I'll set up openvpn and switch from pushing to pulling. BTW, is the read-only restriction on the public SSH keys the only advantage of pulling vs. pushing? Are there any drawbacks? In a pull arrangement, if the private keys on the backup server are stolen, the thief would have root read-access on each system? >> I'm backing up to a 1TB USB hard drive dedicated to backups.

Otherwise, it will not. Would it be safe to reserve zero space for root on the USB hard drive?

Would you use rsync or would you have the remote system described above act as a second rdiff-backup server and run the entire backup process a second time? - Grant _______________________________________________ rdiff-backup-users mailing list at [email protected] https://lists.nongnu.org/mailman/listinfo/rdiff-backup-users Wiki URL: http://rdiff-backup.solutionsfirst.com.au/index.php/RdiffBackupWiki
