Persistence variables

[Waterbrain]

I have a stream that stores and retrieves global variables in the file system:

In SS prep data, te code is:

var saveList = global.get("saveList");
var mylist = saveList.split(";");
var outputs = [];
var i = 0, texto = "", color = "";
for (i=0; i<mylist.length; i++) {
    outputs.push({ key : mylist[i], type: typeof global.get(mylist[i]), value: (typeof global.get(mylist[i]) === "undefined") ? 0 : global.get(mylist[i])});
}

msg.payload = outputs;
msg.filename = "globalStatus.json";
return msg;

Which are saved via savefileout node.

When I need them via "Restore vi" node:

var output = [];
var msgr = { payload : "Restore vi"};
//node.warn("restaura desde json" + msg.payload);
//return msg;
for (var i=0; i<msg.payload.length; i++) {
    //node.warn("restaura " + msg.payload[i].key +" con el valor: " + msg.payload[i].value);
    switch (msg.payload[i].type) {
        case 'undefined': 
            // the global variable probably had no value, nothing needs to be restored
            output.push(msg.payload[i].key + " is undefined.");
            break;
        case 'number':
            if (msg.payload[i].value==="NaN") {
                // there is no valid value to be restored, skip this variable
                output.push(msg.payload[i].key + " is NaN.");
            } else {
                if (msg.payload[i].value.toString().indexOf(".")>-1) {
                    // the value appears to be a float
                    global.set(msg.payload[i].key,parseFloat(msg.payload[i].value));
                    output.push(msg.payload[i].key + " is restored to " + msg.payload[i].value);
                } else {
                    global.set(msg.payload[i].key,parseInt(msg.payload[i].value));
                    output.push(msg.payload[i].key + " is restored to " + msg.payload[i].value);
                }
            }
            break;
        case 'string':
            global.set(msg.payload[i].key,msg.payload[i].value);
            output.push(msg.payload[i].key + " is restored to " + msg.payload[i].value);
            break;
        case 'boolean':
            global.set(msg.payload[i].key,msg.payload[i].value==="true");
            output.push(msg.payload[i].key + " is restored to " + msg.payload[i].value);
            break;
        case 'object':
            global.set(msg.payload[i].key,msg.payload[i].value);
            output.push(msg.payload[i].key + " is restored to " + msg.payload[i].value);
            break;
    }
}
msgr.restored = output;
return msgr;

The problem is that as Node-Red works embedded in HomaAssistant and when you restart the file where the variables are saved, oh it has disappeared.

Is there any way to achieve a persistence of these files?

I imagine that since it is dockerized, when the image is booted, its virtual space disappears.

Outside of HomeAssitant this works perfectly and in the sawdust.js file I don't see how to do it.
