backup retention and backups content

Hi,

I use the latest free version (1.1.89) of Backup Guard on a Multisite, and I read the documentation.

I have an issue with it:

I don’t have “backup retention” setting in the plugin settings, but I would like to set that for recurring backups (for eg always keep five backups, and delete the oldest one).

I only have these settings: Reloads enabled, Show statistics, Exclude paths (separated by commas), Tables to exclude (separated by commas), Number of rows to backup at once, Reload method, AJAX request frequency, Backup destination path

thanks,
Bela
