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

> 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.
