  1. Virtual Tape Library

  2. NetApp - Major acquisitions • 2005 - Alacritus: The tape virtualization technology Alacritus brought to NetApp was integrated into the NetApp NearStore Virtual Tape Library (VTL) product line, introduced in 2006.

  3. NetApp - Filers • In 2006, NetApp launched a Virtual Tape Library (VTL) product for magnetic tape data storage virtualization.

  4. iSCSI - Targets • The underlying implementation can deviate drastically from the presented target as is done with virtual tape library (VTL) products

  5. High-performance computing - Software tools and message passing • The parallel architectures of supercomputers often dictate the use of special programming techniques to exploit their speed. Software tools for distributed processing include standard Application programming interface|APIs such as Message Passing Interface|MPI and Parallel Virtual Machine|PVM, Virtual tape library|VTL, and open source-based software solutions such as Beowulf (computing)|Beowulf.

  6. Data deduplication - Source versus target deduplication • * Target deduplication is the process of removing duplicates of data in the secondary store. Generally this will be a backup store such as a data repository or a virtual tape library.

  7. Data deduplication - Major players and technologies • * CA's ARCServe and XOsoft, SIR, FDS (Virtual Tape Library, Single Instance Repository, and File Deduplication System)

  8. FalconStor - Products • FalconStor's Software includes Virtual Tape Library (Virtual tape library|VTL) with data deduplication, Continuous Data Protector (Continuous Data Protection|CDP), File-interface Data deduplication|Deduplication System (FDS) and Network Storage Server (NSS), each enabled with Wide area network|WAN-optimized replication for disaster recovery and remote office protection

  9. Cofio Software - ViStor • ViStor is a software implementation of a Virtual Tape Library (VTL). It was released in 2007 to OEM's in Asia specifically who create VTL appliances using the ViStor software. Software runs on a version of Linux and supports the iSCSI protocol as well supporting Emulex Fibre Channel Host Bus Adapters. This product was EOL after the HDS acquisition.

  10. Data Domain (corporation) - History • Unlike most of its early competition, it was first packaged as a file-system appliance; this made it more predictable than a software product and simpler to manage than a virtual tape library system.

  11. Virtual Tape Library • A 'virtual tape library' ('VTL') is a computer storage|data storage Storage virtualization|virtualization technology used typically for backup and recovery purposes. A VTL presents a storage component (usually hard disk storage) as tape library|tape libraries or tape drives for use with existing backup software.

  12. Virtual Tape Library • While a virtual tape library is very fast, the disk storage within is not designed to be removable, and does not usually involve physically removable external disk drives to be used for data archiving in place of tape. Since the disk storage is always connected to power and data sources and is never physically electrically isolated, it is vulnerable to potential damage and corruption due to nearby building or power grid lightning strikes.

  13. IBM Tivoli Storage Manager - Product details • Actual user data is managed via a cascading hierarchy of storage media (Primary Storage Pools) presented as raw devices (UNIX), filesystem containers (Windows and Linux), streaming tape or optical media. Additionally, emulated tape from a Virtual tape library|Virtual Tape Library or EMC Corporation|EMC Centera WORM archival device are supported. Duplicate copies (Backupsets or Copy Storage Pools) of any subset of data may be created on sequential media for redundancy or off-site management.

  14. IBM Storage - Virtual tape libraries • * TS7620 ProtecTIER Deduplication Appliance - Preconfigured repository that can be configured with either a Virtual Tape Library or Symantec OpenStorage interface with a capacity of up to 35 TB.

  15. IBM Storage - Virtual tape libraries • * IBM Virtualization Engine TS7700 series - The TS7700 is a virtual tape library for System z (mainframe) that uses disk drives for cache to accelerate backup operations

  16. Seven tiers of disaster recovery - Tier 3: Electronic vaulting • The facilities for providing Electronic Remote Vaulting consists of high-speed communication circuits, some form of channel extension equipment and either physical or a virtual tape library and an automated tape library at the remote site

  17. Glossary of backup terms - Terms and definitions • ; virtual Tape Library (VTL) : a storage device that appears to be a tape library to backup software, but actually stores data by some other means. A VTL can be configured as a temporary storage location before data is actually sent to real tapes or it can be the final storage location itself.

  18. Disk staging • The process of disk staging is controlled by the same software that performs actual backups, which is different from virtual tape library where intermediate disk usage is hidden from main backup software. Both techniques are known as D2D2T (disk-to-disk-to-tape).

  19. Network Appliance, Inc. - Major acquisitions • * 2005 - 'Alacritus': The magnetic tape data storage|tape virtualization technology Alacritus brought to NetApp was integrated into the NetApp NearStore Virtual Tape Library (VTL) product line, introduced in 2006.
