Backup (Advanced Copy)
The Advanced Copy function (high-speed copying function) enables data backup (data replication) at any point
without stopping the operations of the ETERNUS DX.
For an ETERNUS DX backup operation, data can be replicated without placing a load on the business server. The
replication process for large amounts of data can be performed by controlling the timing and business access so
that data protection can be considered separate from operation processes.
An example of an Advanced Copy operation using ETERNUS SF AdvancedCopy Manager is shown below.

There are two types of Advanced Copy: a local copy that is performed within a single ETERNUS DX and a remote
copy that is performed between multiple ETERNUS DX storage systems.
Local copy functions include One Point Copy (OPC), QuickOPC, SnapOPC, , and Equivalent Copy (EC),
and remote copy functions include Remote Equivalent Copy (REC).
The following table shows ETERNUS related software for controlling the Advanced Copy function.

The copy functions can be used without optional soft-
ware.
ETERNUS SF AdvancedCopy Manager
ETERNUS SF AdvancedCopy Manager supports various
OSs and ISV applications, and enables the use of all
the Advanced Copy functions. This software can also
be used for backups that interoperate with Oracle, SQL
Server, Exchange Server, or Symfoware Server without
stopping operations.

A copy is executed for each LUN. With ETERNUS SF AdvancedCopy Manager, a copy can also be executed for each
logical disk (which is called a partition or a volume depending on the OS).
