Abstract
The efficient backing up of a hierarchical system in cloud blob storage. The hierarchical structure of the system as it existed at a prior instance in time is reconstructed. A change journal that represents changes in the file system that prior instant in time is then used to formulate an updated file system hierarchy as it exists at a second instant in time. An updated injected representation of the file system, and updated file system reversal information is then formulated and provided to cloud blob storage. The injected representation of the file system is a one-to-one function of the content of the file system, in that the reversal information can be used to recover the content of the file system. Injected representations of various nodes in the system hierarchy may also be remotely stored.
