Symantec OpenStorage API Support

FalconStor VTL is the industry’s rst VTL to integrate with Symantec OpenStorage using APIs. This will give NetBackup 6.5 users direct access

to FalconStor VTL functions (capacity, de-duplication, replication, and others) through the NetBackup management console.

Certification pending

Allows for intelligent use of backup capacity

NetBackup can age backup images independent of media

NetBackup will free up backup images when no longer needed

NetBackup is aware of de-duplication capacity

NetBackup can perform partial restore without the need to “read-past” unneeded data in large backup sets

NetBackup aware of replication of backup images to remote sites

Enhancements to existing features

Next generation data de-duplication

FalconStor VTL features a fully-integrated option for next-generation data de-duplication, called Single Instance Repository (SIR). De-

duplication via SIR dramatically reduces the storage footprint required for a given amount of data as well as the bandwidth required to

move it from one site to another. SIR reads the virtual tape cartridges, determines their format, calculates a unique data identier for each

piece of data, and stores a single copy of each unique piece. The original virtual tape cartridge is replaced by a virtual index tape containing

the backup metadata and pointers to the unique pieces of data that comprised the original. The virtual index tape is typically only 1/100 the

size of the original virtual tape cartridge. De-duplication is performed post-process, after the backup completes, to optimize storage

eciency without aecting the backup window.

Global, clustered de-duplication architecture

FalconStor de-duplication oers clustering with an N+1 failover architecture. Multiple de-duplication appliances can be virtualized as one,

providing linearly scalable throughput and processing power. If one fails, the standby system will automatically take over its workload to

ensure continuity. All notes within the cluster maintain single de-duplication repositories, such that a unique block is never stored in more

than one node. The cluster maintains a single hash table, so it does not compromise the de-duplication ratio.

For large organizations with multiple remote sites, global de-duplication enables ecient centralized data consolidation. FalconStor VTL

enables remote replication for DR through an existing WAN. By replacing traditional manual transportation with network transfer and data

encryption, FalconStor VTL lowers tape management costs and the risks of data loss. In the process of remote replication, only unique data

blocks are replicated to the remote site, reducing network trac by as much as 95% based on a 20:1 de-duplication ratio.

FalconStor VTL supports both one-to-one and many-to-one replication congurations to enable tape infrastructure consolidation at the data

center. With VTL Storage Appliances deployed at each site, virtual tapes can be replicated via WAN to the data center, where VTL aggregates

the data into a clustered repository of globally unique data. At each site, VTL Storage Appliances perform de-duplication by checking if the

same data blocks exist at the data center, replicating only unique data. Since identical data often exists at multiple sites, VTL Storage Appliances

oer global de-duplication to further reduce network trac and DR costs. Once data is at the data center, the appliance can migrate it to

physical tape for archival or compliance purposes.

Tape caching

This lets you set up policies that will automatically trigger the export to physical tape. Files can be restored from either the virtual or physical

tape copy. The operation is totally transparent to the backup software so there is no impact to existing policies. Enhancements include

direct-link allocation to physical tapes, customizable manual migration, and a reclamation option to prevent accidental deletion from

physical tape.

Hardware compression

FalconStor VTL now supports Hifn Express DR 600 and Hifn Express DR 1000 hardware compression boards. Hifn uses PCI Express and oers

up to 600 MB/sec of compression and decompression for the DR 1000 card.
