Dell EMC AX4-5 manual Snapshot Management, SAN Copy

Snapshot Management

Snapshot Management captures images of a virtual disk and retains the image independently of subsequent changes to the files. The images can be used to share virtual disks with another system without affecting the contents of the source virtual disk. Snapshot Management creates copies of either virtual disks or snapshots. Snapshots are virtual copies that create an image of the source virtual disk at the time the snapshot was created. This snapshot is retained independently of subsequent changes to the source virtual disk. You can use snapshots to facilitate backups or to allow multiple hosts to access data without affecting the contents of the source virtual disk.

WARNING: To avoid data corruption, do not access a snapshot from the same node as its source.

SAN Copy

SAN Copy allows you to move data between storage systems without using host processor cycles or LAN bandwidth. It can be used in conjunction with SnapView™ or MirrorView and is managed from within Navisphere Manager.

Navishphere Manager

Optionally, you can also upgrade Navisphere Express to EMC Navisphere® Manager—a centralized storage management application used to configure Dell/EMC storage systems.

EMC Navisphere Manager adds the support for EMC MirrorView, an optional software that enables synchronous or asynchronous mirroring between two storage systems.

MirrorView

MirrorView automatically duplicates primary storage system data from a cluster or stand-alone system to a secondary storage system. It can be used in conjunction with SnapView and is managed from within Navisphere Manager.
