Thanks again Roland,
I think I must have lost those files when fsck_ffs did its salvage operation

The expected files were 
/disk02/bkup/dump/ad0s1a-090909.dump
/disk02/bkup/dump/ad0s1e-090909.dump
/disk02/bkup/dump/ad0s1f-090909.dump


fls from the image file => listfile

# sed -n 30153,30158p list
d/d 4804608:    bkup
d/d 918528:     servers
+ d/d 918529:   apache
++ d/d 918530:  httpd-2.0.40
+++ d/d 918531: os
++++ d/d 918532:        os2

Shows the bkup directory but no subdirectory (i.e ../dump/. or dumpfiles

Now, if perchance these files were found with fls what would have been the
method to extract them back and make them readable to the file system.

Thanks
