True. However, I think retention times and automatic pruning are the 
way to go.

For disk setups, just create two pools - one for full, one for 
incremental backups.

Use "Maximum volume jobs", "Volume use duration" or any othe other 
limiting directives to ensure only one run of backups goes to each volume.

Set the retention times to a bit below 2 months - 58 days or something.

Limit the number of volumes per pool, or pre-create the necessary volumes.

Then, Bacula will automatically recycle the volumes. It will not 
automatically prune or even truncate the incremental volumes depending 
on the pruned full volumes, but it will recycle them when it needs them.
