Nextcloud client high disk write when syncing

[tianer2820]

I’m using the sync client on Ubuntu 22.04 to sync an NTFS drive (with ~300GB file) to the server.

Every time the sync starts, I notice a several-minute period where the disk write speed goes to ~80MB/s while the network upload/download remains very low, and the client says “syncing with local folders”.

I’m curious about what is happening during this period. I didn’t see any large log files or databases popping up, and since the download speed is near zero, it should not be writing downloaded files to disk. And if I’m using a flash drive, will this shorten the disk life due to the large volume of writes?

every time the client starts/returns from sleep there is a “full scan” of sync folders resulting in very verbose logging - https://github.com/nextcloud/desktop/issues/5302 unfortunately the devs are not willing to reduce the logs at the moment
