Package: nextcloud-desktop Version: 3.1.1-2+deb11u1 Severity: important >From time to time, whole directories get erased from the server for no reason. I've seen it happen a few times already, but not early enough to be able to catch logs. So far I've been lucky enough to be able to restore from backups, but it's not something that I can afford to see happen again.
In my case, the client sent a DELETE request for a directory that hadn't been deleted locally. The ~/.local/share/Nextcloud/Documents_sync.log file shows it: 12:27:42||TEMP|INST_REMOVE|Up|1633813324|61620350e2e1d|0|06377550ocptyqgkbgt0|4||204|0|0|||| At the same time, the server log shows the corresponding request: [REDACTED] [17/Oct/2021:14:27:42 +0200] "DELETE /remote.php/dav/files/DetR/Documents/TEMP HTTP/1.1" 204 609 "-" "Mozilla/5.0 (Linux) mirall/3.1.1-2+deb11u1 (Nextcloud)" So obviously, on all other clients using that shared Documents directory, the TEMP directory is deleted. It's still present locally, but there's a discrepancy with the server, and that discrepancy is not always resolved in the right direction: sometimes in the past the directory was restored from the local version and eventually re-uploaded then re-synced to other clients, but other times the local version was deleted too, in which case the directory is completely lost. This is really major, and the fact that it happens "rarely" (although a couple of times a year for me) doesn't make it less grave. For reference the server runs 21.0.0, but I've seen this bug happen with previous versions too, and I don't think the bug is server-side. I'm fully willing to help provide more info if instructed how, but note that the bug is unpredictable to me. It may be relevant that my Documents share is about 500 GB in size, with about 300k files.
