Ghost 14, Disk-Based Backup, & "Limit Recovery Point Sets" Option

Hello:

 

I want to limit my disk-based backup to three (3) recovery point sets.  I start new recovery point bases (Full Backups) on Monday, Wednesday, and Friday, with incremental backups on the remaining days, Sunday, Tuesday, Thursday, and Saturday.  I have the "limit recovery point sets" option set at "3" and all backups are being created, properly, with an exception.  Starting with zero recovery point sets, I would anticipate that after having all backups created, properly from Monday through Sunday, that starting with the second Monday, the previous Monday's recovery point set (Full Backup) would be replaced with the second Monday's backup or the new recovery point set.  But, this isn't happening and since my backup drive has limited space, only an incremental backup is being created on the second Monday and the Ghost log states that the scheduled backup could not complete, as there wasn't enough space on the backup drive and that the process has been cancelled by the user.  What am I doing, incorrectly, that is keeping the second Monday's new recovery point set (Full Backup) from being created and replacing the first Monday's recovery point set?  Am I misunderstanding something, regarding the "limit recovery point sets" option and/or another setting?  Finally, LiveUpdate has been engaged and Ghost 14 is completely updated.

 

Thank you for your assistance.

 

Sincerely,
