Wake on LAN

Posts: 3 · ffslaz 23 Feb 2024, 07:57

I am trying to sync with a NAS that has its disks set to spin down.

Is there any way I can run an external program, such as a "Wake on LAN" utility prior to running my FreeFileSync batch?

WAKE-UP-NAS.bat:

WakeMeOnLan.exe /wakeup NAS

That WakeMeOnLan utility from Nirsoft is the one I currently use with the internal IP address of the NAS specified.

Could this and the FreeFileSync batch config file be combined together in an old fashioned DOS batch file?

I think I would need a pause/delay function to wait until the NAS has woken up though.

First, I like this program a lot. (In fact, I made a donation.) Recently, I upgraded a couple of PC's so they can run on Windows 11. These are used only for backup purposes and run 24-7. In order to reduce power consumption, I have activated power-saving profiles that put the machines to sleep. I would imagine this is fairly common for users. As a result, when I try to run FreeFileSync, there is a failure to recognize these PC's as they are asleep. After sending wake-up packets (using either EasyWOL or WakeMeOnLan), there is no difficulty. It seems that a fairly easy programming addition to FreeFileSync would be an option to send a MagicPacket wake-up command to designated backup destinations and perhaps a delay setting under the Tools-Option menus. In my experience, it appears to take about 5 seconds for these devices to wake up. One of back-up PC's uses a Nvme SSD while the other one uses conventional electro-mechanical hard drives.
