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.

Abstract: The present disclosure is related to methods, systems, and machine-readable media for log-structured file system management operations. An aggregate amount of over-provisioned computing resources assigned to a plurality of log-structured file system (LFS) objects that are allocated for performance of memory management operations associated with a virtual storage area network (vSAN) can be determined. A subset of LFS objects that are candidates for performance of a particular memory management operation based on an amount of over-provisioned computing resources consumed by one or more LFS objects among the plurality of LFS objects exceeding a resource consumption threshold associated with the determined amount of over-provisioned computing resources assigned to the plurality of LFS objects can be selected. The particular memory management operation using one or more of the candidate LFS objects can be performed.

Abstract: The present disclosure is related to methods, systems, and machine-readable media for supporting clones with consolidated snapshots. A clone of a virtual computing instance can be created in a snapshot tree provided by a software defined data center. A consolidated snapshot including tuples from a diskchain of the clone in the snapshot tree can be created responsive to a determination that the snapshot tree exceeds a threshold.
