Thin Image workflow

Thin Image stores snapshots in a Virtual Storage Platform family (VSP family) storage system.

Creating a Thin Image pair changes the status to "PAIR" and stores snapshot data. You can use Thin Image to store a maximum of 1,024 snapshots of data.

Updating the P-VOL first copies the differential data as snapshot data in pool volumes (pool-VOL) then updates the data. Snapshot data is a copy of differential data in Thin Image P-VOLs. If your storage system experiences a data storage failure, you can restore the data using the snapshot data in the pool.

Splitting a Thin Image pair saves a snapshot and stops the copying of replaced data in the pool.

The following figure illustrates the Thin Image workflow.

You can use snapshot data in open-system volumes.
