Hi Andrew,
Thanks for the forum post.
The
option to maintain the last backups is available only with
PostgreSQL and MySQL database. We believe you are using MS-SQL
database. For MS-SQL database we use the native MS-SQL backup
methods for creating backups. Since, it is native SQL method and
you have an option to delete the old backup from SQL. Please refer
this link for the same.
Please try the same and let us know how it goes.
Thanks & Regards,
Chris
