You sent your question to the gzip mailing list, but gzip wasn't 
responsible for your data loss.  While I feel sorry for your loss, 
there's not much I can do beyond pointing you to this coreutils FAQ:

https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#I-used-rm-to-remove-a-file_002e-How-can-I-get-it-back-now_003f

Meanwhile, I'm tagging this thread so that the bug-tracker doesn't keep 
it open as a gzip bug.
