You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage
area network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D). A transaction log of 10 GB is located on a
dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between
09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and
15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the
database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every
two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
On Wednesday at 10:00 hours, the development team requests you to refresh the database on a development
server by using the most recent version.
You need to perform a full database backup that will be restored on the development server.

Explanation:
COPY_ONLY specifies that the backup is a copy-only backup, which does not affect the normal sequence of
backups. A copy-only backup is created independently of your regularly scheduled, conventional backups. A
copy-only backup does not affect your overall backup and restore procedures for the database.References:
