Backup via WebDAV

Hi all,
is there a way to backup an OwnCloud server via WebDAV. We have many files on OwnCloud but no way to connect the server except the owncloud desktop connector on windows an WebDAV. I`m looking for a tool to connect via WebDAV and copy all files.
Thank your for your help!

I’d say no. With WebDAV, you can access the files of any single user, but not all users.

You could create a special backup user, and all users share their tree with him. Then you can download this with any WebDAV client. But no clue whether this really works.
