Example of Differential Backup Settings
This section describes the RAID configuration settings by using the settings for differential backing up with
SnapOPC+ as an example.
In the ETERNUS DX, the differential copy function (SnapOPC+) can be used without needing any optional
software. Mounting the copy destination volume on the server allows the past data to be seen as a drive, and
the past data can be easily restored with copy & paste from the assigned drive.
