B6 #14 — app removed keeping its data, installed again with „use my kept data" (Paperless-ngx)
Run 2026-10-20 20:10–20:14 UTC on Tester4 (VM 9320, controller 0.336.0). Method: endpoint-level — the same
requests the dashboard sends (/api/stacks/paperless-ngx/stop, /remove, /deploy), the „Megőrzött adatok"
page read as HTML, the documents counted and downloaded through Paperless's own API by the user irisz.
| step | result |
|---|---|
| before | 47 documents, 8 failed imports |
| Remove, keep data | 200 in 39 s; three Docker volumes removed; drive folders media (2.4 MB) and export kept; verified: true |
| „Megőrzött adatok" page | lists „Paperless-ngx 2026. 10. 20. 14:49 · 2,2 MB", „Visszatölthető innen: saját mentés, 2026. 10. 20. 21:57", buttons Betöltés / Megnézem / Törlés; says „Erről nem készül mentés." |
| install, no choice | 409 kept_data_choice: „Ennek az alkalmazásnak megvannak a régi adatai" + the two choices; the „use" text names the copy and warns „Ami ezután változott, hiányozhat." Nothing installed |
| install, „use" | 202, load started; app running after 30 s; Paperless answered after ~2 min |
| after | 47 documents, the same 8 failed imports; 47 of 47 originals download |
Verdict: PASS. No data lost. The page tells the household which copy it uses and that later changes can be missing. Times on the page are local (CEST); the copy is the 19:57 UTC unit from B8.
Not tested here: a document added AFTER the newest copy (its file would stay on the drive with no database row) — the page warns about it in words; not reproduced.
