Hello JJ,
In this scenario I would recommend the following:
1) Create a Backup To Disk folder (B2D) on the Disk using the technote " http://www.symantec.com/docs/TECH77762 "
2) Create 2 media sets and named them as FULL and DIFFERENTIAL
3) Set the Overwrite Protection Period of FULL Media set as 6 days
4) Set the Overwrite Protection Period of DIFFERENTIAL Media set as 6 days
5) Create two backup jobs using the same selections (FULL backup and DIFFERENTIAL backup)
6) Schedule the FULL backup to run on any one day of the week (usually weeekends)
7) In the FULL backup properties select the destination device as B2D and select the Media set as FULL Media set
8) Schedule the DIFFERENTIAL backup to run on all days other than the Full backup day
9) In the DIFFERENTIAL backup properties select the destination device as B2D and select the Media set as DIFFERENTIAL Media set
Explanation: What this setup will do is during the Full backup it will backup all your data on the Disk. Then in the Differential backup it will backup only the changed data from last full backup set. When the Full backup will run it will be keep the backup file for 6 days after which it will overwrite during the next full backup job. This will help to reclaim (reuse) the space on the drive and the drive not get full
During the Differential backup it will backup the data which is changed from last Full backup. And as the Overwrite Protection is set to 1 day it will keep the backup file for one day and will overwrite during the next diffrential and again this will help is reclaiming the space on the disk which will avoid the disk to get full at any given time.
Thanks,
