4. Confidential4 What is a Data Domain Restorer (DDR)? Data Domain is a Backup Device  Integrates into Existing Backup Software  Compression Engine  Replication Engine  Reliable

5. Confidential5 What is a Data Domain Restorer (DDR)? A (Fileserver or VTL) for backup images & “tape” archives  tar/cpio/etc. files (including images from Symantec, Legato, …)  NDMP dump images  Database dumps  Copies of critical files  Network (gig-E) attached A very efficient compression engine  Avoid writing previously compressed data  Let the DDR do the compression Optimized for a small number of read/write streams Optimized for large files (multi-megabyte and up) Not primary storage! Not a general purpose fileserver or SAN filesystem!

11. Confidential11 Example of Capacity Optimized Storage AA BBCDEFDF Full #1 CDG Incr #1 CHG Incr #2 BBCEDDIHGFF Full #2 A BCDEF A BCDEFA = New unique data = Repeat data = Pointer to unique data segment = Compressed unique data on disk G G H H I I

12. Confidential12 First full backup: 2-4x data reduction File-level incrementals: 6-8x Subsequent full backups: 20-60x Aggregate with Weekly Fulls, Daily Incrementals: ~20x Weeks in use Data Stored in TB Traditional Storage Capacity Optimized 1 TB data set 1 full + 6 incr / week Capacity Optimization: Over time Disk Savings 0 10 20 30 1 3 5 7 9 11 13 15 17 19

13. Confidential13 Capacity Optimization: Review Overall compression = Global * Local  Global compression: Replace non-unique segments with references (2:1 to 100:1 or more common)  Local compression: LZ compression of unique segments and other metadata (2:1 common) The more redundancy the better  Fulls compress more than incrementals, but  ~7:1 compression of incrementals/snapshots common COS eliminates redundant patterns Incrementals/snapshots contain only changed blocks COS eliminates redundancy BETWEEN changed blocks

14. Confidential14 Data Domain Value Statement  Replication (Wan Vaulting)

15. Confidential15 Wan Vaulting - General Information Functionality: WAN and LAN asynchronous replication Target Usage: Remote Office Backup/Recovery and Disaster Recovery Two Types – both included with Replicator license  Collection Replication - one system R/W and another R/O  Directory Replication - both systems can be R/W

16. Confidential16 Collection Replication – Full system replication Retention/ Restore ClientsServer Primary storage Backup/ media server WAN Onsite Retention Storage Offsite Disaster Recovery Storage Archive to tape As required Backup Replication DR

20. Confidential20 Verifies Recoverability at Backup Time Conventional file systems have no online consistency checks  Would discover problems only during restore DD OS tests full data path asynchronously quickly after backups  File system consistency  Data integrity on disk Continuous, proactive online verification and correction ongoing All verification is automatic and requires no manual intervention Data 1Strong checksum 2Complete write to disk 3Read back through filesystem 4Compare to checksum

21. Confidential21 Data Invulnerability Storage Foundation NVRAM support: powerfail-safe disk buffer  Protects against lost data in powerfail and software crashes  Fast consistency & integrity check after a system fault  Fast recovery after a system fault DD OS RAID 6 mirroring protects disks  Corrects block errors with redundant parity information System management simplicity  Recovery copies managed by backup software  Easy integration with tape systems for offsite storage  Manage the system with 21 commands  E-mail ‘phone-home’ diagnostics

22. Confidential22 Data Domain Cost Savings Capacity Optimized Storage  Global Compression Capacity Optimized Replication  95% Reduction in Bandwidth Requirements Integrates with Existing Backup Infrastructure  Ease of Integration  Minimize training
