Sure, specify the "no-rewind" device (e.g., /etc/nrsa0 for a SCSI tape) as the device for the backup output, like dump -0 -f /dev/nrsa0 / dump -0 -f /dev/nrsa0 /usr mt -f /dev/nrsa0 rewind An end-of-file mark is written to the tape each time its device is closed to separate each file on the tape. The restore command has an option to specify the number of files to skip on the tape, so you can forward to the dump for a particular filesystem when you need to restore files. See the dump(8), restore(8), sa(4), and mt(1) man pages for more details.
