I am slightly confused about my backup plan and retention rules

Hello, I am new to this website as Macrium directed me here as being a 'free Macrium support forum' so hello to all once again! :) I have Macrium Free version.

I create images of my Seagate 2TB internal harddrive onto my Seagate 2TB external harddrive. Hopefully the image I have added provides viable informataion. (apologies for image size in this thread)

For the first time using Macrium free version, I created a 'Full' image on the 1st June. Straight after I create a 'Diffferential' just after the 'Full' was created. I then proceed to creating Differential images every day. (this was working the past few days)
If I understand correctly, you cannot create a Differential image on the same day as a Full. Thats why you can probably see an error next to the full image (not sure how to fix this? Maybe I have to run the Full again?). I also received an error next to the Differential, but changing the plan days/restarting PC managed to fix then and I was able to successfully create the Differential just now.

Now as I have a 2TB internal creating image onto my 2TB external, there will not be enough space for more than 2 images. I tried this last week and after another full image was created (now 2 in total) my external HD was 90% full. So hope you can advise what plan I should choose, when to run the images and how many days/weeks I should keep them.

What I would like is to create a Differential everyday, and a Full image once a month. Or even better, a differential everyday apart from the day the Full image runs (as you cant do both on same day, even though I did just that the very first time I created both images). Hopefully this can be done?

Apologies if I have gone on for too long, hopefully at the end of this I can have a much better understanding of my plan! :)
Thank you

Hi, just a quick comment- we are volunteers- PC users- who use Windows 10. We strongly recommend disk imaging, and most regular contributors use Macrium. As such, this is peer support, nothing more - we have no ties to Macrium otherwise.

Oh so this was the wrong place to post my question? Or you just mention that you are not related to Macrium at all? I just asked them if they have free forums where I can ask questions and get advice/help. My apologies

Also yes, I have created disk image, just was confused with external hard drive imaging and best may to go about it

You're very welcome to ask the question... and someone will surely help. I was simply explaining the focus of the forum and putting that into context.

Oh ok because I wasconfused for a sec haha. Thanks for clearing that up as I was going to find someone to also ask if this was a place to post such a question, but you have confirmed that for me :)

Official Macrium support is only available to users who buy a licence not the free version. Good job you asked here .

Ye I know, it kinda sucks and I think is somewhat unfair..but its their rules I guess . I am glad this Place is a 'free to ask' forum/community and hopefully I get my issue sorted. It also looks like this website is good for all issues?..sort of a variety website?

Look in the tutorials section - you will not find a better resource in the world!

Yes straight away before I posted this I looked at the Macrium Tut, but I just wanted to get advise/an answer about a plan for my image backup, whilst taking into account my internal and external HD size and what I should do exactly.

I probably should not bump as its only been 4 days. But I have a feeling that with the above comments accumulating to 8 in total, people might presume my question is probably answered, when all it is, is advice about posting :? sorry
