Aligning Backup, Recovery and Allen Ruster EMC Corporation May 9, 2006 Backup and Efficiencies Through ILM Enterprises seeking a successful approach to ILM must embrace a strategy that appropriately addresses the specific distinct requirements of backup and archiving. The Sageza Group...users will use disk-based backup as a point from which to embark upon a more dramatic redesign of their overall backup infrastructure Goldman Sachs, IT Spending Survey Common Backup and Pain Points Performance of backups Reliable recovery Tape infrastructure availability Management overhead Cost of tape media/libraries Risk associated with offsite media storage Long-term data retention 1
I don t know we d have to count the pallets.

Backup Backup and are Different For recovery Copies information Improves availability Short term in nature Typically overwritten Not for regulatory compliance For retrieval Moves information Adds operational efficiencies Long-term in nature Data typically maintained Useful for compliance Traditional Backup and Process Production Apps Production environment grows Backup Process Backup environment capacity tied to production growth Data retention environment expands rapidly and is difficult to manage Retention Copies The Life of a Typical 1 MB File User creates 1 MB ppt file and e-mails it to 10 people They all save the file on the network drive Later they put the e-mail in a PST folder on the network drive For an average customer, that one file gets backed up: 1. Weekly for four weeks x 10 on the file server = 40 copies 2. Daily for four weeks on the e-mail server = 28 copies 3. Monthly for five years x 10 of PST = 600 copies 4. Monthly for five years x 10 of file = 600 copies That 1 MB file takes up over 1.2 GB of tape capacity 3
Traditional Approach Leaves IT Struggling The same data is backed up over and over again Multiple identical copies of information Cannot finish backups in available windows Recoveries are slow and unpredictable Traditional Response? Add more tape, add faster tape Speed backup at the expense of recovery (Incrementals, multiplexing, or less frequent backups) New Architecture for Backup/Recovery and ❶ Recovery process ❸ ❹ Production ❷ ❹ process ❶Understand your environment - What am I backing up? How can I consolidate? ❷Actively archive valuable information to tiered storage ❸Back up to disk active production information ❹Retrieve from archive or recover from backup Aligning Backup, Recovery, and : Achieving Maximum Benefit Understand the Environment Online, Active Archiving Backup to Disk 4
