BO4 - Dynamic biar file backups?

Hi,

We have a folder and whilst can create and schedule a biar fiel abckup of this, belivee this will only backup the contents to .biar which existed at the time the biar job was created.

What ideally want is to have a scheduled biar job which exports the content of this folder daily to .biar including any reports which were added to it since .biar job created otherwise would need to crate a new job each time reports added to folder.

Is this possible?

Using bo4 sp6.

We have our cms + frs backups in addition to this but the abopve would make restoring indvidual reports easier.

Thanks

Philip
