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 streamsOptimized for large files (multi-megabyte and up)Not primary storage!Not a general purpose fileserver or SAN filesystem!

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

Data Domain Value Statement
Replication (Wan Vaulting)
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

Data Domain Value Statement
Reliability (Data Invulnerability)
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 1 Strong checksum
2 Complete write to disk
3 Read back through filesystem
4 Compare to checksum
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
