DynamicSnapVolume (DSV)
NEC's DynamicSnapVolume (DSV) storage software enables cost-effective backups without disrupting businesses by creating snapshots of logical disks.

Snapshot Creation
Quickly create snapshots of logical disks in the storage system using DynamicSnapVolume. Create a replication of the master volume (the snapshots) instantaneously, up to a maximum of 16 generations of snapshots on one master volume.
Snapshots Deletion
Delete any generations of unnecessary snapshots, maximizing disk utilization.
Snapshot Restoration
Restore any generation of snapshot volumes into the master volume.
Generation Management
Manage multiple snapshots generations by using their creation times. Use the newest generation of snapshots constantly without the need for the names of the logical disks.
Efficient and Simple Backup Operations
Replicate volumes at a low cost, with no impact on server performance. The snapshot images on the disk use less space than on the master volumes. Create and restore snapshot volumes using StorageManager and CLI.
