Hello,As we know in sql 2014 we have inbuilt compress backup feature. So I have 50 GB db size and the backup of this db becomes to 5 GB.Now I need to zip this 5 GB backup and I use 7zip free utility but then zip file is still 4.5 GB.The question is, is this a problem with zipping software? If I buy licensed version can I still reduce the size?or it will not work with licensed version because sql has already compressed the file??Please let me know.Thanks.
