Abstract
A system for managing storage space on an electronic storage medium is provided in which a file format for stored data allows for progressive deletion of low-significance data, for example in a video or audio file, while allowing the remaining portions of the file to be subsequently retrieved. The file format allows for the ready deletion of low-significance data without having to open, edit and subsequently rewrite the data. Furthermore, rules-based algorithms for the deletion of low-significance data allow a user to store and progressively delete such low-significance data in accordance with time parameters, available storage space and the like, without having to delete the full file.
Claims145
A processor-implemented method for managing storage capacity, comprising:
- storing an object in machine-readable format having at least an entire first layer of high significance data and an entire second layer of separately-deletable low-significance data;
- determining via a processor a condition for deleting the entire second layer while retaining the entire first layer;
- determining the extent of the entire second layer in the storage system that the entire second layer is stored in, and
- deleting the entire second layer automatically upon satisfaction of the condition, whereby the object is still accessible by a user through the entire first layer.
An apparatus for managing storage capacity, comprising:
- means for storing an object in machine-readable format having at least a first layer of high-significance data and a second layer of separately-deletable low-significance data;
- means for determining a condition for deleting the second layer while retaining the first layer;
- means for determining the extent of the entire second layer in the storage medium that the entire second layer is stored in, and
- means for deleting the second layer automatically upon satisfaction of the condition, whereby the object is still accessible by a user.
An apparatus for managing storage capacity, comprising:
- a processor;
- and
- a memory in operative communication with the processor, the memory for storing a plurality of processing instructions directing the processor to:
- store an object in machine-readable format having at least an entire first layer of high significance data and an entire second layer of separately-deletable low-significance data;
- recognize a condition for deleting the entire second layer while retaining the entire first layer;
- determine the extent of the entire second layer in the storage system that the entire second layer is stored in, and
- delete the entire second layer automatically upon satisfaction of the condition, whereby the object is still accessible by a user.
A processor-implemented method for managing data storage capacity, comprising:
- storing a plurality of objects in machine readable format having at least an entire first layer of high-significance data and an entire second layer of separately-deletable low-significance data;
- determining via a processor a condition for deleting the entire second layer from each of the plurality of objects while retaining the entire first layer;
- and
- deleting the entire second layer automatically upon satisfaction of the condition, whereby the objects are still accessible by a user.
A computer-readable medium encoded with processing instructions for implementing a method, performed by a computing device, for managing storage capacity, comprising instructions for:
- storing an object in machine-readable format having at least an entire first layer of high significance data and an entire second layer of separately-deletable low-significance data;
- determining a condition for deleting the entire second layer while retaining the entire first layer;
- and
- deleting the entire second layer automatically upon satisfaction of the condition, whereby the object is still accessible by a user.
