Incremental backups

Same as Full Backup script with the following exception.
ORA_FULL=1 to ORA_FULL=0
and 
ORA_INCR=0 to ORA_INCR=1


See portion of script below

#     schedule type is                BACKUP_TYPE is
#     ----------------                --------------
# Automatic Full                     INCREMENTAL LEVEL=0
# Automatic Differential Incremental INCREMENTAL LEVEL=1
# Automatic Cumulative Incremental   INCREMENTAL LEVEL=1 CUMULATIVE
#
# Note that we use incremental level 0 to specify full backups.
# That is because, although they are identical in content, only
# the incremental level 0 backup can have incremental backups of
# level > 0 applied to it.
