That's the value for ext4. I think I recall reading that while I was flailing over this, yes. ext4 is what I use for daily-driver purposes these days; from the little I've looked into the matter, everything else seems to be either too complicated, or too non-robust, to be worth risking my live data on. > XFS has a much larger limit I believe.

So it might make sense to use one of those as the underpinning for whatever external system I wind up setting up for tiered backup, then. Though experimentation to determine the limits would be warranted. That's not immediately actionable, but it's good to have in the background as planning etc. takes place. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
