Hi All,
Hoping you can help. I have two OMV servers at home, a main and a second that backs up everything from the first once a month. I want to avoid having the second on all the time and using power, spinning disks for no reason.
I thought that the best way to do this might be to have the backup server "sleep" after the Rsync job is completed. Then, in a month's time, Main server wakes the backup server in preparation for the next sync.
So my question is, what is the easiest (software) solution I might use? The only thing I can find so far is using the autoshutdown plugin on the backup server + WOL from main. My questions are;
1) Is this the simplest solution?
2) Does WOL only wake a server from Sleep, or also from being shutdown? I am not sure if the proposed combo would even work
3) If the above is all good - What autoshutdown argument is best to identify if rsync is running / done? Is there some flag I can use, or do I need to look at Hdd activity somehow?
