This may not be a 'silent' error; you're not recording the output.

When you manually issue a backup, are you running 'vos backup' ? Try
running 'vos backupsys' with the prefix set such that it only backs up
that one volume, and see if that makes a difference.
Alternatively, you can make the cron job save stdout/stderr somewhere,
and examine it after you notice that this has occurred.
