Abstract: A system is provided for migrating, in an automated way, old backups created using older software to the current vendor. Generally, backup products are composed of a few broad sub-systems. The migration system organizes old backup data and can present the backup data to a new vendor's system. The embodiments include a virtual appliance, which can include a client (e.g., a consumer of the XBSA API) to drive the legacy vendor with user selections to pull data from existing media and create a server personality that can be presented to the new backup software. The new backup system can then use existing means to discover, backup, and catalog data made available via the virtual appliance.

Abstract: A system manages a file directory containing data that is exposed by a file-server. The system provides a block-device layered on top of a network share that treats the underlying network share as read-only but allows local file-system semantics to operate on top of the network share. The end-result is a virtual disk containing a locally recognizable file-system that can read and write from the perspective of the operating system but where the data is store in the cloud as network shares. The virtual disk appears to be a fully functional local disk with all the expected local disk semantics.
