Summary of the issue you are facing:
When adding files and folders to a folder that is being synced, the sync starts, but after a while the client starts to delete files and folders randomly.
Steps to replicate it (hint: details matter!):
- Set up a brand new server via Docker on a mac.
- Install the desktop client
- Choose a folder to be synced
- Copy a bunch of files and folders to the sync folder from another source
- The sync starts and goes for a while
- The client hangs
- The sync restarts after the client is started again
- The client starts randomly deleting files and folders
- There is no possible way to get all files/folders synced to the server
I have tried this for five months in all ways possible. Let the sync go until the client seems done and then copy all the deleted files from the source again, but then they or other files gets deleted. I have tried to go via the web client, but it is too many files so it’s not feasable. I have tried to use the webdav mount and rSync to copy them to the server, but it is so incredibly slow that after a couple of weeks of running I gave up and then only a few hundred files had been copied.
The files that gets copied to the server stays there, but the files there is not necessary visible in the web client and not on other sync clients (phone, computer). The files in the “source” sync folder are deleted randomly and the last test I did today where I copied 5 660 files (8.44 GB) resulted in 7.31 GB on the server and after the client did its random delete 6.77 GB in the “source” sync folder.
I have no other clients running but the single one. The files being deleted has NEVER been deleted or even handled by any person.
It seems to me that the client is fundamentally broken and can’t handle the task at hand.
I have tried this so many times from a fresh install of the server and client that I have lost count. I have reduced the number of initial files from approx 300 000 to now just a few thousand and no luck. The client constantly hangs and randomly deletes files suddenly.
It would be a nice feature to have to be able to tell the client that a sync folder is read only (I know you don’t like this since it defeats the ‘sync’ functionality, but right now it’s completely unusable without this feature and the possibility to force upload).
A nice to have would also be a script that restarts the client when it hangs. I have written one myself that runs with LaunchAgent and an AppleScript:
-- ~/Scripts/watchNextcloud.scpt
-- Startar Nextcloud om den inte körs och dödar den bara om den slutat svara
property gracePeriod : 10 -- sekunder att vänta efter "quit"
property pingTimeout : 3 -- sekunder att vänta på svar från appen
-- ▸ Pingar Nextcloud med en enkel Apple-event
on appResponding()
try
with timeout of pingTimeout seconds
tell application "Nextcloud" to get id of it -- billigt "ping"
end timeout
return true
on error errMsg number errNum
-- -1712 = timeout → appen svarade inte i tid
-- alla andra fel räknas också som ”inte svarar”
return false
end try
end appResponding
on run
tell application "System Events"
------------------------------------------------------------
-- 1. Finns processen?
------------------------------------------------------------
if exists application process "Nextcloud" then
--------------------------------------------------------
-- 2. Svarar den?
--------------------------------------------------------
if not my appResponding() then
-- Försök vänligt först …
try
tell application "Nextcloud" to quit
end try
repeat with i from 1 to gracePeriod
delay 1
if not (exists application process "Nextcloud") then exit repeat
end repeat
-- … och tvinga ned om den fortfarande lever
if (exists application process "Nextcloud") then
do shell script "/usr/bin/killall -9 Nextcloud"
delay 2
end if
end if
end if
------------------------------------------------------------
-- 3. Starta om om den inte körs
------------------------------------------------------------
if not (exists application process "Nextcloud") then
tell application "Nextcloud" to activate
end if
end tell
end run

Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
There are no entries in the log of delete. The full nexcloud.log is 112 MB, so I will not paste it here.
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
Not applicable
Web server / Reverse Proxy
The output of your Apache/nginx/system log in /var/log/____:
I have no logs in NPM
Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):
