Backup Management for a Plurality of Logical Partitions
First Claim
1. A computer implemented method for managing backups, the method comprising:
- generating a plurality of logical partitions in a computer system, each logical partition having assigned a respective first portion of a main memory in the computer system as a resource, 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;
using a second portion of the main memory as a global memory, the global memory not overlapping with any one of the first main memory portions; and
for each of the one or more of the logical partitions, storing one or more images of the first memory portion consumed by the at least one application program hosted by the logical partition as a backup in the global memory.

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.

14. A computer system comprising:
-
one or more processors; and a main memory comprising a global memory, wherein the main memory comprises instructions which, when executed by the one or more processors, causes the one or more processors to; generate a plurality of logical partitions in the computer system, each logical partition having assigned a respective first portion of the main memory as a resource, each logical partition having assigned one or more of the one or more processors as a resource, 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; use a second portion of the main memory as the global memory, the global memory not overlapping with any one of the first main memory portions; and for each of the one or more of the logical partitions, store one or more images of the first memory portion consumed by the at least one application program hosted by the logical partition as a backup in the global memory. - View Dependent Claims (15, 19, 20)
