Putting NAS to sleep from /sys/power/state

[ktlin]

Hi!

I'm looking to do some regular automatic backups from my Linux laptop using rsync. I always keep my NAS in Sleep (S3), so I made a script to:

• Wake on LAN
• copy data with rsync
• Put the NAS back to sleep

, which would be called once per day.

For the "putting the NAS to sleep", I simply write "mem" through ssh to /sys/power/state and that puts it to sleep.

Now my question: Is this safe?

I noticed when triggering the Sleep from mobile app or Control Center, it takes a bit of time to prep things, and after around 10-15 seconds, it goes to sleep.
When I do the /sys/power/state method, it goes (almost) instantly.

Is there anything I should know, or anything that I'm missing?

Thanks!

You should call this instead, to let the system handles the way it's designed during STR.

Code: Select all

/etc/init.d/NASsuspend

Thanks!

This is exactly what I needed and for some reason, I couldn't find this info anywhere before.
