The present invention is a method of managing data in an encrypted system comprising a backup server and a client device having a first remote storage medium, the client device and backup server being configured to exchange encrypted communications with one another, the method comprising: receiving, at the client device, a request to backup data from the first remote storage medium to the backup server; in response to receiving the request, initiating a backup routine at the client device, the backup routine comprising: identifying a first set of files stored on the first remote storage medium; generating, at the client device, a cryptographic signature value for each file in the first set of files, wherein the cryptographic signature value is computed by using actual data of the file as an input to a cryptographic signature generating algorithm which computes the cryptographic signature value; generating a first inventory including the cryptographic signature values calculated for the first set of files; transmitting the first inventory from the client device to the backup server via one or more encrypted communications; and causing one or more files from the first set of files to be transmitted to the backup server for storage by the backup server.
