Abstract

A method and system for integrating a physical tape library format into a Virtual Tape Library (VTL) library product is disclosed. The physical library format may include, but not limited to, a Linear Tape File System (LTFS) format. The method and system involves facilitating manage of data storage between the physical tape libraries and the VTLs.

Method and System for Integrating LTFS into VTL Library Products

Disclosed is a method and system for integrating a physical tape library format into a Virtual Tape Library (VTL) library product. The physical library format may include, but not limited to, a Linear Tape File System (LTFS) format. The method and system involves facilitating manage of data storage between the physical tape libraries and the VTLs. Fig. 1 represents the VTL apparatus.

Further, the Fig. 2 represents steps involved in integrating the LTFS format into the VTL library products. In a first step, a VTL server may present a tape and a LTFS front end to an application host through a fiber channel interface residing in the VTL server and application software. In a second step, the application host may send a data for storage to the VTL server. The data for storage may be in a form such as, but not limited to, a LTFS format and a tape format. For an instance, an application host may be a backup application or a user storing files directly from the application host. In a third step, the VTL server may format metadata array pointers to point to the data stored in the VTL sever. In one instance, such as a normal tape formatted data, the metadata array pointers may use a linear format such as, but not limited to, LTO 5 formatted data. In another instance, such as a LTFS formatted data, the metadata array pointers may use the LTFS format such as, but not limited to, LTO 5 LTFS formatted d...
