Retrospect clients on the network
Authored by: lionel77 on Oct 15, '04 12:41:41AM
It's pretty annoying that Retrospect (6.0.193) is not able to wake up os x network clients, effectively preventing them from being backed up if they are sleeping. Dantz recommends to turn off the energy saver but that's not really an option in my opinion.

The solution:
Get wakeonlan (it's included as a compiled version in wake550).
The syntax for wakeonlan is pretty simple, e.g.: wakeonlan -i 127.0.0.1 00:0d:93:a6:75:b2
(the first parameter is the ip address of the machine you want to wake up and the second parameter is its Ethernet-ID/MAC-Address; you can get both from System Preferences->Network)

Now all you have to do is run wakeonlan via cron a minute before Retrospect is scheduled to run. If you are not very familiar with cron take a look at CronniX.

Hope this helps somebody to save some time and/or money on the electricity bill...

DON'T include the ip address

at least in my local network here wakeonlan fails if you send packages to a specific ip address and that computer has been sleeping for more than 15min or so...
so just incude the mac address as a parameter.

oh, and i also noticed you can get wakeonlan now via fink. the package is called "wakeonlan-pm".

I set the Mac to start up a few minutes before the scheduled back-up time using Energy Saver-->Schedule-->Start. This wakes up the computer when it's running and the back-up takes place normally.
