computer readable program code configured to set an ownership status of the instance of the file on the first storage tier to owned by the user requesting access to the file; and

computer readable program code configured to set an ownership status of an unused instance of the file on the second storage tier from owned by the user requesting access to the file to unowned or owned by a user which previously owned the instance of the file on the first storage tier,

wherein the instances on the first and second storage tiers exist simultaneously.

15. A storage system, comprising:

a first storage tier;

a second storage tier;

logic configured for receiving a request to access a file or instance thereof from a user, wherein the user is associated with an instance of the file on the second storage tier;

logic configured for determining a usage status of each instance of the file on the first storage tier, wherein the usage status includes used and unused;

logic configured for providing the user requesting access to the file with remote access to an instance of the file on the first storage tier having a usage status of unused;

logic configured for transferring an ownership status of the unused instance of the file on the first storage tier from owned by a prior user of the unused instance of the file to owned by the user requesting access to the file; and

logic configured for setting an ownership status of an instance of the file on the second storage tier from owned by the user requesting access to the file to unowned or owned by a second user which previously owned the instance of the file on the first storage tier,
