Anyone using Syncthing on Mac OS with Synology?

[fido]

Is anyone having any success running Syncthing on Mac OS Monterey with a network attached Synology NAS?

I read that Syncthing will not be officially supported on Synology starting with DSM v>=7. Syncthing had been running great for me on my Synology but when I moved it over to my Mac mini I just started having problem after problem.

I listed my initial (super) slow sync issues here:

Steps to speed up scanning?

Syncthing is running on a Mac mini (2018) with 3.2 GHz 6-Core Intel Core i7 and 32 GB 2667 MHz DDR4. It’s connected via ethernet to a Synology ds-418play with 2gb memory and ~ 24tb of WD Red (spinning) drives. There was approx 2tb of data in the cloud (and a local folder on the synology with a lot of folders and probably hundreds of GBs maybe a TB of data.) Scanning was blocking a MacOS security update (amongst other things) and I decided after watching it slowly making progress over many many …

But, things got even worse when I started downloading files. I went from being able to sustain >10 MBps when it was running on my Synology to now being lucky to get 1Mbps and it is constantly fluctuating and showing 0.

I assume this is related to what I read about here regarding the way Syncthing writes data.

Very slow transfer

The most important point in those is the last column of the last two tables - “%util”. It indicates how much of the time the disk (or array) in question is busy servicing a request. For the individual disks in the syncthing only case it’s about 45%. That’s ok, the disks seem to have more to give. But checking the line for md2 it’s at 99% - the RAID array is maxed out. I’m guessing the “lost” performance between that is in waiting. Given that RAID5 needs to both read and write both old data and p…

I love syncthing. It has been super solid. I was dissapointed having to move my local install to a Mac but was prepared. Unless I can figure out a way to speed this up this doesn’t look like a sustainable backup tool for me anymore (at least with a network attached device.)

Are people downloading locally to a folder on their internal HD and then moving over to the synology and deleting? I presume that might speed things up?

I can’t say much about your transfer speed issues, the description is too unspecific to pinpoint where to investigate.

Regarding the Synology package: The one on SynoCommunity just had a release yesterday and it is definitely supported for DSM 7. Don’t worry about it ceasing to be maintained.

Oh wow, that’s fantastic news!!!
