Agree, 1 MB is basically nothing on a tape and it can accommodate easily a huge amount of bsr files.
My /etc/bacula is 88k uncompressed.

not necessarily if you make this information at the beginning of the tape look like a "volume file".
It will be ignored by old directors because it will look the same as a failed job that took space on the tape.

Or you could just decide that backward compatibility of that type is just not that important. For instance: versions x.0.0 and later use this format. Tapes written in this format are not accessible to older versions. It's OK to do that. It's also OK to have the option of writing in the older format from the newer directors. This will give you time to bring all your directors up to date before switching to the new format.
