Abstract: Presented herein are systems and methods for backing up and restoring data from a client computing system to a provider's virtual tape library using a proxy. The proxy emulates a physical tape library that interfaces with a client's system and allowing the use of client's native tape backup commands to initiate the backup data process. The backup data is transferred into files that represent tapes in the proxy and further processed into extents in the provider's object store. The processed backup data is stored in the local cache in the object store where it is retained for future access. The backup data may also be transferred to long-term storage via a media agent that facilitate movement of the data from the local cache to secondary storage. The present disclosure also provides for creating auxiliary copies of the backed-up data using a second VTL at a second site.
