Backup (Advanced Copy)
The Advanced Copy function (high-speed copying function) enables data backup (data replication) at any point
without stopping business operations.
For an ETERNUS DX
backup operation, data can be replicated without placing a load on the business server.
Large amounts of data can be replicated by coordinating the timing of business access so data protection
measures can be applied separately from those of 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, 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.

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).
A copy cannot be executed if another function is running in the storage system or the target volume. For details
on the functions that can be executed simultaneously, refer to "
Combinations of Functions That Are Available for
Simultaneous Executions" (page 325).
