Okay.  So that full is necessary for restoration of data within that
entire time period (3 months).  Depending on the rate of change in your
environment, you might consider cloning the full to prevent a bad day if
a tape fails.

Take the last incremental before a full.  You're specifying that it
needs to be recoverable 2 months after it was made.  If you do that,
then not only does it have to be around, but the Full that supports that
cycle has to be around.  So you'll have about 3 months (total cycle)
plus 2 months (browse) for a total of 5 months in the indexes.

It won't delete the previous full until everything that depends on it
also expires.
