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/AF storage systems.
