I don’t understand where the load comes from, besides “load” is not a great indicator of what’s going on. With which version of restic was that exactly? Which type of “load” are we talking about (CPU, IO, memory)? If it’s CPU load, how about using nice? If it’s IO load, why not use ionice?
All are honest questions, I’m trying to understand what happened here and how we can possibly improve the situation within restic (if it cannot be addressed with standard tools)…
