I'm using dump for a "safety net" backup to a remote solaris scsi tape. I seem to have the dump command working okay using:
/sbin/rdump -0u -L linuxfoo-opt -z -f sunbar:/dev/rmt/0c /opt
I can't seem to figure out how to use the restore command in the same way. I assume I'm missing something painfully obvious, since it would be incredibly stupid to create a backup command capable of backing up to a remote system with no way to restore from it.
