Claims24
A method of managing virtual disk snapshots comprising:
- utilizing a processor to create multiple disk containers containing multiple snapshots on a host machine persistent memory;
- and
- combining the multiple snapshots on a guest operating system to produce a final snapshot utilized by the guest OS as a virtual disk.
A computer usable program product comprising a persistent computer usable storage medium including computer usable code for use in managing virtual disk snapshots, the computer usable program product comprising code for performing the steps of:
- utilizing a processor to create multiple disk containers containing multiple snapshots on a host machine persistent memory;
- and
- combining the multiple snapshots on a guest operating system to produce a final snapshot utilized by the guest OS as a virtual disk.
A data processing system for managing virtual disk snapshots, the data processing system comprising:
- a processor;
- and
- a persistent memory storing program instructions which when executed by the processor execute the steps of:
- utilizing the processor to create multiple disk containers containing multiple snapshots on the data processing system persistent memory;
- and
- combining the multiple snapshots on a guest operating system to produce a final snapshot utilized by the guest OS as a virtual disk.
