Unfortunately no, but that would be a good solution.  I only do full backups of
the databse.  Any other ideas??

Scott,

are you doing incremental DB backups?  One possibility is the fact that all the
backups in a series (full followed by a number of incrementals but not the
following
full) have to expire as a group (I think) so perhaps the ones that were in vault
status two days ago were really 11 days old but not allowed out of vault status
until a day ago when a new full was done.  Then today the del volh tramples on
the
volume that is 12 days old.

Note: I am speculating and have actually confirmed  the details of the behavious
I
am speculating on.

Interesting problem, though...
