EXPRESS-FULL BACKUP OF A CLUSTER SHARED VIRTUAL MACHINE |
摘要 |
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. |
