It could be something as simple as CreateProcess having nowhere to put the
verbose output. Try adding the switch
-y D:\SiteData\007222\Backup\007222_SiteData4_DL1.log

to the end of the whole command and see whether that fixes it.

btw, you just caused me to discover an error in the gbak switches list in
The Book. the -v switch abbreviates -verify, not -verbose. But gbak
doesn't mind, it seems to ignore everything after the "v". I'd suggest
either correcting "-verbose" to "-verify" anyway. Though it's a far call,
you never know but what someone might decide to add another switch like
"-verbs_only" at some future point.
