I have a backup server which gets waken up by a wake-on-lan packet, then pulls the files from the clients and then goes back to sleep again.
Sometimes I wake it up via WOL and want to keep it on for a couple of hours.
When in the meantime a backup gets triggered, then the backup script sends the server back to sleep, which I don't want, as I had the intention to send it to sleep manually.
I don't want to set/unset a flag in a file, but have the server know that this backup did start while the server was already on for at least a couple of minutes and therefore should not be sent to sleep.
I figured out that the network interface status dialog contains a "duration" field, which is a good indicator for how long this interface has been up, which equals the time the server has been awake.
How can I access that information programatically, preferably through a python script?
