Abstract

A new approach is proposed that contemplates systems and methods to support authorized access by a second client to files stored on a local content appliances (CA), wherein each content appliance is a storage device/host configured to locally maintain entire or parts of files owned and maintained by a first user. First, a first client agent is configured to establish a region including at least one local CA and to provide authoritative copies of one or more of its files and/or their parts containing sensitive information of the first client to be stored and maintained on the CA in the region instead of uploading them to a cloud storage. The first client agent uploads only metadata of the files to the cloud storage wherein the metadata includes information on storage location and access permission of the files and/or their parts. A second client agent is configured to retrieve the metadata of the files from the cloud storage and to request access to the authoritative copies of the files and/or their parts directly from the local CA in the region based on the retrieved metadata.
