- If you set root's .rhosts or /etc/hosts.equiv to include the other
- machine, you can use fbackup in machine A to the DAT in machine B
- like this:
-
- fbackup -f machineB:/dev/rmt/0m ...
-
- (substitute correct machine name and device file).
-
- rdump/rrestore should also work, with tar &c you can use a pipe
- through remsh (tar cf - /disk | remsh machineB dd of=/dev/rmt/0m ...
- etc).
