Abstract
A snapshot management method includes detecting a change in a configuration of a virtual machine; recording, in a storage unit, a snapshot of a file system of the virtual machine when the change in the configuration is detected; and determining a stable operation of the virtual machine by monitoring an operation status of the virtual machine and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition.
Claims13
A snapshot management method executed by a computer, the snapshot management method comprising:
- detecting a change in a configuration of a virtual machine;
- recording, in a storage unit, a snapshot of a file system of the virtual machine when the change in the configuration is detected;
- and
- determining a stable operation of the virtual machine by monitoring an operation status of the virtual machine after the virtual machine has been rebooted, and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition to prevent the last recorded snapshot from being saved.
A snapshot management apparatus comprising:
- a configuration change detection unit that detects a change in a configuration of a virtual machine;
- a snapshot recording unit that records, in a storage unit, a snapshot of a file system of the virtual machine when the change in the configuration is detected;
- and
- a stable operation determining unit that determines a stable operation of the virtual machine by monitoring an operation status of the virtual machine after the virtual machine has been rebooted, and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition to prevent the last recorded snapshot from being saved.
A snapshot management apparatus comprising:
- a processor to detect a change in a configuration of a virtual machine, to record, in a storage unit, a snapshot of a file system of the virtual machine when the change in the configuration is detected, and to determine a stable operation of the virtual machine by monitoring an operation status of the virtual machine after the virtual machine has been rebooted, and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition to prevent the last recorded snapshot from being saved.
A computer-readable, non-transitory medium storing a program that causes a computer to execute a method comprising:
- detecting a change in a configuration of a virtual machine;
- recording, in a storage unit, a snapshot of a file system of the virtual machine when the change in the configuration is detected;
- and
- determining a stable operation of the virtual machine by monitoring an operation status of the virtual machine after the virtual machine has been rebooted, and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition to prevent the last recorded snapshot from being saved.
