we have decided that it is a time to go through Copr backend data and
clean it up a little. Due to several bugs forgetting to remove backend
data after removing their records from the database, _temporarily_
backing up some folder here and there, etc, we ended up with a lot of
unknown data, that should have been already deleted.
So, we wrote a script  to find data that should be deleted, and we
... haven't deleted it yet. Instead, we put it aside in a case there
were any false-positives by the script. If you want to be extra safe,
I am attaching a list of all of those files, you may check it.
If you find out, that we accidentally want to remove any of your data
that is still being used, please contact us immediately! Otherwise, we
are going to delete it once we are running out of disk space (which
may not take a lot of time)
Thank you for understanding,
