Hello, I am answering this because I suspect that there are a number of users doing things similar to what you want and what you are doing. Unfortunately what you are doing and what you are proposing is unoptimized and probably wastes a lot of space on your disk thus limiting the length of time that your backups could be retained were schedules/retention periods opitimized better.
Without going into details, and without looking at your situation in detail, you probably should be doing a Full backup monthly, a Differential weekly and Incrementals daily. This, of course, depends on your precise needs. If you read the chapter in the development manual entitled "Using Pools to Manage Volumes": http://www.bacula.org/dev-manual/Using_Pools_Manage_Volumes.html you will find a *real-live* case where the requirements that were given me were probably similar to yours and what a lot of others need. I explain how to make calculations on data volumes and what directives to use. This system has now been in production since January 2004 and has worked without intervention on my part. In fact, it has worked so well, that it is still running version 1.34 (other than one Bacula upgrade if I remember right and the addition of a harddisk due to their growing data requirements), and hence the FileSet given in the example is no longer correct because of the change from old style Includes to new ones in 1.36.3. I will be updating the site over this weekend to 1.36.3, then a few weeks later to 1.37 (I do that to avoid two simultaneous database upgrades to simplify any possible problem resolution). One main motivation for upgrading is to be able to correct the example in the manual with a *real* conf file that is in use :-) The chapter entitled "Basic Volume Management" gives more of the details behind the above real-life example.
