OK. The essential idea is that the laptop pushes its data to a directory on the backup machine and then triggers the backup machine to incorporate the data into a hard-linked backup, but you have lots of flexibility in how to implement this. If you give me some more information about your requirements, I can suggest an appropriate setup. Specifically: - Are you backing up just your own laptop, or should the setup accommodate multiple machines? - Is it a priority to keep the client script simple? - Does the backup server need to be robust against malicious clients? - Should the data be encrypted as it passes over the network? The important decisions are whether to use ssh, a daemon, or some combination thereof; how to manage the hard-linked backups (I recommend rsnapshot); and what (if any) security measures to put in place on the backup server.
