Hi Guixers,

thanks for Your advice Ludo and all other Guixers,

for Your information (first time of using gc):

After using Guix System for 6 month I did a:
"guix gc"

It collected about 50 GB and deleted that.
(I wanted to do that to get to know how it collects without deleting generations)
Than I deleted all generations
I did a "guix gc" again
and it deleted approx 40 GB again.

After that I did a
guix pull,
guix package -u,
sudo guix system reconfigure /etc/config.scm

and it downloaded approx 2,2 GB of packages.

The result of that is, that in future I will do a
"guix gc -F20G"
in order not to delete too much and later to redownload and rebuild them.

I agree that 'guix gc' deletes too much, but it's probably not
dangerous. You will just see some downloads and builds repeated when
reconfiguring later.

Indeed, it’s not dangerous, and I don’t think the manual suggests that.

To avoid collecting things just to redownload/rebuild them later, I
usually ask ‘guix gc’ to free up some amount of space, as in:

   guix gc -F20G

That ensures 20G (more or less) are available on my disk and doesn’t try
to collect more than that.
