We have a SLA to have a 90 day history of versions on files/folders.
I had been in the practice of retaining 14 weeklies, and 14 dailies, but we are concerned that if there was a unique change, on say, 25 days ago that was needed, would it be captured in the weeklies? To put it more concretely, for example, if 25 days ago (on a Tuesday), I write new data, then 24 days ago (the day after, Wednesday) I delete it. Will that file show up in any of the weeklies?
Just for confirmation, the dailies are a separate set of deltas from the weeklies right?
A separate question: In theory, doing 14 weeklies with 14 dailies would use less space than 90 dailies right? but if my scenario mentioned above doesn’t capture that deleted file, I will have no choice but to do 90 dailies.
