Abstract

A computer having backup capabilities for backing up data on a host storage disk of the computer to a remote archive repository, the computer including a backup application that determines when data to be backed up should be copied to the remote archive repository and makes read requests to make a copy of data on the host storage disk and makes write requests to store the copy at the remote archive repository, the computer also including a backup system that receives the write requests and the copy of data and has a remote procedure call interface for transmitting the data to the remote archive repository.
