Virtual Tape Library is a back up method, which combines tape back up emulation software with the hard disk and improves back up and recovery solution. VTL is quicker, flexible, consistent and cost effective. The virtual tape appliance emulates traditional tape devices. VTL functions with a disk-to-disk back up and commonly known as VTL D2D.

The virtual tape library provides all facilities of conventional tape methodology. It is fast and accessing files is almost instant. Moreover, using disk arrays one can store data more than one terabyte. Remote stations or work stations which are allied or configured will be able to access the virtual tape library without employing more 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 maximum security. In case of theft, fire, or any untoward incident the VTL will be there to rebuild the system.

The recovery time in a physical library is time consuming and VTL is much faster. The technology of tape use has become outdated as they have an expiry date for a limited period. Thus for back up system organizations are using VTL. The only disadvantage of VTL is it occupies considerable 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 allow data compression and side by side keeps track of the blocks it has stored to identify in future. For SME some companies have developed VTL storage system for disk storage, optical storage, etc. This is an expanding stage of VTL.

Recently customers have started realizing the value of VTL and have started deploying it. VTL resolves the complex storage network system. To be specific virtualization provides a storage system as if it is in a single drive. The virtual system and the host share the same software. Multiple systems can function with one physical computer.

An organization can have a computer with high processing power and sufficient memory and by adopting virtualization can run multiple operating systems. This is a very productive and cost saving method to adopt.

The iSCSI SAN Virtual storage server is a cost saving investment for company expansion. Conventional storage system has limited capacity and when you think to upgrade all what is essential is to install iSAN module to the existing server. It increases storage capacity of the system.

For a perfect back up of data from the hard disk adopt

iSCSI virtual tape

and to enhance the existing storage, the best available is
