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.
