I'm confused about how the VERSIONS DATA DELETED paramater works.

If the backup copy group specifies

Versions Data Exists 30
Versions Data Deleted 1
Retain Extra Versions 30
Retain Only Version 30

And the following takes place

6/29/99 file dave.oracle.dump.Tue is created and bound to this mgmt_class,
        during the nightly incremental.
6/30/99 file dave.oracle.dump.Tue is deleted.
7/6/99  file dave.oracle.dump.Tue is created again and bound to this
mgmt_class,
        during the nightly incremental.

     What will be the availability of the file created on 6/29?
