Idea: backup cadence
Right now, we can select the duration of backups. However, periodic backups with less frequency can go back further for the same amount of data. e.g. what if we could do something like this (in a custom/configurable way, concurrently with each other):
* for the most recent 1 hour, back up all commits separately
* from 1 to 24 hours back from present, back up a snapshot hourly
* back up 1 snapshot per day for the last 30 days
* for the most recent 1 hour, back up all commits separately
* from 1 to 24 hours back from present, back up a snapshot hourly
* back up 1 snapshot per day for the last 30 days
