Restore Architecture and Data Flow

Restores are accomplished through the management console. Internally, Catalogic DPX uses LUN mapping and Storage vMotion to provide either an Instant or Full restore.

• For Instant restore of a VM or VMDK, Catalogic DPX creates a LUN on storage systems from the backup snapshot you select as the restore source. Catalogic DPX then maps the LUN to the ESX server that hosts the VM restore destination, creates a temporary datastore containing an RDM VMDK, then attaches the RDM VMDK to the VM restore target. That completes an Instant restore, and the VMDK is available for use through iSCSI LUN mapping.

• A Full restore of a VM or VMDK includes the same steps as Instant restore and then uses Storage vMotion to migrate data from one or more RDM VMDKs on the temporary datastore to flat VMDKs on a production datastore.
