Data-at-Rest: A Complete Solution
9/20/2011 Crossroads Europe GmbH
• Wikipedia says it iso A virtual tape library (VTL) is a data storage virtualisation
technology used for backup and recovery purposeso Virtualizing disk storage as tape allows integration of VTLs with
existing backup software and existing backup and recovery processes and policies
o Most current VTL solutions use SATA disk for primary storage due to relatively low cost
o eliminates streaming problems that often impair efficiency in tape drives as disk technology does not rely on streaming
o 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
o In some cases, the data stored on the VTL's disk array is exported to other media, such as physical tapes
Definition of a Virtual Tape Appliance
9/20/2011 Crossroads Europe GmbH
• Proven Technology:o Known in the Mainframe since 1997o Used in the Open Systems Environment since 2001o Physical tape becomes an option as needed
• Trend o Within Mainframe still much requesto Within Open Systems ongoing request
VTL Market
9/20/2011 Crossroads Europe GmbH
• VTLs work with all existing backup software, processes and procedures. In other words, everything works exactly as it would with a physical tape library. So IT-Management saves money, because little money has to been spend for additional training of administrators and changes of processes.
• With VTLs it is easy to share VTLs among multiple servers and applications. To share a VTL among multiple backup servers running the same software, use the built-in library sharing capability that most commercial backup products have. To share a VTL among multiple servers running different applications, partition the VTL into multiple smaller VTLs, assign a certain number of virtual cartridges to each VTL and associate each VTL with a different backup server.
