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”

• 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
Application servers
Tape automation
Backup servers
Data moves directly from primary storage to tape and is managed by the backup application
11
Disk to Disk Backup
• Add secondary disk storage> Part of existing disk subsystem or as an external
appliance
Application servers
Tape automationBackup
servers
Data moves from primary storage to temporary disk buffer. Backups usually take place from the temporary location to tape.

Disk to Disk to Tape Backup
Application servers
Tape automation
Backup 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).
• Add disk to existing backup servers• No additional hardware or software
13
Disk to Disk with Virtual Tape
Application servers
Tape automationBackup
servers
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.
VTLvirtual tape library
• Add virtual tape services with a storage appliance
14
• A disk-based data protection system that continuously echoes changes as they happen

Let’s see the difference for archive!
• Components of recall time> Mount tape (by robot)> Load tape> Find block> Transfer data> Rewind> Unload> Dismount tape (by robot)
It doesn’t help if this component is fast when
therest are slow.
26
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

The Judges Reach Their Decision -Sun StorageTek L1400M Product of the Year • As one of our judges put
it, it may be "somewhat contrarian" to give the gold to a tape library in 2006, but Sun Microsystems Inc.'s L1400M solves a top problem in tape:> The ability to use four
different tape formats within a single library
• “It's a solution that's been a long time coming.”

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.
