Many of you know VTL( Virtual Tape Library) is very popular these days, there are many companies are migrating from traditional tape solutions to VTL. But VTL is not something new that has come in the technology space, the VTL Storage Technology is available from mainframe days.

People who are new to VTL Technology you can read the below post about what is VTL ?

What is VTL ?

A virtual tape library (VTL) is a disk-based backup system which appears to the backup host as a real tape library system. But Backup streams are written to and restored from disk.Virtual Tape Library is a piece of software which will emulate wired verity of Tape Libraries and tape drives.

Wiki :A virtual tape library (VTL) is a data storagevirtualization technology used typically for backup and recovery purposes. A VTL presents a storage component (usually hard disk storage) as tape libraries or tape drives for use with existing backup software.

There are plenty of virtual tape library vendors available in the market with lots of solutions. I was looking for Virtual Tape library software which supports IBM Spectrum protect software for my lab testing purpose,I have tried few solutions but their limitation in terms of compatibility features locking trail editions etc., recently I have tried a product called ” QuadStor” . found it very useful. I thought I wanted to share with you all, if someone is looking VTL solution I recommend to try this out. this product is completely free.

Step by Step installation of Virtual Tape Library-QUADSTOR

A virtual tape library (VTL) is a data storagevirtualization technology used typically for backup and recovery purposes. A VTL presents a storage component (usually hard disk storage) as tape libraries or tape drives for use with existing backup software.

Virtualizing the disk storage as tape allows integration of VTLs with existing backup software and existing backup and recovery processes and policies. The benefits of such virtualization include storage consolidation and faster data restore processes. For most mainframe data centers, the storage capacity varies, however protecting its business and mission critical data is always vital.

Most current VTL solutions use SAS or SATAdisk arrays as the primary storage component due to their relatively low cost. The use of array enclosures increases the scalability of the solution by allowing the addition of more disk drives and enclosures to increase the storage capacity.

The shift to VTL also eliminates streaming problems that often impair efficiency in tape drives as disk technology does not rely on streaming and can write effectively regardless of data transfer speeds.

By backing up data to disks instead of tapes, VTL often increases performance of both backup and recovery operations. Restore processes are found to be faster than backup regardless of implementations. In some cases, the data stored on the VTL's disk array is exported to other media, such as physical tapes, for disaster recovery purposes (scheme called disk-to-disk-to-tape, or D2D2T).

Alternatively, most contemporary backup software products introduced also direct usage of the file system storage (especially network-attached storage, accessed through NFS and CIFS protocols over IP networks) not requiring a tape library emulation at all. They also often offer a disk staging feature: moving the data from disk to a physical tape for a long-term storage.

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.

History[edit]

The first VTL solution was introduced by Cybernetics in 1992 under the name HSTC (high speed tape cache).[1] Later, IBM released a Virtual Tape Server (VTS) introduced in 1997. It was targeted for a mainframe market, where many legacy applications tend to use a lot of very short tape volumes. It used the ESCON interface, and acted as a disk cache for the IBM 3494 tape library. A competitive offering from StorageTek (acquired in 2005 by Sun Microsystems, then subsequently by Oracle Corporation) was known as Virtual Storage Manager (VSM) which leveraged the market dominant STK Powderhorn library as a back store. Each product line has been enhanced to support larger disk buffer capacities, FICON, and more recently (c. 2010) 'tapeless' disk-only environments.

Virtual

Other offerings in the mainframe space are also 'tapeless'. DLm has been developed by EMC Corporation, while Luminex has gained popularity and wide acceptance by teaming with Data Domain to provide the benefits of data deduplication behind its Channel Gateway platform. With the consequent reduction in off-site replication bandwidth afforded by deduplication, it is possible and practical for this form of virtual tape to reduce recovery point objective time and recovery time objective to near zero (or instantaneous).

Outside of the mainframe environment, tape drives and libraries mostly featured SCSI. Likewise, VTLs were developed supporting popular SCSI transport protocols such as SPI (legacy systems), Fibre Channel, and iSCSI.

The FalconStor VTL is the foundation of nearly half of the products sold in the VTL market, according to an Enterprise Strategy Group analyst.[2]

In mid-2010s VTLs got a rebirth thanks to hi-capacity 'archive' drives from Seagate and HGST and more popular 'tape in cloud' and Disk-to-Disk-to-Tape (often in cloud) scenarios. [3]
