## 5.8 Copy Services 

The IBM Spectrum Virtualize copy services and volumes copy operations are based on the IBM FlashCopy function. In its basic mode, the function creates copies of content on a source volume to a target volume. Any data that existed on the target volume is lost and is replaced by the copied data. 

More advanced functions allow FlashCopy operations to occur on multiple source and target volumes. Management operations are coordinated to provide a common, single point-in-time for copying target volumes from their respective source volumes. This technique creates a consistent copy of data that spans multiple volumes. 

The IBM SAN Volume Controller Copy Services menu offers the following operations in the GUI (Figure 5-41): 

GLYPH<SM590000> FlashCopy 

GLYPH<SM590000> Consistency Groups 

GLYPH<SM590000> FlashCopy Mappings 

GLYPH<SM590000> Remote Copy 

GLYPH<SM590000> Partnerships

Because the Copy Services are one of the most important features for resiliency solutions, study the additional technical details in Chapter 11, “Advanced Copy Services” on page 459. 

## 5.9 Access 

The access menu in the GUI maintains who can log in to the system, defines the access rights for the user, and tracks what has been done by each privileged user to the system. It is logically split into two categories: 

GLYPH<SM590000> Users 

GLYPH<SM590000> Audit Log 

This section explains how to create, modify, or remove users, and how to see records in the audit log.
