When running

rsync -Paz /home/sbird "/run/media/sbird/My Passport/sbird"

As told by someone, I run into a ran out of storage error midway. Why is this? My disk usage is about 385 GiB for my home folder, and there is at least 800 GiB of space in the external SSD (which already has stuff like photos and documents). Does rsync make doubly copies of it or something? That would be kind of silly. Or is it some other issue?

Note that the SSD is from a reputable brand (Western Digital) so it is unlikely that it is reporting a fake amount of storage.

    Idk if rsync traverses symlinks and filesystems by default,

    From the man page:

    Beginning with rsync 3.0.0, rsync always sends these implied directories as real directories in the file list, even if a path element is really a symlink on the sending side. This prevents some really unexpected behaviors when copying the full path of a file that you didn’t realize had a symlink in its path.

    That means, if you’re transferring the file ~/foo/bar/file.txt, where ~/foo/bar/ is a symlink to ~/foo/baz, the baz directory will essentially be duplicated and end up as the real directory /SSD/foo/bar and /SSD/foo/baz.
