Create a rolling merge action that:
Keeps most recent 1 day
14 Day layers
After that, what you keep, how often, and how long is up to you.
The "Keep most recent" setting basically ignores any layers created in that time period. So keeping 1 day will leave your last 24 hour's worth of captures alone.[*]
The "14 day layers" create 14 one-day time periods following what you keep. All of the layers within each time period (day) are then merged into a single layer, keeping only the last version of each file.
The logic repeats using successive periods of weeks, months, and years.
PS: I did a test full recovery to a temporary partition and it booted flawlessly!
Always good to know.
[*] Footnote: The rolling merge time periods are always calculated relative to midnight the morning of the day you run the merge (i.e. 00:00:01). So running a merge at 1:00 AM and 11:59 PM has the same effect. It also implies that any captures done between midnight and now are always ignored, since the ignore period always starts at the last midnight.
