Exclude networks used for backup

Applies to:
  • Code42 CrashPlan (previously CrashPlan PROe)

Overview

You can prevent the Code42 CrashPlan app from backing up over specified network adapters and wireless networks. For example, this is useful if you want to prevent CrashPlan from:

  • Backing up over a slow VPN connection
  • Backing up through a data card that could result in overage charges from your wireless carrier

This tutorial provides a step-by-step guide to excluding network adapters and wireless networks.

Considerations

  • This article assumes you have permission to change your network preferences. Your administrator may lock these settings.
  • The CrashPlan app uses the primary network interface assigned by your operating system. If the primary interface is excluded, the CrashPlan app blocks backup activity, even if other network interfaces are available.
  • Only backup activity is prevented when your device is connected to an excluded network. You can still download files when your device is connected to an excluded network.

How exclusions work with multiple active network interfaces

If you have multiple active network interfaces, CrashPlan will use the primary network interface assigned by your operating system. Like most applications, CrashPlan relies on the operating system to choose the interface it uses. If the primary interface is blocked, the CrashPlan app will block your connection, even if other network interfaces are available.

Network exclusions in CrashPlan work as follows:

  1. CrashPlan asks the operating system to make a network connection to the Code42 servers.
  2. The device uses the interface that is listed by the operating system as the primary network interface.
  3. CrashPlan tries to use this connection to back up.
  4. CrashPlan checks its list of network exclusions. If the connection is excluded, it blocks the connection, and displays the message: Network blocked - Backup will resume automatically on approved networks.
