Hi when I perform the tar it has tarred but after removing the original
file.i mistakanley pressed the previous command to tar then it has
overriden and size showed 45.so pls help me to extract the original or
tarred file.
#tar -cvzf server.log.tar.gz server.log
#ls -ltr-> it showed size 270mb server.log.tar.gz
And then mistakenly I pressed previous command

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.
