I'm trying to sell the use of gzip instead of compress in our department. One issue I'm having (which is a showstopper) is that I lose the ownership when gzipping and gunzipping, though it's mentioned all over the web that files are supposed to keep ownership.

Example:
-rwxrwxrwx 1 ms32345 staff 2847 May 01 09:14 Do_Peyton_pd_Queries.ss

gzip -9f Do_Peyton_pd_Queries.ss

-rwxrwxrwx 1 ad87398 staff 1370 May 01 09:14 Do_Peyton_pd_Queries.ss.gz

Is there something I'm missing? We need to keep ownership for auditing purposes.
