PowerStore snapshots are space efficient. Snapshots consist of pointers to frozen data blocks. Snapshots do not consume space. When you create a thin clone from a snapshot and map it to a host, only new data written to the thin clone consumes additional storage space.
PowerStore snapshots can be taken of volumes that are mapped as LUNs to a Hyper-V environment regardless of content. Volumes, snapshots, and thin clones can be replicated to other PowerStore clusters for DR or archive purposes.
For more information about PowerStore snapshots, thin clones, refreshes, and restores, see the online help in the PowerStore Manager UI.
PowerStore snapshots allow administrators to perform the following actions in Hyper-V environments:
PowerStoreOS 3.5 introduced secure snapshot as an optional setting for volumes and volume groups. The secure snapshot feature provides the following benefits for Microsoft environments:
Note: If you disable secure snapshot for a volume, you must wait until the expiration date before you can delete secure snapshots.
