I've backed up a database on SQL Server 2012 that resulted in a file of 33MB in size. Then, I restored that backup on SQL Server 2016 and created another backup, but this time on SQL Server 2016.
The size of the backup changed from 33MB (SQL Server 2012) to 315MB (SQL Server 2016).
Why such big increase to the size of the backup file on the SQL Server 2016?
Appreciate any help.
