Title: SYSTEM AND METHOD FOR CREATING A SNAPSHOT OF A SUBSET OF A DATABASE
Abstract:
A system for creating a snapshot of a subset of a database that is stored as a plurality of seg-ments in an address space, the system comprising: a determining unit configured to determine from the plurality of segments one or more source segments of the snapshot, and a virtual memory creation unit configured to allocate for the snapshot one or more snapshot segments within the address space, wherein the snapshot segments are mapped to same physical memory addresses as the source segments and wherein the source segments and/or the snapshot seg-ments are set to copy-on-write.
