Syncthing is an open source continuous file synchronization program. It synchronizes files between two or more computers in real time, safely protected from prying eyes. Your data is your data alone and you deserve to choose where it is stored, whether it is shared with some third party, and how it’s transmitted over the internet.

A great tool ! I’m glad I now can install it on my QNAP. Unfortunately, the upgrade from the former version (1.23) was tedious, because this removes all previous settings. Plus this was instable at first. Once I’ve reboot the QNAP device, and setup again the synchronization pairs, and after the many hours of re-synchronization, this is again up, smooth and great.

how to know which version is for which QNAP
i have a Intel Atom 1.8GHz Dual-core TS-259 pro+ … i suppose it will be TS-NASX86

This app works great and does what it is supposed to do.
The is one thing that is missing in the description is that one has to reboot the NAS to get it working. At least for me the user ‘syncthing’ wasn’t created after the installtion but only after the reboot.

there will be major change in next release on user management
Willem Staaf –
After this update it is not working anymore.

Hi, I’m getting the helpful message “The installation package is incompatible. Use the compatible package.”
Device is a TS-431XeU with the “AnnapurnaLabs Alpine AL314 32-bit ARM® Cortex-A15 4-core 1.7GHz processor”
I expected the “TS-NASARM_64” download was going to be the closets but tried them all.
Any ideas? Does this need a ARM 32 bit package?

Dozens of “permission denied” errors and all local folders STOPPED after upgrading the QNAP .qpkg from SyncThing_1.27.1_x86_64 to SyncThing_1.27.9_x86_64. QNAP is TS-253D running QTS TS-X53D_20240605-4.5.4.2790.
Adding the (new?) syncthing user to the admin group and restarting syncthing did not fix the problem. Shared folder permissions shows syncthing having read/write access to all synced folders. All OK after downgrading to SyncThing_1.27.1_x86_64, which runs as admin.

Love this package … however … stopped working after the .7 patch revision. Getting permissions problems with .stignore and .stfolder on startup.
Tried everything to get the permissions working … to no avail thus far. Had been working for years until this patch ….

Tried to install any version (but x86) of Syncthing/SyncthingR but none of them worked on my QNAP TS-431P2 with Alpine AL314 CPU and 8GB RAM. Every Package is incompatible. Which one should I use? Thanks for the help.
Samuel BRUYERE –
Very great job !
Ps : How to run as root ?
