Full, Incremental and differentail backups

Okay, I was trying to ask this question before but i guess asked it in the wrong way. We have CA Archserve and i am being told there is a way to set an incremental backup so this it will do this. In the given scanrio we have several 100 GB hard disk that backup the server daily we also have on 70 GB rev drive. We will be backing up everything to the external disk and doing a monthly rev backup. Anyways I am being told that we can make the backups run so that we have the same backup doin incrementals which will save a copy of both the changed file and the old file and we can extract it from those backups without changing the media. in other words we can leave the same media conntected to the machine and have it backup incremental until we needs something. Say someone says they deleated something 13 days agao and this media has been running the same incremental backup. According to what i am being told we can open arch serve and go back 13 days it will look at the media which has the backup on it and go back 13 days allowing us to retieve the file. I was under the influence that the change would be the file deleation and the incremental would remove the file.

To Apply these in ARCserve -

Open ARCserve system manager
If you are editing an existing job select "Job Status" Select the job > Right Click it  > And select Modify Job > Select the Scheduling Tab
If you are creating a new job Select "Backup" set the backup you require then select the scheduling tab.
On the Scheduling In the "Repeat Method" Change it to days of the week > Select the days you want the job to run.
Below this You can set the option of Full-Keep the archive bit (This is the same as copy which I mentioned earlier), Full Clear the archive bit (This is a true full backup), Incremental or Differential.

Using this you can set a Full backup (clear the archive bit) on a Monday then an Incremental (or differential) job to run on Tuesday through to Friday for example
