Klaus,

Copy actually makes a *copy of the entry to in the Table-of-Contents*, 
which can be styled in various ways BUT ACTUALLY points to the same file.

If you wanted *a physical copy the file* you needed to 'Export' the 
shapefile.

Unless you made a backup you will have lost your data.

On the off chance check to see if a backup of the table exists in the 
directory. Also, if you have not saved the project yet,
*cancel everything without saving* and the changes will not be committed.
