I used to work from a shared office, and the cleaning lady just asked me to help sell some of the old stuff that was left behind by a tenant that has moved out. Included were 2 generic UPS units. Near as I can tell it is made in China by Voltronic Power, and then rebranded by the local (to the origin) seller. (Strange setup, the sockets are US style 3 pin, but the voltage is 220Vac)


Batteries were dead, (12V, 4.5Ah) but measured and saw that there is space for a larger battery. So upgraded to 12V, 7.2Ah costing RM 55.


Plugging in the UPS via USB cable, and the Synology recognises the device.


Both when mains power, or when battery power.


One thing I noticed is that the NAS does not shut down after the specified time. It just unmounts the HDDs and shuts down all services, ready for a power off. You can ensure power off when you check the box "Shut down UPS when the system enters safe mode". The UPS will power off. shutting everything down.


If you don't check the box mentioned above, and check at this "Restart automatically when power supply issue is fixed" box instead, the Synology will restart all the services and wake the HDDs, ready for action again after mains power is restored.


So that's my experience with a UPS (with USB connection) on a Synology (DSM v6.2.4-25556). I now think any UPS with a USB that does reporting can be used, and the advice I got from the All IT Hypermarket person previously is incorrect. Unfortunately I won't be testing with the Right Power model I was previously interested in anymore, since I have these 2 UPSs.
^{~~~ Sekian report of my experience ~~~}

For a Synology NAS, most APC UPS will work. Just get the cheapest APC UPS with USB communication capability. What I did, I 'enlarge' the battery capacity by using larger 12v battery. Put the battery outside UPS. Longer backup time with cheaper price. The 7.2Ah 12V SLA battery cost about RM50 a piece. Double that - it's just an additional RM50 for nearly double the capacity.

The battery is bigger than the UPS for my NAS.

12V 65AH lead seal battery.

Waaah Can sustain for hours.

I have similar UPS like in your picture too. Use 2 7.2Ah 12v battery only.

As an EE, I'm going for multiple smaller, more common batteries, instead of one large single battery. Buying a 65Ah battery online shows prices starting at RM 435, with the average being about RM 500. 9x units of 7.2Ah batteries costs about RM 450 - RM 500, getting almost the same capacity as the large battery. Costs me almost nothing in materials as I already have it, and a bit of my time, to wire them all up.
The real question though, why do you want your NAS running for 24 hours during a power outage?

That's a good info. Maybe the guy bring it from his country that is Lebanon or Philippines.

Almost 10 times the capacity

Can also power the router and other network components. The network will never have any downtime.

fuh that's huge everything can remain online when power breakdown

The NAS is access by my friend and family. I share my pic, video and contain.

The battery is for Solar system. Got 2 set. 1 spoiled. So left this I use it for NAS lor. The battery lifespan actually left not much..

Almost 10 days my NAS in degraded conditions hopefully tomorrow the rma disk arrive and will be ok.

Just curios, should I just insert & populate the new disk or better create whole new volume

After all I want to go with Raid-6 and now Raid-5

If you got backup at other place then can just delete the RAID and create new one so that no need do twice.

Yes I've got backup still waiting arrival haiyaa feels very slow

ok the rma just arrived

I am wondering, anyone of you looking for a 6TB WD Red? I got one brand new extra looking to sell.

sorry to say that the hard disk u want to sell is SMR drive, totally not recommended for NAS users

My NAS has 2 set of 6TB WD red brought in 2014. Mix running with sg iron wolf 16tb.

Any problem? I m waiting it to die and replace it. 6yrs is almost end of the lifespan.

What actually is SSL Certificate it seems expired or not match between Synology apps

Oso received email to renew the certificate for the "mydomain.synology.me"

A Beginner's Guide to SSL: What It is & Why It Makes Your Website More Secure

If you connect from internet to your NAS and using DDNS or your own domain you'll need SSL certificate to make it secure. If connect through QuickConnect or not access it from internet then don't need it.

I'm not sure wat I tekan2 then change it to DSmy.me suddenly it's renew till July 2021 so temporary resolve

if from office computer access thru QuickConnect only the Android Apps require the certificate when access from outside home networking

I been using SSD drive as the storage for files in Drive and Moments for more than a month now. Before this it store in HDD. I always open files ranging from few hundreds kilobyte or few megabytes, or loading thumbnails for pictures, with HDD it always takes few seconds and feel laggy. Especially more when I access it remotely. I also got nvme cache but it can't cache all the files all the time. Now with SSD it's noticably faster, no more waiting few seconds for it to load the files or thumbnails.

Since I'm only using 1 SSD, there's no redundancy, so what I do is I set Hyperbackup to make backup of Homes folder every hour.

Having SSD for your active folders is worth the upgrade for NAS in my opinion.
