A hardware function [Advanced Copy Function] of ETERNUS disk storage systems is used to back up data quickly. The Advanced Copy Function provides fast data copy independent of data volume, and can maintain a fixed backup time even if the amount of data to be backed up increases.
This function can drastically reduce the duration for which a transaction must be stopped to perform backup. If a transaction uses a database or a general file system, the time that transaction is stopped is still significantly reduced.
Using the remote copy function of ETERNUS disk storage systems, it is also possible to back up to ETERNUS disk storage systems at remote locations.
