 # Backup
 
-If those [Backup](https://github.com/wekan/wekan/wiki/Backup) ways are not easily found at Cloudron, one way is to install [Redash](https://redash.io/) and then backup this way:
+[Backup Cloudron](https://github.com/wekan/wekan/wiki/Backup#Cloudron)
-
-Redash works with this kind of queries:
-```
-{
-	"collection": "accountSettings",
-	"query": {
-		"type": 1
-	},
-	"fields": {
-		"_id": 1,
-		"booleanValue": 1,
-		"createdAt": 1,
-		"modifiedAt": 1,		
-	}
-}
-```
-So:
-
-1) Create this kind of query:
-```
-{
-	"collection": "boards"
-}
-```
-
-Later when you modify query, you can remove text like boards with double-click-with-mouse and delete-key-at-keyboard (or select characters with mouse and delete-key-at-keyboard), and then click collection/table >> button to insert name of next collection/table.
-
-2) Click Save
-
-3) Click Execute. This will cache query for use with REST API.
-
-4) Click at right top [...] => Show API key
-
-It looks like this:
-
-https://redash.example.com/api/queries/1/results.json?api_key=...
-
-5) Only when saving first collection/table, Save API key to text file script like this `dl.sh` 
-```
-#!/bin/bash
-
-# Example: ./dl.sh boards
-
-export APIKEY=https://redash.example.com/api/queries/1/results.json?api_key=...
-
-curl -o $1.json $APIKEY
-```
-
-6) Run save script like:
-```
-./dl.sh boards
-```
-Note: 1) Save 2) Execute => webbrowser can give this kind of timeout,
-but downloading with API script still works:
-
-> wekan
-> Error running query: failed communicating with server. Please check your Internet connection and try again.
-
-7) Repeat steps 1-4 and 6 for every collection/table like boards,cards, etc
-
-8) Remove from downloaded .json files extra query related data, so that it is similar like [any other Wekan database backup JSON files](https://github.com/wekan/wekan/wiki/Export-from-Wekan-Sandstorm-grain-.zip-file)
-
-9) Insert data to some other Wekan install with nosqlbooster like mentioned at page [Backup](https://github.com/wekan/wekan/wiki/Backup)
