restore -i is the command I was using. According to the restore man
page it should be cool to call it with only that flag. Is that not
so? I was trying to restore a couple specific files.

To write the backups I used:
/sbin/dump -0a -f /dev/nrst0 /myfolder/filestodump

I think I can do without the -a flag.

If I didn't specify the blocksize when I did the dump, how do I know
what blocksize to call restore with?
