Our guidance is to put the replicated log on a separate device. Does that not

> Currently, backup files are written asynchronously and overlay with the peak
> of GC cleaning up after persisting snapshot in native log. We should
> generally avoid overlaying resource-heavy activities when possible to avoid
> troubleshooting complicated performance related issues.
> Consider delaying backup file write (e.g. for 1 minute) to clearly separate
> its impact from the snapshot GC.
