Solution

• Make sure that WoL is enabled on the target machine. See Enabling Wake-on-LAN;
• Check the following known issues:
  • Acronis Backup & Recovery 10 Fails to Start a Scheduled Task On Wake-on-LAN
  • Wake-On-LAN Does Not Work after Hard Shutdown
• In some cases, you may notice that WoL does not work on a large number of computers at the same time, but it works on a small group at a time. This could mean that a switch or a hub is programmed to block the magic packet in case it detects too much traffic. Back up small groups of computers at a time.
• If the issue persists, capture the network packet to send it Acronis Customer Central along with your support request:

  Capturing the network packet

  The network packet can be captured and identified by the free software called Ethereal.

  1. Download Ethereal, which is open source software, from the following location available for various platforms:
