Dell PowerStore Protecting Your Data

Create a thin clone

Thin clones are writable copies of a snapshot, volume, volume group, or file system that can be accessed by a host. Unlike a full clone, a thin clone is a space efficient copy that shares data blocks with its parent object and not a full backup of the original resource. A thin clone can be created directly as a copy of the parent object or using one of its snapshots.

Thin clones retain full read access to the original resource. You can modify the data within the thin clone while preserving the original snapshot.

Using thin clones, you can establish hierarchical points in time to preserve data over different stages of data modifications. If the parent resource is deleted, migrated, or replicated, the thin clone is unaffected.
