Yes, it looks like it continues and flexbackup "fails" at the end. Nothing
is written to the backup directory and the log is not compressed. (I *do*
have it set up to compress the log, which seems to happen if the backup is
successful.)

The thing is that these files don't change, they disappear. In that case, at
least, flexbackup really shouldn't care, and should just treat it as if the
file was never there in the first place. IMO...
