Hi,

I’ve created a “Send Only” folder in a Windows 10 machine. I’ve shared it as a “Receive Only” folder in an Ubuntu 18.04 machine. Both folders are in external USB drives both formatted in NTFS.

Files have been copied correctly and Global and Local States are the same. But in the Receive Only folder in Ubuntu I see all the files and folders listed as “Locally Changed Items” (119.334 files + 3.697 folders = 123.031 items), but with 0 Bytes of changes. I guess that it is related to some kind of different permissions, ownership or some limitation using ntfs in ubuntu with syncthing.

Using “Revert Local Changes” starts a scan, but it ends on the same place. Any ideas?

Thanks!

PS: I’m gonna donate to the project for sure. I’ve been using it for a week and besides this (small) issue, it worked so great so far!

Hi, I have just installed Syncthing to sync files between a Raspberry PI 3b+ and a Windows PC and it works brilliantly.

But once I reboot the Raspberry Pi I’m struggling to restart Syncthing without double clicking the executable each time before opening the GUI.

Is there a command that I can use in terminal?

What I would really like to do is add it to /home/pi/.config/lxsession/LXDE-pi/autostart

Sorry if this is covered elsewhere but I couldn’t find anything.

Thanks for your help,

I noticed that we rotate logfiles on every startup, not just if the file grows too large. Is that intentional? To me that behaviour is unexpected.

Hi,

I’m using Syncthing to save files from my family’s PCs and smartphones to my NAS, with staggered file versioning (which works very well!!). So if somebody makes a mistake (deletes a file, changes it by mistake…), previous versions are saved apart in .stversions folder on the NAS. People in my family today don’t have a direct access into the NAS (debian-based, actually OpenMediaVault).

I wonder how I can give easy access to the .stversions subfolder on the NAS so that they can restore some previous files or folders, either at home from the LAN or outside on internet. Can Syncthing do it (I guess not, but asking never hurts)? Should I setup something line Nextcloud for this? Do you have suggestion for this? Thank you!

I have an Android phone with 64GB of storage and I take a lot of pictures and video (parent young kids). Whenever my phone storage space starts getting full, I transfer the files to my NAS server (also backup on Google Photos). Rather than manually transferring the files to my NAS, I figure I give ST a try. I setup Syncthing on my Android phone and selected my Camera folder. It was set to “Send Only”. I then shared the folder to my desktop computer and starting syncing to my NAS. ST then started deleting all of my photos and videos that were not on my phone! Luckily, I have another backup of this data on an external drive. I disabled ST and restored my data to the NAS.

I did not expect ST to delete data on my NAS, since the Android folder share was setup as “Send Only”. Is it possible to use ST as a backup solution in my situation?

Damn … I wish i knew how to use this thing! Situation is that an ‘initial’ sync, not yet paired with anything, flagged up well over a 1000 ‘local changes’?? Not yet understanding why or how this could happen as the folder in question is receive only and i had no other systems attached as shares, I elected to ‘revert local changes’ expecting the situation to revert to as it was prior to any sync, ie just undo anything you havent yet done. Oh no … was i wrong. The ‘reverted changes’ proceeded to wipe my disk contents, verifiable from the log. Now then … just which bit of all this, what i consider to be a very dangerous package, have i not understoodand just what were the ‘local changes’ which were identified. Nothing had changed my files which were an imported disk from the host system after it had copied off its files to a larger disk. I am loathe to make any further use until i understand a bit more.

Due to the current activities and RC upgrades to v1.4.0-rc.1-x, I ask to discuss the usual handling of version stages.

I am not a software developer and you are much bigger and better experts than me. I myself come more from the mechanical engineering, so it’s simple. Nevertheless, I know about the differences between the software development phases alpha, beta and release candidate.

I have been using Syncthing for a long time now and it seems to me that v1.4.0 contains some major changes compared to v1.3.4 and compared to previous versions less of v1.3.4. Since RC.1 there have been some major problems, so the term “release candidate” means in my opinion is not justified. Also what happened today with the RC.6 shows again that I think we are more in a beta since in a RC phase.

I like to test such software and I am aware of the risks, even if the software is no longer alpha or beta, but already an RC. I don’t have to tell you what “release candidate” means, maybe I’m wrong, but at this stage software is mostly finished and bugs like those in RC.1-6 have been fixed in a beta. So there are only “cosmetic” changes to achieve the final release, here to v1.4.0.

What is your opinion about this?

Continuation of UI is not updating nor saving settings

grafik1919×945 346 KB

I’m still having these problems. This time on a different PC though.

I tried to enable config logging:

grafik1916×916 102 KB

How can i activate config logging, when no config-post is processed by the server?

My guess is that the large number of requests creates I/O activity, which is the bottleneck on a slow computer like this one. Thus the requests don’t get processed as they should. Maybe some mechanism schedules (usually short) read actions higher than write actions like the “config” post. But since there are so many gets constantly fired at the server it won’t ever process the other requests.

A solution could be to throttle the requests fired at the server, if the client detects, that the server is answering slowly. One idea could be to not requests new events or status updates if another request is still pending and only retry after 1 or 2 minutes or so or if the request officially failed.

A fix for this would really be appreciated, as i can not manage my systems with this problem. It’s config hell right now…

Greetings Fred;

I’m experimenting with the REST API, and I managed to successfully subscribe to notifications about the sync local status, specifically when the local machine is syncing files from the network.

However, I can’t find events that notify about remote machines downloading files from the local machine. This is useful not only for reassurance that locally modified files are being synced remotely, but also to know when it’s not a good time to turn off / sleep / disconnect the local machine. The UI does show that remote machines are being synced but doesn’t show whether they’re pulling stuff from the local one or just syncing between each other.

