Abstract

An in-memory application has a state is associated with data (CA0, CB0, CC0) stored in a memory and accessed by the application. A first restore point of the application is determined to represent a first time point (T0) in the execution time associated with a first state at which the application accesses the data being stored in memory locations (CA0) using first addresses (S1) and first pointers (A0) which are stored in a first data structure. A first restore point identifier is assigned to the first restore point, whose value is indicative of (T0). The first restore point identifier is stored in association with (A0) and (S1) in a first entry of a second data structure. In the first data structure, the first addresses (S1) are associated to second pointers (A1) to contents of memory locations (CA1) in the memory, and redirecting writing operations.
