    Last update: 10-10-2022


    To troubleshoot cloud backup issues, you will need to troubleshoot the connection from the bootable media or Virtual Appliance to Acronis Datacenter.

    Starting from Acronis Cyber Protect 21.07, Virtual Appliance and bootable media contain built-in tcpdump utility for collecting network tracing logs.


    To capture the tcpdump log you will need to perform the following actions:

    1. Start the command shell, press CTRL+SHIFT+F2 while in the bootable media or Virtual Appliance UI.
    2. Issue /bin/sshd to start ssh daemon.

    3. Connect to the media using SSH client (like WinSCP or Putty)

    4. Start logging of tcpdump utility:

      # tcpdump -i eth0 -s 64 port 443 or port 44445 -w /var/lib/Acronis/tcpdump.pcap

    5. Reproduce the issue
    6. Press Ctrl+C to stop tcpdump logging
    7. Download the created dump from /var/lib/Acronis using WinSCP.
