Hi, Don't know anything about configuring WOL, but... - It is not something buildin in TSM; - If you configure some station to power on these machines back-ups can be performed; - If you configure your clients to be in TSM schedmode=polling and the startup window of the schedule is large enough, your back-ups will run as scheduled. With prompted you have the posseblity that if the clients is starting up a little to late, the back-up schedule will be marked as missed.
Hope that this helps.

Yours are valid concerns but I only manage the TSM and was asked to find out about WOL. In the meantime we are planning to inform the users about the situation and ask them to leave the machines running overnight at least from time to time so that we have some backup. Thanks again. -- S pozdravem Michal Mertl ICZ a.s.
