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.

Abstract: The invention relates to a computer implemented method for creating a backup of data by a computer system. The creation of the backup comprises: assigning a first memory space in a main memory to data and loading the data into the first memory space; allocating a second memory space in the main memory for acting as container of one or more images of the data in the first memory space; creating the one or more images of the data in the first memory space; and storing the created one or more images in the second memory space and storing a respective copy of at least one of the one or more images in the one or more non-volatile storage media.

Abstract: A mechanism is provided for managing backups. A plurality of logical partitions are generated in a computer system, each logical partition having assigned a respective first portion of the main memory in the computer system as a resource and each logical partition hosting at least one application program which consumes at least a fraction of the first main memory portion of the logical partition. A second portion of the main memory is used as a global memory, the global memory not overlapping with any one of the first main memory portions. For each of the one or more of the logical partitions, one or more images of the first memory portion consumed by the at least one application program hosted by the logical partition are stored as a backup in the global memory.
