Description

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.
