This document discusses transforming offsite backups into a true data recovery option. It outlines that backups should provide file history, have a catalog, be durable and secure with encryption. Backups are different than storage, replication or archive solutions. The ideal backup solution should be inexpensive, granular, restore files reliably and minimize business disruption from data loss or corruption. Avamar is highlighted as a backup solution that provides variable length deduplication and SHA-1 hash verification for reliability and low storage overhead.

- 5. Amazon S3 / Glacier as Backup? • 99.9% Uptime • 10.1 Minutes aWeek of Downtime • Questionable Data Durability • HowValuable isYour Data? • 3 to 5 Hours ResponseTime • No Recovery SLA • Charge to Reclaim Data • HowValuable isYour Data? Glacier
- 6. HowValuable is an SLA? • $100,000,000 = $274,000 a day • $11,416 an hour (24 x 7) • $100,000,000 = $384,515 a day • $32,042 an hour (12 x 5) • Amazon Has a Data Durability RatingThat’s 6x More ReliableThan a Consumer Hard Drive • HowValuable isYour Data?

- 8. Availability - Is Not Backup • Designed for 99.9999% Uptime • Very Expensive to Implement • Limited Physical Distance (50 miles) • Synchronous Replication • Zero to Seconds of DownTime aYear • Very Short to No Data History
- 9. Replication - Is Not Backup • Designed for 99.999% Uptime • Moderately Expensive to Implement • Longer Distance (hundreds of miles) • Asynchronous Replication • Seconds to Minutes of DownTime • Moderate Data Retentions • Minimizes RTOs / RPOs
- 10. Archive - Not Backup Glacier • The Business May Never Need It • If Someone Needs It, It’s Lawyers • You Can Wait Days for Access • You Will Pay to Access it Because You Most Likely Wont
- 11. Backup - What Is It? • It’sThe Sweet Spot • Inexpensive Relatively Speaking • Backup Should be Granular • Backup Should Provide a File History • Backup Should Have a Catalog • Backup Should be Durable & Secure • Backup Should Not Be Managed By Users • Backup Should… Restore
- 12. Backup - It’s not EFSS • EFSS Is Great… For Mobility • No Revision History • Data Corruption is Everywhere • Responsibility Managed By Users • No Data Protection
- 13. Backup - Not Snapshots • Snapshots Are Not Granular • Snapshots Are Not File History • Snapshots Have No Catalog • Snapshots Can Be Disruptive • No Encryption or Data Protection
- 14. Backup - Encrypted • Backup Should be Durable • Backup Should be Secure • Backup Should be Encrypted • InTransit • At Rest • Backups Should be Offsite

Editor's Notes
- Apple for example calls out 4.2 billion dollars on their balance sheet that’s “intangible assets” including intellectual property. Clearly the world if running on data, so how do we keep up with the growing demand, promises of quick recovery and the need to safeguard it in an offsite location?
