The Recovery Gap
The Gartner Group:“30% of all backups are not recoverable.”
The Yankee Group:“40% were unable to recover data.”
Symantec:“…one in four tests fail.”
What’s the Problem?What’s the Problem?

We see two reactions to these painful statistics.
• Sheep: • “Our backup success is 98%, don’t worry about it.”• “That doesn’t apply to us because ….”
• Wolves: • “Really? How can that happen?”
• Our whitepaper has 10 very common scenarios where backups succeed – but then recoveries fail.
• “How can we test our backups better?”

This technique always uncovers problems.And it’s quite feasible.

• ART restores a few files, chosen at random, from every computer TSM backs up.
• Restored files come to the ART VM. Production nodes are untouched.
• ART doesn’t restore huge files, hammer TSM, or disrupt migration, reclamation, etc.
• And … ART usually uncovers huge amounts of wasted storage.

• Easy install
• Supports storage audits (SOX, HIPAA)
• Prevents restore problems
• Finds rogue servers• Servers that are in production, but nobody told the
backup team about them. They’re not covered by TSM.
• Trims waste storage (sometimes 20 – 50%)
• Pricing: $35/node (less for larger sites).
