Instant sync only works for local folders it can monitor. Since it doesnt have a client on the other end, there’s no way to make this happen (it would have to monitor the destination).
This would require keeping a connection open between devices, which is a high cost from a network (and especially battery) perspective.
Its a great app, I’ve used it for 10+ years, paid for it 2 or 3 times because it’s worth it.
Nothng official, sorry, wish I did!
Mostly personal experience. But that experience is also shared among a group of peers and friends in the SMB space where their clients think they can keep stuff on externals in an office safe only to find they’ve gone tits up nearly every time they pull them out a couple years later. And not the enclosures, the drives themselves - they all have external drive readers for just these kinds of circumstances.
In the enterprise you’d get laughed out of a datacenter for even suggesting cold drives for anything. Of course that’s based around simple bit rot concerns, and why file systems like ZFS use a methodology to test/verify bits on a regular basis.
If nothing else, that bit rot should be enough of a reason to not store data on cold drives. It’s not what drives were designed (or tested) to do.
Meh, you got a spare kidney…
If the NAS is always making noise then it’s not parking the drives. Check the config - I’m not sure QNap does drive parking by defaut if at all. Fron what I’ve seen, they’re a Business Class solution first, consumer second (I have friends in the SMB space, QNAP has been a common solution for their clients), business doesn’t want drive parking.
I have an ancient Drobo that does parking and uses a large fan (so it can run at lower speeds, meaning quieter) - with 5 drives I don’t hear it over ambient room noise (the fridge is louder).
Give us some numbers on space. My NAS is 8TB that I keep 20% free (It complains with less free space and performance drops), my server has an 8TB data drive, with two 4TB externals attached. I replicate data from the server to each device on a rolling schedule for data redundancy, and also use a cloud backup for the important stuff (less than 1TB).
The point I’m trying to make is maybe you don’t need a RAID NAS right now if your critical data size is below available single-drive capacity, and may be better served by multiple drives and cloud backup. (Also, a NAS is still a single point of failure - RAID isn’t redundant data it’s redundant drives. Even with ZFS it’s still a single data store that can fail, which is why businesses still have backups of their RAID systems).
To paraphrase an old racing saying: quiet costs money son, how silent you want it to be? 🤪

I would definitely keep them warm, as in a running machine.
Drives on a shelf die more often than always-on drives.
I self host on a 5 year old Dell Optiplex Small Form Factor desktop.
I also have a Raspberry Pi, which has about 1/16 the performance of the desktop - Pi can be used for all sorts of stuff.
Yep.
My Pi is about 8 watts. Really hard to beat.
The SFF started at 12w, but swapping out the data drive for a much larger one pushed it up 5w. And now with 2 VMs always running (PiHole and a Windows VM), it hovers at 20w.
The ancient NAS (Drobo) sits at about 15w.
The number one thing you can do, by orders of magnitude, is to start with power-friendly hardware.
For example, my previous server was an old gaming machine. It’s lowest idle power consumption was 80 watts. That was with running an OS that permitted heavy power reduction control, and enabling every power saving feature in the BIOS.
Compare that to my 2019 Dell Optiplex Small-Form-Factor desktop I’m running as a server. The power supply is rated for 80 watts, MAX. It idles at 20w, peaks at about 70w when converting multiple videos simultaneously. This with an 8 TB enterprise drive for data.
So 1/4 the power draw when idle, where it spends perhaps 90%+ of its time. Even things like Resilio Sync and Syncthing don’t significantly raise CPU time.
Streaming with Jellyfin or Mediamonkey have nearly no CPU impact.
There’s nothing in heavier hardware you could tune to get down to 20w.
That’s not data redundancy - there’s still only one copy of your data.
Those are mitigations against loss of data due to loss of parity.
There’s still only ONE copy of your data.
Fine.
Pull 1 drive and see how redundant your data is while it’s resilvering.
RAID is NOT data redundancy. You still have a single copy of your data.
RAID isn’t data redundancy, it’s an array of drives combined to form a single logical storage pool. It solves the problem of needing a single storage pool larger than the available drives. As such, it’s very sensitive to loss of a single drive.
At your storage size requirements (2 TB), RAID is unnecessary today.
Unless you need the super-compactness of a mini PC, the Small Form Factor is a significantly greater value.
You get more horsepower, more space, and better cooling.
And they tend to be very quiet. Mine only has some fan noise when converting video, and it’s always running 2-5 VM’s (mostly Windows).
I disagree with cold backup drives.
In my experience, cold drives fail more often than warm drives. This is why all my data replication is always warm.
All backup solutions should be regulator tested, otherwise you don’t know if you have a backup.
Others have mentioned backup, I’m going to reiterate that.
I have an (old) NAS that frankly I don’t trust to not die. Then again, anything can die, so it’s just one component of my data duplication.
I also have my server which is authoritative for all data, which is then duplicated (on schedules) to the NAS and 2 external drives, so I have 4 local copies.
All mobile devices sync important data to my server.
Power
My NAS idles about 15w. It’s 5 drives, so honestly that’s quite low and tells us it spins down drives.
My server idles at 20w, using NVME as the boot drive, a large data drive, and an SSD for virtual machines. It’s power supply maxes at 80w (which it approaches when I’m converting videos with handbrake).
Before this my server was an old gaming desktop that idled around 100w.
So my server today is a 5 year old Small-Form-Factor Desktop that I picked up for $50. I paid more for the RAM I added. It has enough room internally for one 3.5" drive and the 2.5" SSD…
It’s also quiet - the CPU and power supply fans double as case fans.
Oh, agreed.
There’s some other stuff at play with the minis (shared family photos, backup to each other, etc) that I’m going to use as an enticement to get them to learn to use these tools.
Once they learn that, I can slip in some other things, piecemeal, depending on what each person clicks with.
Bold move, Cotton!
(Not really, Lineage updates are the most seamless I’ve ever seen).
Uggh, feel bad for them.
I’ve tried for years to get friends and family to have their data sit in a single point in the house and use backup services. That would be a massive improvement.
Family won’t listen, so I’m building minicomputers for them all that will handle it. Just have to configure their devices to store data there.
Yep.
I run Tailscale on every device that can run it, and have a TS router in one device at home for devices that can’t run it.
Its my fallback Syncthing every has a Discovery server failure.
