I was about to purchase the software where I realized. The Auto Delete of Backups in based on dates rather than or including retaining the last “x” backup files instead. If a machine has a bad time stamp it could incur data loss, so keeping it based on the number of files in my opinion is better. I would write a script for that, but the native tool does not even allow me to disable “Auto Delete”.
I only want to delete old backups after there is at least “x” number of backups in the folder.
The good news is that this feature is planned for the new version of SqlBak, which is currently in development. It will allow exactly what you’re describing — keeping a specific number of recent backups regardless of timestamp.
Aside from that, unfortunately, the current version doesn’t support applying deletion logic based on file count.
