 **Evening follow-up (controller 0.276.0).**
 - **Fixed: moving an app to another drive made the box forget which version the app must run.** The app then took the newest version at its next start, and skipped the tested steps. Found by reading the code, not on a box. Tested in code only: no test box has two drives.
 - **Fixed: after a restore, the box forgot the old database copy, so it stayed on disk forever.** A restore now keeps that note, and also keeps whether you had the app switched on.
+- **Seen in the night: the scratch box deleted paperless's old database copy by itself**, after a backup made by the new database version. This is correct.
+- **Found in the night: the HP box's full-guest restore test can never run.** It now picks the right backup, but the disk has 21 GiB free and the test needs 31 GiB. It refuses safely every 6 hours. Filed, with three options; nothing decided.
 - **Not built: "Use my kept data" from the off-site copy.** It would be a new way to put data back, and no test box has an off-site copy to prove it on.
 
 **What broke, or is not done.**

 - **"Use my kept data" still cannot load from the off-site copy.** Filed.
 - **The file-browser group fix is tested in code only.** No nextcloud kept folder existed on the scratch box.
 - **A backup stores the name of each app version, not the app itself.** If a maker deletes an old version, a restore of it cannot start. Today all 42 versions the catalog names still exist. Filed with options; nothing decided.
-- **Not watched yet:** the HP box converts paperless tonight; the scratch box releases its old paperless copy after tonight's backup.

 **Decision for you — D4: when the only backup holds data of an older app version, what does a restore bring back?**
 - **A — the older version with its own data; then the normal update climbs, one tested step at a time (I recommend this, and it is built).** Cost: after the restore the app runs an older version for a night or until someone presses Update. The page says so.
