Grandfather, father, son backup strategy using removable hard drive media
For the grandfather father son... you need just configure your backups as stages of the same job and set them to start at the same time... B.E. will supersede the job that runs more frequently ... for example if you had a job with a stage that ran daily at 8:00 pm, a stage that ran weekly at 8:00 pm and a stage that ran monthly at 8:00pm. the daily job would run until the weekly came up..it would be superseded by the weekly then when the monthly job comes up both the weekly and daily would be superseded by the monthly ... The article that you referenced written by TA PKH is awesome... Configure your storage pool and target it for the job... Note that in order to perform the restore B.E. Will need access to all backups in the chain which would include the full and all subsequent incrementals which would be spanning multiple drives.
If you want to rotate your disks in the manner you proposed, then you need to ensure that Disks 1 - 3 are plugged in and online whenever you are trying to restore anything involving the incremental backups.
