Hi All,

I am using PMS 5.6.34-79.1 and enabled InnoDB changed page tracking.  
Backup Policy is ( Daily 1 Full + Hourly Incremental).

Default value for bitmap file rotation is 100 MB(innodb\_max\_bitmap\_file\_size).  
But I unable to find option to delete older bitmap files, for example, my binlog files expiring in 14 days (in my.cnf =\> expire-logs-days = 14)

Does percona have any such option to delete old bitmap files or any workaround for same?
