    In case you know that backup will not fail immediately, it means WireShark should be executed during some extended time (20 minutes +) it is a good idea to write the information to a file right after start. You can choose a file in the Output tab and set traffic and time limits for logs collection:

  4. Reproduce the issue without closing the Wireshark application:

  5. Click Capture -> Stop after the issue is reproduced:

  6. Contact Acronis Customer Central and attach the saved log to your request. Also please let us know the IP address of the source and target device.
