Limit number of kobo-docker backups

Hi team,

We have kobo-docker on a long-running server with weekly backups turned on, saving locally. The server frequently runs out of disk space sometimes at important times, so I have to manually go in and delete the backups via the terminal, which is not ideal.

I know you can customise the backup frequency but is there any way to configure a limit on the number of backups? E.g. a maximum backup retention time?

Thanks
