The copy utility is one of the most frequently executed backup and recovery utilities. CPU cycles spent on creation of backup image copies might represent a considerable portion of the total cost of backup and recovery.
If you are creating standard full image copies to back up your database objects, consider switching to the EXCP NO copy engine of CA Quick Copy for DB2 for z/OS.

CA Quick Copy for 18.0 provides a completely rewritten EXCP NO copy engine with the following benefits:
- Reduced CPU time by efficient coding and efficient task synchronization.
- Offloading of up to 50% of the work to zIIP.
- Support for all object types and dataset types (extended format, extended addressability, and stripped VSAM datasets).
