6.2 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 Disk storage system.
For the ETERNUS DX Disk storage system backup operation, data can be replicated without taking server
resources. 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.
The following figure shows an example of an Advanced Copy operation using ETERNUS SF AdvancedCopy
Manager.
