# fast compression of the big postgresql backup file      #
# we'll take advantage of the multi processor machine     #
# to speedup compression process !                        #
#                                                         #
# reqirement : apt-get install pigz (ubuntu/debian like)  #

# input parameter1 = <entire folder to compress>
# input parameter2 = $CPU_NO
# output parameter = <archive name>.tar.gz - file which will be created


tar -cf <entire folder to compress> | pigz -9 -p <$CPU_NO>  >  <archive name>.tar.gz

# example : 
# tar -cf /tmp/db-public.23122015.backup | pigz -9 -p 16 > /ssd/backups/archives/db-public.23122015.tar.gz
