Why does Nextloud full sync run intermittently?

Question

ownCloud/Nextcloud

There is a Nextloud server and a PC on which photos are stored. Periodically, a full synchronization starts on the PC, all folders are cleared, and stupid pumping from the server begins, which takes a lot of time.
It should be noted that the files after the end of synchronization are all in place. There are no errors in the logs, just info that the synchronization with the PC is taking place.
The only thing that comes to my mind is that the system (Win10) and the Nextloud client are installed on the SSD, and the photos are stored on an ordinary HDD (Hitachi 2 TB) and at the time of startup the system does not see the HDD for some time. Sometimes BSODs crash for various reasons.
Does anyone have any thoughts or experienced something similar?

Answer 2

Nextcloud does not work on stock Windows. To make it work on Windows, install Nextcloud VM (Virtual Machine). Read more here - https://www.hanssonit.se/nextcloud-vm/
