This is generally an unmounted filesystem, although I don't see why it couldn't be a readonly filesystem. The way dump and restore work, they generate a map of all files and directories at the beginning of the dump process, and the backup is done from that map. Hence, files that were there at the time the dump was begun might not be there if the filesystem is writable. Thus, you might see some files in the table of contents that are not actually on the tape. And it is possible that new files were generated after the map was done that will be on neither the tape nor the table of contents. Check the names of the missing files. Is it possible they are just temporary files being generated by an application? -- Jonathan Fosburgh Software Systems Specialist III MD Anderson Cancer Center Houston, TX Home Page: http://www.fosburgh.org Manager, FreeBSD Webring: http://www.fosburgh.org/computer/freebsdring.html ICQ: 32742908 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
