RealTimeSync doesn't work both ways

[Falk]

Hey there,

I am running two ubuntu-machines. On both machines I need to have the same content up to date. So If I change it on one it has to change on the other too. As a kind of bridge I am using my wlan-router sporting a NAS-USB-Stick available for me through internet.

What I did was to create a synchronisation of the local folder and the NAS. The synchronisation works just fine. I "batched" it and started the RealTimeSync with the batch.

When I start the RealTimeSync it synchronizes in both ways on each machine. But than something odd hapens. If I change something on machine A it synchronizes to the NAS. In my thoughts machine B should now synchronize from NAS to itself, but it doesnt. Same problem when I change something on B. It sends the change to the NAS but A doesnt "sense" the change on the NAS.

Interesting too. I changed something on A, therefore it changed on the NAS. If I change something different on B the change triggered from A is now changed on B too. Of course the change from B only gets to NAS but not to A .... until there is something changed.

Any suggestions?

It sounds like the router-NAS does not (properly) support directory monitoring.
This is not unlikely, as it is not a full-fletched NAS.
Read the third bullet of the RTS limitations.

If you are using Windows, you can get around this by sharing the folders you need synced. Computer A shares the folders, computer B maps them or accesses them via hostname, you sync A<->B using RTS, and then also set up computer A to use RTS and sync between it and the NAS for backup purposes

I have the same problem. I understand there could be a problem with reporting changes to system from a remote location, but is there any way to fix this or apply some workaround?

I try to synchronize a vault for Obsidian (Linux Mint machine) with my NAS (SMB share hosted on TrueNAS Scale home server), so I can use Obsidian on all my devices with all my notes being up to date. I set "2 way synchronization" with additional versioning in FreeFileSync and saved it as *.ffs_batch. Then I passed this file to RealTimeSync and clicked "Start" button. When I change someting on my Linux Mint machine, it's being synchronized with my NAS within a time set in RTS (RealTimeSync), but when I change something on my NAS it doesn't always reflect on my Linux Mint PC (when I create a file on NAS it never synchronize to PC, but when I delete a file, then SOMETIMES it does synchronize).

Here's my *.ffs_batch file:

BTW: isn't RTS producing any logs while running? I've found logs for FFS, but not for RTS itself. I was getting some "Error" before and wasn't able to debug it - when I hover mouse pointer over RST icon it only says "Error", which isn't very useful.
