    Question about macrium's retention policy, im a bit shakey


    Incredible how hard it is to find solid recommendations revolving around certain criteria online for macrium lol.

    Anyhow, here is what i have, and what im going for.

    I want grandfather-father-son and I want 3 months worth of full backups. 1 month worth of differential. 2 weeks worth of incremental.

    trying to keep the overlap/consolidation to a minimum as that seems to take some time.

    This was easily defined with setting the retention rules based on time, but i realized the caveat there. If your pc goes down for a length of time, or your not on it for a stretch due to life's curveballs or something, macrium pays no attention and will start offing your backup sets.

    So i want to change it to keep xx number of backups instead. Much safer.

    Again, 3 full backups is the easy one as theyre taken once a month. Its the differential and incremental I get shaky on.

    Differential are once a week, but obviously not the week you do full backups. So would I want to retain 3? or 4? (since some months have 5 weeks?

    Moreso, incrementals. Those are set for daily. Do i want two weeks worth to be set to 14 and macrium ignores the ones that fall on a differential day? Or would that give me two weeks and two days worth?

    aka do i want
    full 3
    differential 4
    incremental 14

    or do i want
    full 3
    differential 3
    incremental 12

    disappointed in how slow ive become in old age, this should not be so perplexing to me >.<

    Offhand, wondering why you need daily incrementals and how you arrived at "I want grandfather-father-son and I want 3 months worth of full backups. 1 month worth of differential. 2 weeks worth of incremental."?

    Are you relying on Macrium for data backup as well as Windows system backup?

    Does your Windows installation undergo significant changes on a daily basis?

    You pretty much nailed it. I'm always working on the pc. I tend to do sketchy things within the registry and im very anal about keeping this install solid and going as it has years of work gone into everything on it, softwares, settings, customizations etc.

    Ive been bitten many a time in the past and had to roll back way further and lost days of work or worse.

    With limited space for backups, I want to be able to roll back any day for the last 2 weeks, or any week for the last month. and if im curious and want to browse an old image, or some issue that escaped my realization cropped up, i have a full for the 2 months prior.

    thats my thinking on it anyhow.
