What’s new in Virtual Tape Library (VTL)
Enterprise Edition v5
FalconStor® Virtual Tape Library (VTL) provides high-performance enterprise-level disk-based data protection and
integrated global data de-duplication to optimize storage and bandwidth utilization. Robust media management
simplifies tape management and enhances tape security. Offering multi-node scalability, FalconStor VTL emulates vast
arrays of tape libraries, drives, and cartridges, ensuring complete backup transparency. By enabling companies to keep
backup data on disk, FalconStor VTL significantly improves the speed and dependability of recovery.
New features
Multi-node management and architecture
With FalconStor VTL, up to 8 nodes may be managed as a single group through group policies and group reports. The group can consist of a
combination of high availability (HA) pairs of nodes and standalone nodes. This helps an organization’s IT staff to be more productive and
manage the VTL environment more easily. The following features are included:
> Single sign-on: One user id/password can be used to log into all nodes that are part of a multi-node group.
> Consolidated user management: Users can be added/deleted at the group level.
> Consolidated reporting: A single report is generated for all nodes in a group. This greatly simplifies management of very large
> Common configuration settings: A single point of management at the group level greatly reduces initial setup tasks and simplifies
ongoing configuration adjustments, even in large-scale deployments. The following configuration settings can be done at the group level
and applied to all member nodes:
• SNMP settings
• Storage monitoring trigger threshold
• Tape caching migration and reclamation thresholds
• SW/HW compression settings
• X-rays
Tape consolidation
Allows users to write multiple virtual tapes to a single physical tape of greater capacity. Tape consolidation effectively reduces IT
management costs and tape capacity requirements, eliminating wasteful space consumption on new, higher-capacity tapes.
Tape shredding
For security and regulatory compliance, shredding enables users to “destroy” a virtual tape so that it cannot be accessed, even if using disk
forensics. Shredding performs a three-pass wipe of the selected virtual tapes using an algorithm specified by the U.S. Department of Defense
(Standard 5220.22-M).
Multi-tape export
Enables users to make multiple physical copies of virtual tapes (up to five) for offsite disaster recovery (DR) and/or to meet regulatory
requirements. Multi-tape export may be set as part of automated tape caching or auto archive policy; or it can occur during manual export of
a single tape. Multi-tape export increases IT productivity, eliminating the need for manual tape duplication or scripting.
Export to physical tape via NDMP v4
Allows certified backup applications and industry-standard NAS appliances to back up to, and restore from, the VTL using NDMP protocol
over an IP network for both command and data flow.
Symantec OpenStorage API Support
FalconStor VTL is the industry’s first 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). Deduplication 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 identifier 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
efficiency without affecting the backup window.
Global, clustered de-duplication architecture
FalconStor de-duplication offers 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 efficient 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 traffic 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 configurations 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
offer global de-duplication to further reduce network traffic 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 offers
up to 600 MB/sec of compression and decompression for the DR 1000 card.

Replication with tape caching
With VTL, an automated tape caching policy and replication policy may be set on the same virtual tape. You can migrate to physical tape and
then replicate it to a remote site, or you can replicate it to a remote site and then migrate it to physical tape at the original site, all as part of the
same policy.
Incremental export
The incremental export feature optimizes the migration to tape process by reducing the amount of data moved to physical tape whenever
possible. If a virtual tape is migrated to the same physical tape to which it was migrated previously, only the modified data will be exported.
Both manual export and tape caching operations will benefit from this feature.
Enhanced job queue
To accommodate the increased number of jobs in the queue, jobs are displayed in the same way that virtual tapes are displayed – in the right
pane of the screen. When a job is highlighted, the lower part of the screen displays the details of the job. You can cancel, hold, resume, restart
a failed job, or delete a job directly from the right pane for one or more jobs.
Command Line Interface (CLI) for import/export
The command line utility has been enhanced to support import/export operations. All import/export operations available in the console are
supported from the command line.
The following enhancements have been made to the reporting feature:
> A variety of reports, including LUN virtual tape, physical tape usage, and SIR reports, can be scheduled to run at regular intervals
> Reports can be exported in PDF, HTML, and Excel formats, in addition to CSV and text
> Reports can be emailed automatically after they are generated
> Properties can be set to specify your SMTP configuration and define how long reports should be retained
IBM 3494 integration
Users no longer need to create a category of tapes before configuring an IBM 3494 system with VTL. Instead, VTL software automatically
creates the category for the user, who then assigns tapes to the category.
