboard and mouse activity to detect if you are present or away from your computer.

  1. Open the CrashPlan app and go to Settings > General
  2. Increase the CPU percent for both away and present (for example 90% and 60%)
    Note: In Linux, CrashPlan always uses the “Away” setting
  3. Click Save

Adjust CPU percentage

Find the percentage that works for you
If you notice that your system slows down or interferes with your work, you can always scale back the percentage CrashPlan is allowed to use.

How much can I expect to back up to CrashPlan Central in a day? (CrashPlan for Home only)

On average, you can expect your CrashPlan Central backup to progress by at least 10 GB of information a day, as long as your computer is powered on and not in standby mode. That's the equivalent of:

  • 6,800+ photos from a camera phone (at 1.5 MB per photo)
  • 1024 photos from a DSLR camera (at 10 MB per photo)
  • 1500+ MP3s (at 6.5 MB per song)
  • 8 full-length standard definition movies (at 1.2 GB per movie)
