I integrated an external FTP-Server to migrate the data from FTP to Nextcloud. It’s 10300 files, 2900 folders and almost 32 GB of data. During that operation Nextloud logs the following errors:
Update: I figured out my problem: It stopped on some files with the German letter ß in the file name. I tried to rename it with Filezilla on the source, logged in by SFTP. It wasn’t possible. The error was that the source file didn’t exist. After I logged in with unsecured FTP I was able to change the filename. It seems to be a problem with special characters and SFTP. But it was not every file with ß inside, only some of them.

Nextcloud version: 18.0.4
Operating system and version: unknown (managed server)
Apache or nginx version: unknown (managed server)
PHP version: 7.4
The issue you are facing:
Copying a large amount of data from SFTP (as external storage) to Nextcloud.
Is this the first time you’ve seen this error? Y (but also first time I did this)
Steps to replicate it:
- Implement SFTP server with a lot of data as external storage
- Copy them inside Nextcloud from SFTP to Nextcloud
