Abstract: Systems and methods for managing digital assets in a distributed computing environment are described. Meta-data for the digital assets is stored separately from the digital assets. Meta-data for some of the digital assets is copied and stored at a central location. Meta-data for the digital assets is generated by clients of the system. A method of filtering I/O requests of a computer system includes: receiving a plurality of I/O requests from a filter manager of the computer system, the filter manager executing in the system space of an operating system; applying a hierarchical rule set to at least a portion of the plurality of I/O requests by a mini-filter executing in the system space; and providing at least one of the plurality of I/O requests from the mini-filter to an agent executing in user space in response to the application of the hierarchical rule set by the mini-filter.

Abstract: In a system for managing digital assets in a distributed computing environment, meta-data for the digital assets is generated by clients of the system and stored separately from the digital assets, such as at a central location. A computer system operating under control of an operating system performs categorization of the digital assets using an agent operating in user space of the computer system. The agent receives an I/O request identifying a digital asset and applies categorization information to the identified digital asset based on the received I/O request without intervention by an end-user of the computer system, and the categorization information is stored as part of an asset identification tag associated with the digital asset.

A method of categorizing digital assets of a computer system, the computer system operating under control of an operating system that generates input-output (I/O) requests includes: receiving, by an agent operating in user space of a computer system, an I/O request identifying a digital asset; applying, by the agent without intervention by an end-user of the computer system, categorization information to the identified digital asset based on the received I/O request; and storing the categorization information as part of an asset identification tag associated with the digital asset.

Abstract: In a computing system having a plurality of storage devices, notification of an application program of a change of state in a storage device so that corrective action can be taken. A notification module creates and maintains an event queue for storing events corresponding to changes in the state of the storage devices. The notification module indicates to the application programs that events are in the queue. The queue conditions are monitored by the notification for queue maintenance.
