Nas Synology waking up from sleep

Solved

Hello,

my Synology DS218J NAS wakes up by itself several times a day. What could be the reason for this?

In sleep mode, the NAS is like this: the LAN light is on, and all the other lights are off.

Thank you.

Configuration: Windows / Firefox 71.0

    To respond, it is that there is an activity, even for a few seconds on the network.
    It can come from anything on the network recognized by the NAS.

      If it is configured to connect to the internet (default gateway), yes, it is likely to receive quite a few ARP packets.

        It is, at my place, but it's a default setting at Synology, which also uses its own system for internet access, for example. (my provider doesn't allow this in principle, with the Syno there's no need to 'fiddle' with Dyndns for instance)

        That said, based on my experience, it doesn't seem to do anything; the Syno only seems to react if it detects activity on the LAN/wifi from one of the recognized PCs/machines in the workgroup. (I have several machines + a smart TV + a Popcorn box, a LAN printer, an IP multimedia box).

        That said, I don't really have a box. :-)
        I still have a 'simple' (Cable) modem + a router + 2 switches + a wifi access point, each "independent" and physical.
        Maybe it's not quite the same...

        If it's somewhat similar, if you have a router.
        But if it's configured to connect to the internet, it will definitely pick up ARPs from the router, not just from LAN machines, but if the IP stack remains active, it may only restart when prompted by a LAN client.
        On the other hand, if it uses some kind of VPN to go through Synology routers to access the net, that raises concerns for the stored data, as we can no longer really control their security if Synology manages its machines as it pleases.
        I wouldn't want to have personal files stored there.
        At that point, we are no longer operating a server at all; we are getting closer to a cloud service, without any guarantees.

    Not wrong about mastering it, but Synology makes equipment for both individuals AND businesses (we also use it here for specific uses). So they have little interest in messing up, and like any professional collaboration, there’s a minimum of trust involved.

    For example, my "sensitive" personal data (I mean the kind I don’t want to lose even if I get robbed) is stored with Spideroak. It's cloud storage but with local encryption (and other benefits for me). It's a bit "slower" but when you subscribe, you know (or should know) that if you lose your key, even they can’t access it; that’s clearly stated in the terms. They simply don’t have the double key.

    All of this to say that yes, depending on the situation, there will be factors you have less or more control over, based on what you choose.
    But also that paranoia is very marketable and mostly a scare tactic, and for 98% of private individuals, the clouds are much safer than at home, and Big Brother couldn’t care less about your Word files, PDFs, and other images. Unless you're scamming $2,000,000 a month or you're friends with a notorious terrorist.
    The only risk for them is losing everything and regretting family photos. AND for that, a current cloud is more than secure enough.
    In business, it’s different, but that’s another topic.

    So to me, Synology is more than sufficient for individuals. And having an access system managed by Synology or through a workaround where you "rent" a DynDNS, for the individual once again, will be "likely" more secure and especially less annoying with Synology :-)

    Security must be considered based on the criticality of the data (professionally, that’s what we do, right?). A minimum level of protection is needed anyway, but for the rest, Mr. Dupont can sleep easy if he follows a few basic guidelines.

    Happy upcoming holidays :-)

    Hi,
    what's the point of a NAS in standby?
    It's a tool like a box, a router, a switch, or a Wi-Fi access point; it should be operational 24/7, otherwise, it's useless—might as well get a removable USB drive.

      In fact, the NAS hard drive is visible 24/7 on the network. Normally, when only the LAN is on, I believe the hard drive is not in use, and when all the LEDs are lit, especially disk 1, it means that the disk is being used. It switches from LAN on to all LEDs. The hard drive is in use, but by what?
      This is my first NAS; I'm a bit lost.

      It helps save money.
      And it is in no way comparable to an external hard drive.
      On Syno and others, everything goes into sleep mode and only the LAN card remains 'active'.
      The sleep mode is similar to that of a PC but a simple sleep and not a "prolonged" sleep.
      On my Syno, it goes to sleep after X minutes of inactivity, makes sense, we are not in a business environment, so it doesn't need to be functional all night or while we are working.
      Waking up from sleep is very quick, as soon as it detects the slightest activity.
      The benefit in consumption is more than interesting.
      The advantage of the NAS lies in a whole series of other things. (Features on Synos).

      Yeah,
      having servers running 24/7 at home, I find it hard to imagine the opposite.
      If the hard drives stop, it's not great for their health; it's better if they keep running continuously.
      The same goes for all machines; it's better to run them 24/7 than to shut them down and start them up again.

      Hello

      Does your NAS back itself up?

      Yes, thank you, this should be explained more often:
      if we choose a NAS in principle, it is not for a cloud service, the cloud itself does that very well.
      By wanting to enter the field of their competitors, NAS devices lose their purpose.
      This is really dangerous for users who are not knowledgeable, they could be very surprised by the reach of their files.
      Not healthy at all.

    Everything is normal then, I don't have to worry.

    Thank you.

      "Normal" if that's the question, yes no worries.
      Just make sure that if you have enabled Syno access to access it from outside, you have set a password that is not 12345 or azerty or the name of the dog, children, and that kind of nonsense. But a strong password.

      Best regards
