Abstract: A computer-implemented method includes creating a first snapshot of at least one virtual machine at a first time. The first snapshot is created at a computing device of a cluster of computing devices configured to share the at least one virtual machine. As an example, each computing device in the cluster may modify the shared virtual machine via a direct input/output (I/O) transaction, bypassing a file-system stack. The first snapshot is transmitted to a backup device. The method includes creating a second snapshot of the at least one virtual machine at a second time and determining a set of changed data blocks associated with a difference between the second snapshot and the first snapshot. The set of changed blocks is transmitted to the backup device.

Abstract translation: 计算机实现的方法包括在第一时间创建至少一个虚拟机的第一快照。 第一快照是在被配置为共享至少一个虚拟机的计算设备集群的计算设备上创建的。 作为示例，集群中的每个计算设备可以通过直接输入/输出（I / O）事务来绕过文件系统堆栈来修改共享虚拟机。 第一个快照被传送到备份设备。 该方法包括在第二时间创建所述至少一个虚拟机的第二快照，并且确定与第二快照和第一快照之间的差异相关联的一组改变的数据块。 更改的块的集合被传送到备份设备。
