2. Basic Functions

Backup (Advanced Copy)

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.

(System down time)
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
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
