The invention discloses a memory snapshot data acquisition method, which comprises the steps of adding a snapshot identifier to a corresponding physical memory page according to received mark information to obtain a to-be-snapshot memory page added with the snapshot identifier; when the memory is triggered to be abnormal or crashed, determining all to-be-snapshot memory pages according to the snapshot identifier; carrying out snapshot processing on all the to-be-snapshot memory pages to obtain memory snapshot data. By adding the corresponding snapshot identifier to the physical memory page inthe snapshot data, only part of the physical memory page is subjected to snapshot data backup, so that the data volume of the memory snapshot data is reduced, and the snapshot efficiency of the memorydata is improved. The invention further discloses a memory snapshot data acquisition device, a server and a computer readable storage medium, which have the above beneficial effects. 本申请公开了一种内存快照数据获取方法，包括：根据接收到的标记信息对对应的物理内存页添
