3 Backup Redesign is Hot What are your top initiatives? % Respondents The InfoPro Wave 13 (12/8/09)

4 Why? Dedupe changes everything

5 Shift to Dedupe 76%-100% 51%-75% 26%-50% What percentage of your VTL is using deduplication today? By 2011? 21%-25% 16%-20% 11%-15% %-10% % 20% 40% 60% 80% % Respondents The InfoPro Wave 13 (12/8/09)

6 Recovery Architectures In Transition from Tape to Disk Recovery Architecture Application Backup Clients Media Manager Onsite Backup Storage Disaster Recovery Storage Conventional (Tape-centric) Backup software VTL Tape Backup software VTL Tape/VTL Backup software Deduplication Transformational (Disk-centric) VM Deduplication backup software and system on premise off premise

7 Classic Tape Tape library Offsite Tape stores redundant copy Tape manually moved off site for DR Older tapes for time travel Tape was cheap; got the job done

8 Add Staging Disk Still Tape Centric Staging disk Tape library Offsite Disk improves backup success rate Speed matching buffer Critical restores may come from disk Tape for DR and time travel

9 Add Staging Disk Still Tape Centric Staging disk Tape library Key features: Minimal change to processes Performance Automatic copy to tape It s really about the tape Offsite

10 Add Deduplication Disk Tape-Centric, but Less Tape Dedupe Tape library Offsite Keep all operational copies local All operational restores from disk Avoid recalling tapes from offsite DR still manual with tape

11 Add Deduplication Disk Tape-Centric, but Less Tape Dedupe Tape library Offsite Key features: Dedupe effectiveness to reduce cost Inline dedupe to reduce cost Data protection (extra copies are gone)

12 Add Dedupe Replication Disk-Centric, but Classic Architecture WAN Dedupe Dedupe replica Tape library DR copies offsite sooner and automatically Tape optional for archive Some companies choose no tape

13 Add Dedupe Replication Disk-Centric, but Classic Architecture WAN Key features: Dedupe Time till data is offsite Can t replicate till data is deduped Replication robustness WAN efficiency Dedupe replica Tape library

14 Integrate Replication with Backup Software Disk-Centric, but still Classic Architecture control Dedupe WAN Dedupe Replicate deduped data, but Backup software drives replication Catalogs replica backups separately Manages retention individually Single pane of glass Tape library

15 Virtual Full Backups Disk-Centric Redesign Deltas only WAN Dedupe Dedupe Leverage random access capabilities Send deltas only Efficiency of a replication protocol Stop doing regular full backup Huge win in virtual environments

16 VM Image-based Backup Disk-Centric Redesign Virtual Machines Deltas only WAN Host Dedupe Dedupe Copy changed blocks only Retain virtual disk snapshots Use full image for DR, migration, etc. Crack open image for granular restore

17 Journey to Disk-Centric Data Protection Disk first just augmented the classic tapecentric architecture Deduplication presents an opportunity to rethink backup Use disk as disk Deduplication appliances Help a classic architecture Are perfect transition to disk-centric Consider current and future requirements Look at disk-centric backup packages for the greatest leverage
