Dell PowerStore Protecting Your Data

Using clones to access read-only snapshots from hosts

Mapping and unmapping block snapshots to hosts is not supported in PowerStore. To allow a connected host to access a snapshot, create a thin clone of the snapshot and map it to a host. After creating the thin clone, you can use the refresh operation to update the thin clone from different snapshots. For more information, see Refresh a storage resource.

File snapshots can be mounted on hosts either directly (to allow read-only access) or by creating a thin clone (to allow read-write access). To mount the file system directly, the snapshots can be exported as NFS export or SMB share.

You can export snapshots using one of the following access types:

• Protocol - The snapshot is exported with a new share name.
• .snapshot - You can see the snapshot on Unix/Linux under the .snapshot directory of the file system, and on Windows, by right-clicking the file system and selecting the Previous Version option.
