Proposal: allow a lower value for snapshots.automatic.retention (backup)

Error: cannot perform the following tasks: - Run configure hook of "core" snap (run hook "configure": snapshots.automatic.retention must be a value greater than 24 hours, or "no" to disable)

proposal: allow a lower value for snapshots.automatic.retention (backup) a minimal of 2 hours would be perfect. with option to replace previous backup or add a new one.
