@@ -217,7 +217,7 @@ Current in-memory history caps are:
| `4 MB` to less than `8 MB` PSRAM | `480` | `192` | About `8` hours |
| `8 MB` PSRAM or more | `720` | `288` | About `12` hours |
On boards with `4 MB` PSRAM or more, stats history starts capturing from boot when `web.stats` is enabled, even if `/stats` has not been opened yet.
On boards with roughly `2 MB` PSRAM or more, stats history starts capturing from boot when `web.stats` is enabled, even if `/stats` has not been opened yet.
Archive-backed restore requires `web.stats` enabled plus a mounted SD card on boards that support the EastMesh archive path.
