 # Completed Steps
 
+- 2026-10-08: Kept the progress line of a snapshot with more than one
+  path within 100%
+  ([issue #271](https://git.eeqj.de/sneak/vaultik/issues/271)). The
+  bytes and files processed counted every path, but the totals they
+  were divided by held only the current path's, so a second path
+  smaller than the first showed more than 100% and an ETA of `unknown`.
+  The totals now add up over the paths scanned so far, and the rate is
+  measured from when the first path's processing started.

 - 2026-10-08: Made a second `snapshot create` of one name succeed when
   it starts in the same second as the first
