SnapVX snapshots protect applications without the use of target volumes to capture change data (deltas). Snapshot deltas are automatically maintained at the storage back end using pointers to the relevant point-in-time images. Resource sharing and data deduplication automatically take advantage of this design to provide cache, capacity, and performance benefits.

Compressed source data remains compressed when becoming snapshot delta. Uncompressed source data might become compressed as it becomes snapshot delta or as it becomes less active. Read activity through linked targets might prevent an uncompressed delta from being compressed or cause compressed snapshot deltas to be uncompressed. Snapshot deltas are available for deduplication.

Enabling data reduction on a linked target only affects data owned by the linked target. Data on linked targets and clones is available for deduplication.
