you have several possibilities: - use the archivehost feature, so last backup of each host can be saved to tape or e.g. destination directory on e.g. external usb drive for offline storage - use rsync to sync the whole pool (usually /var/lib/backuppc) to other hard disk, with special parameters it's possible even over ssh we do our sync of about 2TB in one and a half day over 1gb ethernet to remote location; if possible, do initial sync locally. backuppc service must be shutdown during the sync or at least not doing backups, for consistency. - instead of rsync, if backuppc pool is on btrfs, one could use btrfs' send-receive feature, or e.g. btrbk. didn't try that out, though.
