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.
