Cadence of backups

[Truncated]

Due to a number of reasons, our group is playing every 1-3 weeks in a very irregular basis. I like to have half-hourly backups in general so that if I run into a problem I'm less likely to lose a lot of progress, but I've also already run into two issues that I didn't learn about for days after (2 weeks after in one case)... storing half-hour saves for weeks is a bit much.

Is there a way to have the current configuration automatically mark a certain number of saves per 24-hour period as keep? This way I could set it to 1 and, if I have it set to hourly backups and save 24, it would give me a days worth of hourly back ups and a running single backup ongoing (maybe with it's own limit, so I could set it to something like 60 days, thereby saving 1 per day for 2 months back).

Thanks!

This isn't something that's possible with the current configuration options, but if you'd like to submit a pull request for this feature, I'm happy to review it.
