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.

Copy-only backup do 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.
I think the development team uses the most recent version for some test. COPY_ONLY option is OK.
Yes, it’s copy_only
@see also http://www.mssqltips.com/sqlservertip/1075/copyonly-backups-with-sql-server/
It is a live database, even cp-only full backup will produce unpleased user experiences.
I think the “you need a full backup” is confusing, it might mean the full copy of the database regardless the backup approach.
transaction log backup will min impact live db and plus daily full and differential, you can restore the FULL database to dev.
COPY_ONLY is correct @see also http://mitchespitch.com/2012/05/02/the-copy-only-backup-what-is-it-and-why-use-it/
I would go with COPY_ONLY Option.
The Question demands an adhoc backup to be taken for refreshing the DEV Server.
It is a FULL backup option but without affecting the existing backup sets.

transaction log is not an option. copy_only is.
