Synology Cloud Sync error at 8TB upload

Hey there Tom - sorry to hear about this.

From what I understand, the setup you are using has the Dropbox folder on a NAS drive.

Dropbox could be presenting this behavior because network file systems do not send messages when files change. When Dropbox first starts it will do a deep file scan and will detect changes and sync them. However, during normal operation, Dropbox waits for "file update events" and only physically connected drives send these events.

The best fix to this problem is simply to move the Dropbox folder to a computer's internal drive. You can use the steps in this Help Center article.   

I strongly recommend choosing a location on the same hard drive as your operating system while making sure its on a supported format as well. Dropbox won't work correctly should the Dropbox folder ever become inaccessible.

In any case, good move to contact synology's support as you mentioned, they might have a better insight on this one. 

If there's anything I can do to help from my end, do let me know and keep me posted on your findings too TomCutting! 

Thank you!

For clarity, the OP isn't referring to the storage of a Dropbox folder on a NAS which is then being synced by the Dropbox client on a computer. Synology has it's own Cloud Sync app that utilizes the Dropbox API for syncing direct from the NAS to Dropbox.

Unfortunately, you'll need to contact Synology directly as only they can support their application.

Hello everybody,

i have a similar problem, and already ascalated to synology development team.  The error in the log files of synology cloud sync app are no connection to api.

I tried out everything, and some randomly file's of different types are not syncing!

I use dropbox from 2009, and with the desktop client program there have been never any eeror's acurred.

With cloud sync i tryed on another nas, bidirect sync, only donload, everything but nothuing helped.  Only when a drag and drop the problem files from my desktop pc (local dropbox storage) true the synology webbased file station.

I understand that they don't give support for tird party apps, but both big company's with great reliability can maybe work together for a trustable stable app.

I have data around 800gig's and you don't see this on small items, i've seen it in the logs, but there are over 100.000 items to sync and the log only displays for 20.000.

Dropbox support asked me to ask a question here, but the big question is, what is the real problem of all this ? When someone can explain and don't give a solution, i have to make a virtual machine with dropbox in it, what will give me a better solution, and then i can use LAN sync feature built in dropbox pc software...

Kind regards

Bart

Hi Tom,

i have the nas fully updated (synology nas), i have used 79% of my dropbox.  The files aren't very big, so wierd that i should have to upgrade, because on a desktop pc it runs fine...

I think i leave it by this because it will be a ping-pong game between synology /dropbox and i understand both of them to be nog responsible for data loss due to 2 same languages with a different accent :-)

Thank you for the reply and have a great day without machine troubles :-)

Did you do any price comparisons between different cloud backup companies (DropBox, Box, OneDrive etc) before making your choice to go with DropBox?  I have about 10TB of Synology NAS data that I would like to be able to Backup, but DropBox costs seems to be prohibitive.

Your thoughts please.
