Virtual tape library is a recovery and back up system. VTL is quicker, flexible, steadfast and cost effective. The virtual tape appliance emulates traditional tape devices. VTL functions with a disk-to-disk back up and frequently known as VTL D2D.
The virtual tape library provides all facilities of conventional tape methodology. It is fast and reaching files is almost instant. Moreover, using disk arrays one can store data more than one terabyte. Remote stations or work stations which are linked or configured will be able to access the virtual tape library without employing extra workforce. It works as a back up for both hard disk and tape. The cartridges should be removed from the location to a safer place for utmost security. The VTL helps rebuilding the system in case of any mishap.

The recovery time in a physical library is time spending and VTL is much faster. The technology of tape use has become outdated as they have an expiry date for a limited period. Therefore, many organizations are adopting virtual tape library as their back up system. The only disadvantage of VTL is it occupies substantial disk space. If only the data can be compressed then the cost may reduce to some extent. The compression appliances are also existing today.
In future VTL will use an aggressive compression method. This will permit data compression and side by side keeps track of the blocks it has stored to classify in future. For SME some companies have developed VTL storage method for disk storage, optical storage, etc. VTL is expanding in this line.
Recently customers have started realizing the value of VTL and have started deploying it. They have concluded that virtualization solves the problem of the management in complex storage network. To be specific virtualization provides a storage system as if it is in a single drive. The same software is used by the host and the virtual system. Multiple systems can work with one physical computer.
Multiple operating system can function if there is high speed processor with ample memory. This is a very profitable and cost saving method to adopt.
The iSCSI SAN Virtual storage server is a cost saving investment for company expansion. Conventional storage system has small capacity and when you think to upgrade all what is necessary is to install iSAN module to the existing server. It increases storage capacity of the system.
