It makes sense we can't copy symlinks into cloud providers.
Is it possible to, on the cloud, create a text file where the symlink would be and put the destination of the symlink as the contents of the text file?
So if /file is a symlink to /some/other/file then in the cloud provider /file would be a text file that contains /some/other/file.
This way vital information about files, especially for system backups, is still preserved.
