Abstract
The present disclosure is related to methods, systems, and machine-readable media for cloneless snapshot reversion. A request can be received to revert to a past snapshot of a virtual computing instance in a snapshot chain of a snapshot tree provided by a software defined data center. A live snapshot can be created at an end of the snapshot chain comprising the past snapshot. An intervening snapshot in the snapshot chain can be indicated as abandoned in a snapshot map associated with the snapshot tree based on the reversion.
Claims20
A method, comprising:
- receiving a request to revert to a past snapshot of a virtual computing instance (VCI) in a snapshot chain of a snapshot tree provided by a software defined data center;
- creating a live snapshot at an end of the snapshot chain comprising the past snapshot;
- and
- indicating an intervening snapshot in the snapshot chain as abandoned in a snapshot map associated with the snapshot tree based on the reversion.
A non-transitory machine-readable medium having instructions stored thereon which, when executed by a processor, cause the processor to:
- receive a request to revert to a past snapshot of a virtual computing instance (VCI) in a snapshot chain of a snapshot tree provided by a software defined data center;
- create a live snapshot at an end of the snapshot chain comprising the past snapshot;
- and
- indicate an intervening snapshot in the snapshot chain as abandoned in a snapshot map associated with the snapshot tree based on the reversion.
A system, comprising:
- a reversion engine configured to receive a request to revert to a past snapshot of a virtual computing instance (VCI) in a snapshot chain of a snapshot tree provided by a software defined data center;
- a snapshot engine configured to create a live snapshot at an end of the snapshot chain comprising the past snapshot;
- and
- an abandon engine configured to indicate an intervening snapshot in the snapshot chain as abandoned in a snapshot map associated with the snapshot tree based on the reversion.
Dependencies are inferred from the claim text.
