Abstract
A method and system for intercepting file system writes. When intercept processing is enabled, a file write request may be passed to intercept write processing, prior to normal write processing. Intercept write processing may include: identifying the file, copying original file information, modifying the write pointer within the original file information, storing the intercepted write in a cache using the modified write pointer. The intercepted write may be allowed to complete normal processing after the intercepted writes are stored in the cache. The intercepted writes may then be retrieved from the cache (e.g., in first-in-first-out (FIFO) order, or in some other user-specified order).
Claims15
A method of data storage and retrieval in a computer system, the method comprising:
- registering one or more files with an intercept software component technology, wherein said registering is performed using a first software utility;
- the intercept software component technology intercepting writes to the one or more registered files;
- storing the intercepted writes to the one or more registered files in a cache;
- the first software utility retrieving the intercepted writes to the one or more registered files from the cache in a particular order.
A method of data storage in a first computer system, the method comprising:
- registering one or more files with an intercept software component technology, wherein said registering is performed using a first software utility;
- the intercept software component technology intercepting writes to the one or more registered files;
- storing data from the intercepted writes to the one or more registered files in a cache;
- the intercepted writes to the one or more registered files completing normal processing, after the intercepted writes are stored in the cache;
- the first software utility requesting data from one or more of the intercepted writes to the one or more registered files from the cache.
A method of intercepting writes to one or more files in a computer system, the method comprising:
- finding one or more file identifiers associated with the one or more files;
- storing a copy of original information related to each file identifier wherein the copy of the original information related to each file identifier comprises a write pointer;
- modifying the write pointer within the original information related to each file identifier;
- storing the intercepted write to the one or more files in a cache using the modified write pointer;
- allowing the intercepted write to the one or more files to complete normal processing after the intercepted writes are stored in the cache.
