copy external folder into internal folder

Hi,

I have a Nextcloud v34.0.0 instance.

I have an external ftp storage called vault that contains around 70 GB of data.

I want to move the files from the external storage to my internal folder, for example, the my_files folder.

I want to know how I can reliably copy my files from my external storage to this local folder.

I use server-side encryption, and the ftp storage is managed by Nextcloud from the beginning.

With the server-side encryption, I’d go through the official webdav interface. You can try directly a client with webdav that can move files without downloading them (windows: winscp). Is this a fast connection between the server and the ftp storage?

I haven’t tried this recently, but copying a few files directly like this worked ok if the transfer speed is high (I used SFTP at the time and also a few GB of data). But speed between server and storage >100 Mbit/s. And I didn’t use the server-side encryption…
