Good afternoon I have a backup routine, and it is set to keep only the last 15 backups, yet it is not deleting the old backups and leaving the recent ones. Can you explain why he keeps retaining old backups?
If, for example, there is only one version of a file left on storage side it will not be deleted since you have the option "always keep the last version" enabled. Most likely that is the case in your setup.
If that is not the case I'd need more info on your config, including screenshots and examples of the files that are not being purged from the backup storage tab.
