Advanced Copy

The Advanced Copy functions allows the ETERNUS DX60/DX80/DX90 to carry out high-speed
data copying operations on its own, with no need to draw on server resources.
The Advanced Copy functions of the ETERNUS DX60/DX80/DX90 have the following uses:
• Data snapshots via GUI or CLI commands
• Fast data copies with ETERNUS SF Express
• Data backup in a live data environment using the Microsoft® Windows Server® Volume
Shadow Copy Service function (hereafter referred to as "VSS") with VSS-compatible backup
software
To use the Advanced Copy functions in a VSS environment, the "ETERNUS VSS Hardware
Provider" software must be downloaded and installed on the server. For details of "ETERNUS
VSS Hardware Provider" and how to install it, refer to the following web-site:
