- This abstract for appeared for US patent application number 18342581 Titled 'INCREMENTAL VAULT TO OBJECT STORE'
Simplified Explanation
The abstract describes a method for handling changes in a data volume. When a chunk of data in a current version of the data volume is changed, the method creates a block of data representing the changed chunk and stores it in an object store. The object store also stores previous versions of the data volume. The method then updates the corresponding entry in the index stored on the object store with the new data. Finally, the method deletes any blocks of data from the object store that are no longer associated with an entry in any index.
