Issue:

How take a backup that does not affect the night differentiation backups etc ?

Solution:

Take a full backup and select copy-only backup in general.

In this example, a copy-only backup of the test database is backed up to disk at the default backup location.

1. In Object Explorer, connect to an instance of the SQL Server Database Engine and then expand that instance.
2. Expand Databases, right-click test, point to Tasks, and then select Back Up….
3. On the General page in the Source section, check the Copy-only backup checkbox.
4. Select OK.
