I have SQL Server 2012 and doing backups several times in day. Everytime I make backup, size of bak file grows even changes has been very small since last backup. Bak file size have growed so fast that hard drive capacity has been reached.
Why? What information is added to the bak file? Is it backuping every single transaction?
How to optimize so that bak file consist only the current status of tables and contents?
