Correct. If I don't use "verify" ... the backup proceeds normally, but it's corrupt. If I turn on verify, the backup stops when it detects the corruption (somewhere about halfway through). This is with XP using a Samba-shared ZFS filesystem. When XP uses a samba shared UFS filesystem, all is good. Additionally, I tried telling samba _not_ to use mmap() (there's an option), but this didn't fix things.
