Hi again,
I just had a second thought:

So maybe dh-autoreconf isn't the right place for that anyways.
Maybe it needs a new package called e.g. dh-backup-and-restore which
provides dh_drop_files (backups and deletes files), dh_backup_files
(just backs up files) and dh_restore_files (restores a backed up
files).
Those programs could read debian/drop_files and debian/backup_files as
file lists and copy them away, maybe into debian/backed_up_files/.
Copy and write also would be nice, but somehow sounds like being less
KISS than I'd prefer.
Regards, Axel
