Client Configuration

First-Time 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.

  1. Click the checkboxes to select the folders you want to back up.

Note It is not necessary to back up the entire hard drive as CrashPlan cannot do full operating system restores. Nor is it necessary to select already backed up locations, such as Box Sync. Rather, select only locations where you regularly save files.

  1. Click Save. Your backup will begin immediately.

Important! Users with macOS 10.14 Mojave and above must complete the following additional steps in order to modify your CrashPlan settings and back up your data.
