Difference between Backup & Archive • Backups are created to recover from errors > Cost effective data protection > Off-site storage > Backup is important – Restore is Critical • Archiving for Information Lifecycle Management > Storing data on different media based on policy > “Right Data, Right Place, Right Price” 4

Why tape? Average price per GB $500 0 $6 0 Solid State Disk ($2000$5000) SCSI, FC Enterprise Disk ($40 -$70) FICON, ESCON, SCSI, FC $4 5 $3 0 $1 5 $ 0 Optical Disk Blue Laser ($15 -$35) SCSI Midrange Disk ($15 -$35) SCSI, FC Economy Disk ($3$15) JBOD, MAID, SATA Automated Tape ($. 50$3. 00) Storage Device Category • All prices are ASP per gigabyte for working subsystems. • The price per gigabyte decreases as the ratio of cartridges to drives increases, diverging from disk costs. • Automated tape prices include drives, media and library and use a 2 -to-1 compression factor. • Tape cartridge capacity growing faster than disk drive capacity. • Tape pricing per gigabyte now diverging from disk pricing.

Traditional Tape Based Backup • Primary storage to archival storage • Direct relationship with tape devices • Additional device sharing software Tape automation Backup servers Application servers Data moves directly from primary storage to tape and is managed by the backup application 10

Disk to Disk Backup • Add secondary disk storage > Part of existing disk subsystem or as an external appliance Backup servers Application servers Tape automation Data protection appliance - Snapshot/mirrors - Continuous data protection (CDP) Disk based snapshot/mirroring Data moves from primary storage to temporary disk buffer. Backups usually take place from the temporary location to tape. 11

Disk to Tape Backup • Add disk to existing backup servers • No additional hardware or software Backup servers Tape automation Application servers Data moves from primary storage to the temporary disk buffer and then on to tape. Data movement is managed by the backup application. Recoveries will normally come from the disk buffer(s). 12

Disk to Disk with Virtual Tape • Add virtual tape services with a storage appliance Backup servers Tape automation Application servers VTL virtual tape library Data moves from primary storage to the VTL disk buffer under control of the backup application. Recoveries normally take place from the VTL buffer. If a real tape cartridge is required then the backup application is responsible for creating it. 13

Continuous Data Protection • A disk-based data protection system that continuously echoes changes as they happen A B CDP Engine IP Subnet C A AA A B BB B CC C 14

Choose the Right Tape Technology • Capacity > Important for backup > Very important for most archive requirements > Not so important for HSM functionality • Throughput > Important for backup and archive > Backup must write several stripes because of the speed • Loadtime > Important for HSM functionality • Reliabilty 26

Archive Software 43

‘Infinite Disk’ Technology SAM-FS creates a virtualized or “infinite disk” that extends primary or secondary storage onto any number of additional media and devices. Virtualization optimizes storage capacity – automatically migrating inactive data to near-line secondary media – while also giving users immediate access to ALL of their data, regardless of where it is stored. Free Space Active Data (Frequently-Used Files) Pointers to Inactive Data on Secondary Media 44

SAM-FS Function: Archive Populate all tiers of storage based on data policy File Servers Users On-line Secondary Storage Data copied to media by policy Documents Spreadsheets Presentations Images Printstreams Automatically populate all desired tiers of storage Databases Video/Audio Messaging LAN/SAN Clients Generate up to 4 copies concurrently Data written in TAR format Optimized writes based on file size Shell command for immediate response Off-Site Storage 45

SAM-FS Function: RELEASE Automate primary disk space management File Servers Users On-line Secondary Storage Data copied to media by policy Documents Spreadsheets Presentations Images Printstreams Automatically populate all desired tiers of storage Databases Video/Audio Messaging LAN/SAN Clients Release only after valid copy exists Release directly after archiving Release at Watermarks Never Release – data stays on disk Shell command for immediate response Off-Site Storage 46

SAM-FS Functions: STAGE Managing retrievals from secondary storage File Servers Users On-line Secondary Storage Documents Data copied to media by policy Spreadsheets Presentations Documents Spreadsheets Presentations Images Printstreams Databases Automatically populate all desired tiers of storage Video/Audio Messaging Databases Video/Audio Messaging LAN/SAN Clients Associative Staging - Files can be staged in groups Read-behind Stage - Data immediately available while file is being retrieved Never Stage - Direct read on retrieval request from secondary storage Off-Site Storage 47
