Differential Scheme
Probably qiute a simple question on backup schemes, but I really struggle to understand the documentation. I want to use a Differential backup scheme, where I run a Full Backup every week and a Differential every day and retain a rolling two week history. So what I want to end up with is this;
After week 1
F1 d01 d02 d03 d04 d05 d06
After week 2
F1 d01 d02 d03 d04 d05 d06 F2 d07 d08 d09 d10 d11 d12
After week 3
F2 d07 d08 d09 d10 d11 d12 F3 d13 d14 d15 d16 d17 d18
After week 4
F3 d13 d14 d15 d16 d17 d18 F4 d19 d20 d21 d22 d23 d34
etc.
How do I accomplish this?

Well, no backup scheme works the way you described.
I can give you something very close to what you want. I am using this set up for my backups and it will retain a Full Backup for 2 weeks and create a differential backup every day. What it won't do is keep a full 2 week set of differentials.
Here's what I have:
I start by selecting System Backup for type.
In schedule, under General, I have it run one backup each day at 0100. Under Advanced, I tell it to do a differential backup.
Under scheme (Pro version only), I enable backup management. Specify Differential Backup and tell it to keep the last 7 versions.
What this gives me is a Full Backup once a week where it keeps 7 versions. 2 of them are Full backup sets and 5 are differential sets. Every day when a new differential is created, the oldest diffential backup set is deleted (deletions start after 7 sets are created). When it gets to day 7, the oldest Full Backup set is deleted and new Full Backup set is created.
I hope this will help you.
Thanks for this.
