Reinstalling Owncloud client

Good morning
Due to a problem with my macOS computer, I had to reinstall my entire operating system. So I am now on macOS 14.5

I also reinstalled ownCloud-5.2.1.13040-x86_64

Regarding usage, I used Owncloud to make backups from my external hard drive to my Owncloud web server 10.14.0.3

Knowing that I reinstalled everything from my computer, I wanted to know if it would be possible to resume the installation without having to create a web server account? Because otherwise, that would mean that I would have to replace everything on my Web server, and therefore it would not be strong enough in terms of storage capacity.

I don’t know if I expressed myself correctly.

I want to continue transferring all changes made in the SSD folder to tatane → files
