Patent ID: 7694097

Claim:
A method of managing a constrained storage space within a storage volume having a fixed size and a plurality of users, the method comprising: assigning, for each of the users, a user-specific threshold to the constrained storage space to define for the user an amount of data that is less than a dynamically reconfigurable storage capacity of the constrained storage space, the dynamically reconfigurable storage capacity being less than the fixed size of the storage volume; comparing, for each of the users, an amount of data to be stored in the constrained storage space and the respective user-specific threshold; and performing, for each of the users, a user-specific action predefined by the user and executed when the respective comparison indicates that the amount of data to be stored in the constrained storage space would cause a transition of the respective user-specific threshold, the user-specific action being different from a default action to be performed for each of the users in the absence of a respective user-specific action, the user-specific action for one of the users comprising deleting preexisting data in the constrained storage space and the user-specific action for another one of the users comprising changing a size of the constrained storage space.
