Abstract
Embodiments of systems and methods for implementing a file system utilizing a media library are disclosed. In particular, embodiments may present a network based file system to one or more host devices. These host devices may utilize the network based file system to organize, store, read or perform other operations in association with files. These files may be managed in conjunction with the media library.
Claims21
A system for providing a network based file system, comprising:
- a media library, comprising:
- a set of drives, and
- a set of tapes formatted according to the Linear Tape File System (LTFS);
- and
- an archive node appliance coupled to the media library and a set of hosts, the archive node appliance comprising a processor, a data store and a set of computer instructions executable on the processor to:
- present an interface to a network based file system to the set of hosts,
- receive a request to store a file at a first location associated with the network based file system over the network based file system interface, wherein the first location was created by a user at one of the set of hosts using the interface to the network based file system,
- store the file on the data store,
- store the file at a second location on a tape of the media library, wherein the second location mirrors the first location and storing the file at the second location comprises:
- determining the tape of the set of tapes on which the file is to be stored,
- determining if the tape is in one of the set of drives and if not, loading the tape into a drive,
- mounting the LTFS file system of the tape,
- determining if the second location exists on the tape and if not, creating the second location on the tape, and
- storing the file at the second location on the tape,
- maintain a map between the first location and the second location,
- receive a request to read the file at the first location associated with the network based file system,
- determine the tape on which the file is stored,
- access the file on the tape at the second location, and
- respond to the request to read the file over the network based file system interface using the file on the tape, wherein responding to the request to read the file comprises:
- determining the tape on which the file is stored using the map and the first location,
- determining if the tape is in one of the set of drives of the tape library and if not, loading the tape into the drive,
- mounting the LTFS file system on the tape, and
- accessing the file on the tape at the second location using LTFS.

A non-transitory computer readable medium comprising a set of instructions, the instructions for:
- presenting an interface to a network based file system to a set of hosts;
- receiving a request to store a file at a first location associated with the network based file system over the network based file system interface, wherein the first location was created by a user at one of the set of hosts using the interface to the network based file system;
- storing the file on a data store;
- storing the file at a second location on a tape of a media library comprising a set of drives and a set of tapes formatted according to the Linear Tape File System (LTFS), wherein the second location mirrors the first location and storing the file at the second location comprises:
- determining the tape of the set of tapes on which the file is to be stored,
- determining if the tape is in one of the set of drives and if not, loading the tape into a drive,
- mounting the LTFS file system of the tape,
- determining if the second location exists on the tape and if not, creating the second location on the tape, and
- storing the file at the second location on the tape;
- maintaining a map between the first location and the second location;
- receiving a request to read the file at the first location associated with the network based file system;
- determining the tape on which the file is stored;
- accessing the file on the tape at the second location;
- and
- responding to the request to read the file over the network based file system interface using the file on the tape, wherein responding to the request to read the file comprises:
- determining the tape on which the file is stored using the map and the first location,
- determining if the tape is in one of the set of drives of the tape library and if not, loading the tape into the drive,
- mounting the LTFS file system on the tape, and
- accessing the file on the tape at the second location using LTFS.

A method for implementing a network based file system, comprising:
- presenting an interface to a network based file system to a set of hosts;
- receiving a request to store a file at a first location associated with the network based file system over the network based file system interface, wherein the first location was created by a user at one of the set of hosts using the interface to the network based file system;
- storing the file on a data store;
- storing the file at a second location on a tape of a media library comprising a set of drives and a set of tapes formatted according to the Linear Tape File System (LTFS), wherein the second location mirrors the first location and storing the file at the second location comprises:
- determining the tape of the set of tapes on which the file is to be stored,
- determining if the tape is in one of the set of drives and if not, loading the tape into a drive,
- mounting the LTFS file system of the tape,

- receiving a request to read the file at the first location associated with the network based file system;
- determining the tape on which the file is stored;
- accessing the file on the tape at the second location;
- and
- responding to the request to read the file over the network based file system interface using the file on the tape, wherein responding to the request to read the file comprises:
- determining the tape on which the file is stored using the map and the first location,
- determining if the tape is in one of the set of drives of the tape library and if not, loading the tape into the drive,
- mounting the LTFS file system on the tape, and
- accessing the file on the tape at the second location using LTFS.
