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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 2
Zmanda • Leader in Open Source Backup & Cloud Backup – ~1, 000 protected systems – 1000+ Cloud Backup customers • Open Source. Open APIs. Open Formats. – Smashes traditional backup business model • Cloud Backup Specialist Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 3
Cloud Backup • Backup to Cloud – Backup on-premises data to Storage Cloud (e. g. S 3) • Backup of Cloud – Backup applications running on Compute Cloud (e. g. EC 2) Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 4
Storage Cloud 101 • Unlimited storage available over the Internet • On-demand 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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 5

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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 7

Tape: Long Survivor Tapes survived because of several benefits, including ease of vaulting to a remote site Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 10
What about $3 B+ 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, Media and Robotics will move to Cloud Storage Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 11
Barriers to Cloud Storage Adoption • Privacy/Trust/Political • Bandwidth • 1 TB backup over a weekend needs ~25 Mbps uplink (assuming 50% compression of data) Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 12

Storage Provisioning • Huge problem for IT Managers • Over-provisioning: Expensive • Under-provisioning: Hara-kiri • Cloud Storage: Problem Solved! Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 14
Advantage of Open Locking up your backup data in proprietary formats (including proprietary clouds) comes with a *huge* cost and pain Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 17
Cost Comparison Backup-to-Tape vs. Backup-to-Cloud Backup-to-Tape Backup-to-Cloud • Backup Server • Backup Software • WAN Bandwidth • Tape Library • Cloud Storage • Tape Drives • Tapes • Hardware support • Space and Electricity • Transportation • Remote Secure Vaulting Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 19
Cost Comparison Example – Tape Backup Cost Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 20
Shipment/Transfer Costs • Tape pick up and storage services typically start at $200/month • What is the additional cost for your bandwidth? Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 21
Compliance • Location matters! • Country-specific regulations • Vertical Specific Compliance Requirements • E. g. Medical Records • Reporting • Retention Policy Management Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 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 Zmanda Cloud Backup www. zmanda. com Twitter: @zmanda 23
