Is there any chance that the veritas backup agent on linux is somehow
locking the files as root against read or some other such insanity? If
so, I'd imagine there being problems of some kind. But I have no idea if
the veritas backup agent can or does do something like that.
Either way, I'd turn off file system backups for that directory, as they
aren't gonna do any good anyway.
I'm thinking with my rusty old windows NT sysadmin hat here, by the way.
