I am trying to create a backup to to Google Cloud. I keep getting the message: Deletion of old backups is only supported when a date-based destination is used.
I am confused. There is no end date , date-based for my Google Cloud storage. If I keep paying for 30 years then the storage would still be available??

Please someone help explain

The folder or file name that you save the backups to must contain the date. Use %m-%d-%Y in the folder/file name in the webmin “backup to” location line. Has nothing to do with google cloud.

Thank you for your information. I added what you stated. It accepted the backup settings.