Any ideas? Thanks!

In the not to distant future I plan to release some code open source. They are private projects for now, but I realised it may not be appropriate to use the Syncthing name as they are not official projects?

The code is client only, so only connects to a single Syncthing instance. so I was going to call the projects SyncthingClientCore for the library and SyncthingClientDrive for the first project that uses the library to mount the shared folders as a FUSE mount. I will put a clear message that these are not official (and at the moment they are very alpha) in the README, but I didn’t want to cause any confusion or annoy anyone.

I see this question is asked pretty often and is in FAQ, but I would like to make it a little bit more specific, so to understand whether I should use it for my use-case, or it’s not advisable to.

I have a huge directory which I would like to mirror (The Backup further in the text) to two or three remote servers, one of which I have on my LAN and others on the other locations I have access to. The backup process happens not very often, once a week. With data being just added up. Basically that’s some sort of archive for our team’s work projects, which are also synchronized either via git or Syncthing, or both (more on that later). Those projects contain such file-types as html, css, js, psd, sketch, images and other office type files. The weekly additions is expected to be within 10 GiB in size, and The Backup is cleaned up annually, moving about half of its size to a non-synchronized server with an SSH access (The Archive further in the text), so that we keep only this and last year projects.

The size of The Backup directory is expected to be less than 100 GB, but the number of files is unpredicted. With all that said, I have these questions:

1. Is this design encouraged with Syncthing’s architecture, or is it just a specific use-case I have to test on my own? There’s a Is Syncthing my ideal backup application? section in FAQ, but it barely answers this question. And it looks like a really useful scenario to me, since I want the directory to be synced as I change it, preferably automatically. That looks especially useful with remote hosts, which are less easier to manage.
2. Does the frequency of files changes make any difference to the performance? I would like to use my old home-server (Pi-like performance, Arch Linux with Intel Atom 230 on the board 2 @ 1.6 GHz with 1 GB of RAM, just 150 MB is used right now). As I tested, 1 GB directory with frequent changes works very well. Will it work similarly well while being 100 GB in size and less frequent changes being made, with just 1 GB being added once in a while, in a root of the directory?
3. Will the number of writes to the disk be significant in that case? Having The Backup directory synced is very useful, but if the number of writes is significant (which I assume wears disks a bit quicker, am I correct?), then I should redesign the architecture to move directories from The Backup to The Archive more often, since the latter just lives on a remote server.
4. And for the syncing git thing is a bit of off-topic to my general question, but I put it here as well. I have some projects with git and some are not. If git is strongly discouraged to use with Syncthing, I have to redesign my directories architecture the way Syncthing will do the job only for sans-git projects, which would complicate my system significantly. I tested Syncthing and git with basic markdown notes and haven’t found any issues so far, but that’s not a proper test of this system. In case it’s only me who works with those git-directories, would it still be discouraged to use git? Will it be discouraged, if I work only from one machine and backup the directories with git the aforementioned way, with Folder Type setting set to Receive Only, and push changes from the original machine? If I understand the algorithm correctly, then there’s no difference for my original machine a remote Syncthing directory will mess my current working git directory. I found a thread with very similar question: Sync Large Directory with Raspberry Pi3 (Deadlock?), but it’s almost 3 years, so things could change a little.

I believe that should be of no difference, but for this use-case with The Backup we use macOS and Linux machines only, and Linux machine for The Archive, which may later be switched to FreeBSD.

Thanks.

P.S. The forum forced me to remove the links due to me being a new user, so I left just two, with no links to the documentation that I mentioned in the post.

Hello, all. First time post. LOVE this awesome little bit of coding brilliance. Anyway, I have SyncThing successfully deployed, replicating folders among 4 other different, unrelated PCs back to my server. But I’m stumped on this new one.

The only major difference here is that at the site in question, there are “nested routers,” in other words the ISP’s router (Arris, with a firewall port-forward on the SyncThing configured port to the internal router’s WAN port) connects to the router that feeds the corporate LAN (SonicWall, cross-checked against other working setups), and as such the PC with the folder I need to sync. I’ve triple-checked settings, the “Connections” tab, etc., but the status still shows as “Disconnected.” Are nested routers problematic, or should I look elsewhere?

Thanks for any ideas!

I currently sync between Windows, Linux, MacOS and three android devices. At a high level, I have a folder for syncing Music and another folder for text files (to-dos, shopping lists, contacts, calendars, etc).

I would like to disable syncing on mobile network for Music folder as the files are large but I need the text based files folder to be synced always even on mobile network.

I could not find an easy way to do this and here are couple of approaches I am thinking of, none ideal.

1. Change behavior such that Music folder is updated only when all the phones are on Wifi (it’s getting difficult to manage this)
2. Move Music folder syncing outside of Syncthing but I didn’t find a suitable solution and enable “Wifi only syncing” on that app
3. Manually update the content on devices. Ugh !!

Not sure if this is possible with the current design of Syncthing so I thought I would check.

Hello, I’m running Syncthing from a Docker container by linuxserver on my Pi4. I’ve created on my desktop computer with send only settings and a receive only folder on the Raspberry. After the complete syncronization of the folders on the raspberry I have a lot of Locally changed items appearing. If I press on the red button nothing happens and in the logs I have this error: “Revert: directory is not empty; files within are probably ignored on connected devices only” It’s strange because I haven’t added or modified anything, out of ideas I’ve tried deleting everything on the receive side and after the complete sync happens the same. The issue appears only on folders and not on single files. Any ideas?
