  1. Economics of Cloud Storage vs. Traditional Removable Media ChanderKant CEO Zmanda, Inc.

  2. Economics of Cloud Storage • For Secondary or Tertiary Storage • Macro view • Industry shift • Micro view • IT Manager’s Choice • Our view • Building a business on Cloud Storage

  3. Zmanda • Leader in Open Source Backup & Cloud Backup • ~1,000,000 protected systems • 1000+ Cloud Backup customers • Open Source. Open APIs. Open Formats. • Smashes traditional backup business model • Cloud Backup Specialist

  4. Cloud Backup • Backup to Cloud • Backup on-premises data to Storage Cloud (e.g. S3) • Backup of Cloud • Backup applications running on Compute Cloud (e.g. EC2)

  5. Storage Cloud 101 • Unlimited storage available over the Internet • On-demand and Elastic • Web services interface (REST, SOAP) • Other protocols can be built on top of these • Cost is typically based on actual storage and bandwidth used • Off-site • Ideal for Secondary and Tertiary Storage

  6. Economics of Cloud Storage • For Secondary or Tertiary Storage • Macro view • Industry shift • Micro view • IT Manager’s Choice • Our view • Building a business on Cloud Storage

  7. Backup Industry – still tangled up in Tapes • Tapes still a significant component of backup industry • Availability of high-capacity/low-cost (e.g. SATA) drives accelerated the trend away from Tapes • Per GB cost advantage of tape became 4:1 instead of historical 10:1

  8. Tape: Long Survivor • Tapes survived because of several benefits, including ease of vaulting to a remote site

  9. The End is Nigh • Following combined: • Inexpensive Disks • Reliable High Bandwidth Internet Access • Inexpensive or Free (Open Source) Storage Management Software • Provisioning Software • Business opportunity sensed by large-scale web-based businesses • For a potent brew: • Cloud Storage

  10. What about $3B+ Tape Industry? • Tape won’t be dead, but will become niche • Will be used for long term archiving with very high Recovery Time Objective (RTO) • Data in WORSE mode (Write Once Read Seldom if Ever) • Significant proportion of current spend on Tape Drives, Mediaand Robotics will move to Cloud Storage

  11. Barriers to Cloud Storage Adoption • Privacy/Trust/Political • Bandwidth • 1TB backup over a weekend needs ~25Mbps uplink • (assuming 50% compression of data)

  12. Economics of Cloud Storage • For Secondary or Tertiary Storage • Macro view • Industry shift • Micro view • IT Manager’s Choice • Our view • Building a business on Cloud Storage

  13. Storage Provisioning • Huge problem for IT Managers • Over-provisioning: Expensive • Under-provisioning: Hara-kiri • Cloud Storage: Problem Solved!

  14. Advantage of Open Locking up your backup data in proprietary formats (including proprietary clouds) comes with a *huge* cost and pain

  15. More robust than what you can buy • Amazon RRS is 400 times more durable than a typical hard disk • Acquire the risk profile of a much larger organization

  16. Performance Considerations • Full backup and Recovery time • Bandwidth consumption • Consider consumer-class dedicated link for uploads • Limited data transfers in the backup window • Perform Incremental Backups most of the time • Recovery performance and strategy very different from getting tapes shipped back to premises • Consider Hybrid Backup

  17. Cost ComparisonBackup-to-Tape vs. Backup-to-Cloud Backup-to-Tape Backup-to-Cloud Backup Software WAN Bandwidth Cloud Storage • Backup Server • Backup Software • Tape Library • Tape Drives • Tapes • Hardware support • Space and Electricity • Transportation • Remote Secure Vaulting

  18. Cost Comparison Example – Cloud Backup Cost • 1 TB backed up to cloud every month • 2 Months retention • 50% compression • Encrypt data before shipping • $0.15/GB/Month • Cloud Backup Monthly Cost: $150 • Three year cost: $5400

  19. Cost Comparison Example – Tape Backup Cost

  20. Shipment/Transfer Costs • Tape pick up and storage services typically start at $200/month • What is the additional cost for your bandwidth?

  21. Compliance • Location matters! • Country-specific regulations • Vertical Specific Compliance Requirements • E.g. Medical Records • Reporting • Retention Policy Management

  22. Why backup to cloud? • No capital expenses. Backup storage use is elastic in nature • Reduce infrastructure management tasks • Faster recovery from offsite backups • Geographic accessibility • Geographic choice (Cloud Storage locations are expanding fast!)‏ • More efficiency and reliability for SMB customers • Multiple cloud vendors to improve reliability • Backup data available in the cloud for additional analysis such as • e-discovery

  23. Economics of Cloud Storage • For Secondary or Tertiary Storage • Macro view • Industry shift • Micro view • IT Manager’s Choice • Our view • Building a business on Cloud Storage

  24. Cloud solved two major problems for us • We did not want to operate a data center • We did not want to meter and bill thousands of customers around the world

  25. ISV Business Model: S3 + DevPay • One of the first users of S3 + DevPay • DevPay is great but has limitations • Other Cloud Storage vendors are catching up to enable ISVs

  26. Zmanda Cloud Backup • Live Backup of Microsoft Exchange, SQL Server, and SharePoint • Live Backup of Open Files • Full and Incremental Backups • Network Drive support • Direct Backup to Cloud • D2D2C • Hybrid backup to both local disk and cloud

  27. Backup to 3 Continents Zmanda Cloud Backup

  28. Cloud Backup – Advanced Features • Location Control • Built-in data integrity check during data transfer • Transfer Block Size Control • Default block size is 10MB • Block size can be between 1KB and 100MB • Multi-threaded Uploads • Encryption • Can be turned off for public data

  29. Backup & DR on the Cloud Standby Virtual Machines Amanda Enterprise Server Virtual AE Server File Server AE S3 Option Internet DB Server Backup Images Email Server Replication of Configuration & Catalog Primary Location on the Cloud
