    Unable To Back Up - No Connection For X Days

    Applies to:
    • CrashPlan for Home
    • CrashPlan PRO
    • CrashPlan PROe

    Overview

    When your computer is unable to connect to a backup destination, the CrashPlan app displays the message “Unable to back up - no connection for X days” for that destination. Additionally, you might receive an email alert notifying you that the computer “has been unable to reach any backup destinations for X Days”.

    Follow the instructions in this article to troubleshoot the issue. 

    Diagnosing

    If you have multiple destinations, you can identify the destination with connection problems from the Backup tab of the CrashPlan app. Check the circle next to the destination's name:

    • Green File:CrashPlan/Latest/Troubleshooting/Unable_To_Back_Up_-_No_Connection_For_X_Days/Screen_Shot_2014-05-14_at_4.40.16_PM.png means the destination is connected
    • Gray File:CrashPlan/Latest/Troubleshooting/Unable_To_Back_Up_-_No_Connection_For_X_Days/Screen_Shot_2014-05-15_at_8.06.16_AM.png ​means your computer can't connect to the destination 

    Recommended Solution

    This issue can occur for a number of reasons. Follow the instructions below in the order they are presented.

    Re-authenticating With The Destination

    1. Open the CrashPlan app
    2. Double-click the CrashPlan logo in the upper-right corner
      The CrashPlan command-line area opens
    3. Enter this command: 
      ra, restart
    4. Press Enter
      This closes the CrashPlan app, stops the CrashPlan service, and then restarts the CrashPlan service

    ​​Reconnect

    Uninstall And Reinstall The CrashPlan App

    If re-authenticating with the destination did not resolve the issue, perform a standard uninstall and reinstall of the CrashPlan app. A standard uninstall does not affect your existing backups. 

    Troubleshoot Network Connection

    If the previous recommendations did not resolve your issue, follow the instructions below for the type of destination affected.

    Cloud (Online) Destination

    If you are unable to connect to a cloud destination (e.g., CrashPlan Central), please see our network troubleshooting article to identify and resolve the issue.

    Computer Destination

    If you are unable to connect to a computer destination, refer to our guide on Connections Between Computers

    Only Backing Up An External Drive?
    In rare scenarios, this issue can occur when the only files selected for backup are on an external drive that isn't currently connected to the computer. Connect the external drive to resolve the issue.
