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.
