This article describes the solution for a known issue in which the CrashPlan app does not apply the TCP packet QoS priority settings.
Code42 environments that both:
- Use IPv4 (or a mix of IPv4 and IPv6)
- Use CrashPlan app version 4.7.0 or later
- This solution is only available for devices using CrashPlan app version 4.7.0 and later.
- You must repeat these steps each time you upgrade the CrashPlan app. These changes are reverted during the upgrade process.
Before you begin
For customers with an on-premises authority server, you must upgrade your Code42 environment to Code42 server version 5.3.0 and CrashPlan app 4.7.0 or later.
To enforce the TCP Packet QoS setting:
- On the device where the CrashPlan app is installed, navigate to the CrashPlan app configuration file:
- Installed for everyone: C:\Program Files\CrashPlan\CrashPlanService.ini
- Installed per user: C:\Users\<username>\AppData\<Local|Roaming>\Programs\CrashPlan\CrashPlanService.ini
- OS X
- Installed for everyone: /Library/LaunchDaemons/com.crashplan.engine.plist
- Installed per user: ~/Library/LaunchAgents/com.crashplan.engine.plist
- Linux: /usr/local/crashplan/bin/run.conf
- Open the file in a text editor.
- Add this line to the configuration file: Djava.net.preferIPv4Stack=true
- Save your changes.
- Restart the device.
