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

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
