When a volume gets recycled the volume gets overwritten in the next
backup that uses it. I think now you can have it automatically
truncate if you want.

No definitely not that.

Bacula does not have that feature. Also remember that recycling is an
entire volume at once not parts of the volume get deleted over time.
Bacula volumes are append only then delete the entire volume to
recycle. The reason for this is bacula supports tape and other formats
not just disk and all formats work the same way.

Bacula does not work this way. And because of my answers above I am
not sure you could force it do do what you want.
