Chapter 5 Functional and Operational Characteristics
5.7
Copy Solution Features and Functions
The WMS100 subsystem provides features and functions which allow you to maintain remote
and subsystem internal copies of all user data on the WMS100 storage subsystem for data
backup or duplication. These features include:
ShadowImage In-System Replication Functions
Copy-On-Write Snapshot Functions
NAS Backup Restore Modular Function
NAS SyncImage Modular Function
5.7.1
ShadowImage In-System Replication Function
The Hitachi Data Systems ShadowImage In-System Replication function enables you to
maintain subsystem-internal copies of all user data on the WMS100 storage subsystem for
purposes such as data backup or duplication. The duplicated volumes are created within the
same WMS100 subsystem as the primary volume.
ShadowImage In-System Replication operations are non-disruptive and allow the primary
(main) volume of each volume pair to remain online to all hosts for both read and write I/O
operations. Once established, ShadowImage In-System Replication operations continue
unattended to provide asynchronous internal data backup. Usability is further enhanced
through a resynchronization capability that reduces data duplication requirements and
backup time, thereby increasing user productivity.
5.7.2
Copy-On-Write Snapshot Function
The Hitachi Copy-On-Write Snapshot feature enables you to maintain a logical copy of logical
units (volumes) at a point in time between the disk array subsystems.
5.7.3
NAS Backup Restore Modular Function
The NAS Backup Restore Modular function protects data that is shared in the NAS Modular
system. The NAS Backup Restore Modular function provides the following functions to
protect data:
Snapshot Function
Backup Restore Function
5.7.4
NAS SyncImage Modular Function
The NAS SyncImage Modular function creates a snapshot which enables data to recover to
the state that existed, prior to changes. This data can be recovered even when file system
data shared in the NAS Modular system was accidentally changed.
