1. 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 and deleting, from the storage unit, the last recorded snapshot for the virtual machine when the operation status satisfies a predetermined condition.

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.
