 +===== About VTL =====
 +
 +This segment is stolen from the [[http://en.wikipedia.org/wiki/Virtual_tape_library|Wikipedia article on VTL]]:
 +
 +> A virtual tape library (VTL) is a data storage virtualization 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 linux, we have an experimental implementation of file-based VTL in the form of [[http://sites.google.com/site/linuxvtl2/|linuxvtl2]], thanks to the work of Mark Harvey. It is based on the work done with the [[http://sg.danny.cz/sg/sdebug26.html|scsi_debug]] adapter driver, and consists of a combination of a kernel character device driver and userspace tools.
 +
 +I will in general reference this implementation by its "official" name, linuxvtl2, and more often by its in-use name, mhvtl (obviously named after Mark Harvey).
