Many companies have minimized the use of tape automation in their IT infrastructure by deploying duplication storage for backup and operation recovery. Dell PPDD deduplication storage systems are the market leaders in this category. In general, operational recovery includes retention periods from a few weeks to several months, however, the system can retain records for up to 70 years. In addition, PPDD systems continue to revolutionize backup and archive data needs by offering Cloud Tier capabilities. This allows users to securely store retention copies in the cloud, while reducing overall storage costs and freeing up valuable space on Active Tiers. By consolidating backup and archive data in combination with Cloud Tier capabilities, a PPDD system optimizes storage requirements resulting in a secure and cost-effective alternative, highly efficient for network-based replication to DR sites.
All PPDD systems, regardless of their retention requirements, present a single file system across all storage available on both Active Tier and Cloud Tier, simplifying system administration. This single file system can be completely or partially exposed as CIFS shares (for archiving applications), NFS mount points (for Unix/Linux), VTL (for open systems), IBM I, and/or through advanced integration with DDBoost (for Avamar, NetWorker, PPDM, Greenplum, Symantec NetBackup, Symantec Backup Exec, Oracle RMAN, Veeam Backup, and Quest vRanger).
The Data Domain system is protected by Data Domain RAID-6 functionality to prevent simultaneous disk failures while maintaining availability. Additionally, the system is protected by the Data Domain Invulnerability Architecture, providing the industry best defense against data integrity issues. In line read and write verification protects against and automatically recovers from data integrity issues during data ingest. Continuous fault detection and self-healing features protect data through its lifecycle on all Data Domain systems. For more information, see Data Domain Invulnerability Architecture.
