Limiting the reported disksize for Time Machine does not work with new "backupbundle" macOS 10.5 (Catalina) started to use ".backupbundle" instead of ".sparsebundle" for Time Machine backups. Thus the calculation via "fruit:time machine max size" does not work anymore. When creating a symlink directly in the volume path. For instance "ln -s file.backupbundle file.sparsebundle“ calculation is working again. So I guess that a simple extension of the search string from just "sparsebundle" to "sparsebundle" OR "backupbundle" should be enough vfs_fruit.c But I think it's in this line: <https://github.com/samba-team/samba/blob/c68133d41c368c52cd5ac3c34dbe888ceccd7619/source3/modules/vfs_fruit.c#L4909>
