Abstract

A computerized method for sharing removable storage media in a network, the method comprising associating, in an index entry, a first piece of removable storage media in a first storage device with at least a first storage policy copy and a second storage policy copy; copying, to the first piece of removable storage media, data associated with the first storage policy copy; and copying, to the first piece of removable storage media, data associated with the second storage policy copy.

Claims

1. A system for sharing a media volume in a network, the system comprising:

a storage manager module executing on a computing device;

a first media management module executing in one or more computer processors communicatively coupled to a media volume and the storage manager module;

a second media management module executing in one or more computer processors communicatively coupled to the media volume and the storage manager module;

wherein the storage manager module is programmed to;

instruct the termination of a first association between the first media management module and the media volume, and

instruct the formation of a second association between the second media management module and the media volume;

shift control of the first media volume from the first media management module to the second media management module by deactivating the first media management module and activating the second media management module wherein the second media management module mounts the media volume and creates an access path to the media volume; and

delegate management of the access path to the second media management module.
