First-Time Setup - Desktop Backup, powered by CrashPlan


This document provides first-time-setup instructions for MiWorkspace customers to install and set up CrashPlan on a MiWorkspace computer.

  • Eligible MiWorkspace customers automatically have a Desktop Backup account provisioned for them, but still need to download and install the CrashPlan client from Software Center and configure their backup settings.

Important! The University of Michigan Medical Health Information Technology & Services (HITS) also uses CrashPlan for a service called Data Guard. This document and the ITS Service Center do not cover the use of this service. For more information, please contact HITS.

    Windows: Click the Start menu, type CrashPlan in the search box, and press Enter.
    Mac: In the Dock, open Finder, click Applications, and then click CrashPlan.
  2. If prompted, enter your full UMICH email address ([email protected]), and then click Continue. Otherwise, skip to step 3.
  • To sign in using a shared account, enter the shared account name and append to the end.

Client Configuration

Initial Backup

  • Your initial backup should be performed on a fast network (e.g., U-M hard wired or MWireless network) to minimize time. Large single files typically upload at a faster rate than many small files. Each gigabyte of data will typically take 1.5 hours to complete.
  • You can select multiple locations to include in the backup. Your Users folder on your computer’s hard drive is selected by default.
  1. Click Manage Files.
  2. Click the checkboxes to select the folders you want to back up.


  • It is not necessary to back up the entire hard drive as CrashPlan cannot restore full operating systems. Nor is it necessary to select already backed-up locations, such as Box Sync. 
  • Select the Users folder with your uniqname, as well as any other locations you regularly save files.

  1. Click Save. Your backup will begin immediately.
