Backup and Recovery A Look Back

• Backup-focused
• Tape-based
• Media management issues
• Slow recoverability
• Error-prone
• Reliability concerns
• CAPEX/OPEX issues
• Process of managing tapes expensive and
  time-consuming
• Hardware and media costs high
• Backup performance consistently major issue

Data Protection Today

• End-user trends
• Continued strong adoption of disk-based data
  protection technologies
• Recent ESG Snapshot Survey (October 2006)
• 50 of respondents doing D2D2T
• 19 backing up to disk only
• Only 21 still using tape exclusively
• Previous ESG Research (March 2005)
• 69 doing D2D2T
• 18 backing up to disk only
• 82 using tape exclusively
