This depends on the transfer method: - tar and rsync tunnel their data over ssh -> secure. - rsyncd afair uses its own (simple?) encryption. - smb gives you the usual windows-security -> nill. And as reading the basic docs of backuppc tell you, the server pulls the changes from the clients automatically or when told via the web-interface. > Can the web server reside on a different system than the backup > server? Yes, but the web-interface has to have read-access to the backuppc-filesystem to show you the current state and select files for restore and stuff. If you really must, you can run the daemon and the web-interface on separate machines and nfs-mount /var/lib/backuppc from the daemons machine to the web-server. But there is no real advantage in that, the web-interface isn't used that heavily, its not slowing the daemon down if you run both on the same machine. And you save administration-nightmare when you just run both on the same machine. Have fun, Arnold
