The simple answer is no. During the process of destroying a container all backups stored on B2 are deleted at the same time by the server process. This results in us having NO backups as soon as a container is destroyed. The only time we have backups for deleted sites at this time is containers on the OLD dashboard that are from servers we shut down, this we are holding onto until the end of 2024 for any users who did not migrate the container to contact support for the last known backup file.
