Fujitsu ETERNUS DX60 S3 - Backup (Advanced Copy); Figure 3.16 Example of Advanced Copy

3.7 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.
