  • Page 39: Chapter 1: Introduction

    Introduction The Data Domain DD400 series of restorers are disk-based recovery appliances. A restorer makes backup data available with the performance and reliability of disks at a cost competitive with tape-based storage. Data integrity is assured with multiple levels of data checking and repair.

  • Page 40: Dd400 Restorer Models

    Immediately, data verification processes begin that follow the data for as long as it is on the restorer. In the file system, Data Domain OS Global Compression™ algorithms prepare the data for storage. Data is then sent to the disk RAID subsystem. The algorithms constantly adjust the use of storage as the restorer receives new data from backup servers.

  • Page 41: Data Integrity

    When writing to disk, the Data Domain OS creates and stores self-describing metadata for all • data received. After writing the data to disk, the Data Domain OS then creates metadata from the data on the disk and compares it to the original metadata.

  • Page 42: Restore Operations

    Replicator The Data Domain OS Replicator product sets up and manages the replication of backup data between two restorers. After replication is started, the originator automatically sends any new backup data to the replica.
