<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">In both hibernate and suspend mode, your computer isn’t doing anything productive, and won’t run any background processes AFAIK.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Hibernate stores the state of your computer on disk (IIUC, its stored (at least partially) in the (first) swap PARTITION, which means you need to have a ‘big
enough’ swap partition for hibernate to work, and indeed for hibernate even to be an option when you ask your computer to go into a lower power mode, again IIUC), and then powers off the computer. Resuming from hibernate takes a while depending upon the size
of ram and the speed of disk. If you’re ‘lucky’, you can see your computer take a trip through grub on the way up.<o:p></o:p></span></p>

no network answers, nothing. Resuming from suspend is REALLY FAST, looking almost like it is coming out of screensaver on some machines. And no trip through grub.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Screen save mode means that your video output is shut down. On some video cards (at least one of which I’ve had the misfortune of having), this is a condition
that can only be exited by a reboot, which means that screensave mode with that video card is a call for a hard power cycle…

works correctly, as I said).<o:p></o:p></span></p>

your computer effectively turns off when it goes to sleep.<br>
<br>
tcp connections such as rsync might continue if you bring the computer out<br>
of sleep soon enough. Most likely you'll have to restart the rsync as the<br>
tcp connections will have timed out. rsync might also have controls to<br>
require re-authentication.<br>
<br>
rsync will continue from where it left off once you restart it.<br>
