> 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.
