The window for those should be pretty small though thanks to
--delay-updates, shouldn't it? However some seem to be hitting on every
sync. Maybe my upstream (gwdg.de) isn't using --delay-updates.
I just noticed there is another Tier 1 in .de by leaseweb, I'll try that
one instead.

I noticed the recommended options have changed and just adapted them.
Besides --copy-links, the previous exclude for dot-files seems to be no
longer recommended as well.
It now synced without errors - well, except

which of course isn't surprising, since deletions are skipped when there
is an error like the symlink problem... And that has been there for a
while, so outdated files probably haven't been deleted in the last few
