Using “Direct restore from backup files” will create a partial temporary database tailored to that restore.
I hope that means in the past, and you survived the heavy compacting. If recent change, beware of that.
You are perhaps saved from compacting (for now) because you keep all versions, but you want change:
Remove remote versions after switching to smart retention
and I don’t want your compact to be very long like this case:
How long to compact, and why no logging? Is it stuck?
Yes, but (making up stats) if 10% of time is fetching, and 90% is processing blocks, fetch matters little.
You would have to look at your own logs to get some sense of timing, but it might slow as DB gets big.
