Provide ability to limit backup folder size (deletion of most older backups, yet covering entire period )

[fad1]

Have you read the Longevity Statement?
Yes. I hope that's not too... complex :)

Is your feature request related to a problem? Please describe.
SN Backups folder grows larger and larger.

Describe the solution you'd like
Provide ability to set a size limit for it, ideally something like macOS time machine: when size limit is reached: hourly backups for past 24 hours, daily backups for past month, and weekly backups for all previous months.

Describe alternatives you've considered
Manual deletion of excess files, but one cannot easily replicate a situation where periodic yet spaced out older backups as time machine does.

Additional context
running latest SN desktop on macOS.
