With the move to Filestore, customers are unable to see which backups were created previously

Summary

Previously, It's possible to navigate to CloudURL/webdav/backupmanager to see which backups have already been created previously. With Filestore, that's no longer possible. This creates a few issues:

1. Only the person that generated the backup are able to download the generated backup (other users will not be able to, they will need to re-generate it again)
2. Another user might wish to generate the backup shortly after that, but instead, is faced with this: "Backup frequency is limited. You can not make another backup right now"
3. Previously usable backup scripts are broken, especially those that automatically downloads the backups from /webdav/backupmanager (which was a much neater way of doing things)
