Abstract: Example methods and systems to perform a migration of a virtualized computing instance and its first snapshot hierarchy from a first object store to a second object store have been disclosed. One example method includes identifying a first disk chain of the first snapshot hierarchy having an object running point, identifying a second disk chain of the first snapshot hierarchy different from the first disk chain, and migrating the second disk chain from the first object store to the second object store to form a first branch of a second snapshot hierarchy in the second object store. After the migrating, the example method includes instructing to take a first native snapshot on the object running point in the second object store, instructing to revert the object running point along the first branch and migrating the first disk chain from the first object store to the second object store.

Abstract: A method for implementing native snapshot capabilities on non-native snapshots includes generating a virtual disk container having both native snapshot functionality and functionality of the non-native snapshot, including redo-log snapshot functionality. Redo-log parent disk chains may be preserved, along with subsequent native snapshot data, in virtual disk container objects. A virtual root node of a copy-on-write data structure of a virtual disk container object enables snapshotting and traversal between a redo-log disk chain and a native snapshot disk chain. Throughout backup and reversion operations, the virtual disk container object may be reparented as necessary, and a constant running point may be maintained for the virtual disk container object.
