Hello @Eugene
The software compression is possible to configure in the Bacula FileSet configuration resource. In Bacularis you can find it here:
[Main menu] => [Page: Director] => [Tab: Configure director] => [SubTab: FileSet] => [Table: Edit FileSet] => [Add Options Block] => [Directive: Compression]
You can see it on the screenshots below.


Best regards,
