Data stream filters and plug-ins for storage managers
First Claim
1. A storage manager system configured to manage client data on a data storage resource, comprising:
- a data processing core;
a first communication interface to an application;
a second communication interface to a data storage resource;
a filter identification interface configured to receive an identification of a data stream filter that is not part of said storage manager and does not require application or storage manager domain knowledge;
a filter identification store configured to maintain said identification of said filter;
a filter invocation subsystem configured to invoke said filter as part of a requested data stream operation;
a data stream receiver configured to receive a data stream from a data stream source representing one of said application or said data storage resource;
a filter writer configured to provide said data stream to said filter;
a filter reader configured to receive said data stream from said filter following filtering thereof; and
a data stream sender configured to send said data stream to a data stream destination representing one of said application or said data storage resource that is not said data stream source.

Abstract
A storage manager and related method and computer program product manages client data on a data storage resource and includes the ability to utilize many different types of data stream filters that are neither built into the storage manager nor require a custom programming effort. A storage manager user may readily implement filtering by simply identifying a data stream filter the user wishes the storage manager to use for filtering the user'"'"'s data. The filter can be an off-the-shelf program that is not part of the storage manager and which does not require client application or storage manager domain knowledge (e.g., knowledge of protocols or data types or formats used by the application or storage manager). The storage manager invokes the identified filter as part of a requested data stream operation and receives a data stream from a data stream source. The data stream is provided to the filter, which filters the data stream. Following filtering, the storage manager receives the data stream from the filter and sends it to a data stream destination.

11. A storage manager method for managing client data on a data storage resource with data stream filtering on behalf of a remote client, comprising:
-
implementing a storage manager system, comprising; a data processing core; a first communication interface to said remote client; a second communication interface to a data storage resource; one of a filter receiving interface or a filter identification interface respectively configured to receive a data stream filter or an identification of a data stream filter that is not part of said storage manager and does not require client application or storage manager domain knowledge; a filter invocation subsystem configured to invoke said filter; a data stream receiver configured to receive a data stream from a data stream source; a filter writer configured to provide said data stream to said filter; a filter reader configured to receive said data stream from said filter following filtering thereof; and a data stream sender configured to send said data stream to a data stream destination; implementing a filter store configured to maintain said filter or an identification of said filter and which is accessible by said storage manager system; and receiving said filter or an identification of said filter from said remote client or a location specified by said remote client; receiving a data stream from a data stream source that is either an application associated with said remote client or said data storage resource; providing said data stream to said filter; and receiving said data stream from said filter following filtering thereof and sending said data stream to a data stream destination that is either said remote client application or said data storage resource. - View Dependent Claims (12, 13, 14)
