BACKUPMON BACKUPMON v1.9.0 -Sep 6, 2025- Backup/Restore your Router: JFFS + NVRAM + External USB Drive! CIFS/SMB/NFS! (Available in AMTM!)

[ExtremeFiretop]

This would eliminate need to load nvram backup onto router.

If this is in reference to my post with RMerlin, I like the idea!
Just for reference though; I wasn't going to load the backup into my router anyways to get the value.
I use an app called "WRT Settings" to read and/or modify the nvram values manually.

Seems it's out of support but has continued to work for me: https://medo64.com/wrtsettings/

Yes, that is exactly where my request originated. Also, it would allow one to easily perform diffs over time of nvram values.

FYI - just to be safe, I "rolled my own" version of this a while back in Excel. Not sure if (or whether) I can share macro-enabled Excel file, but here are the pieces.

The main sheet is shown here (formulas shown):

And the macro that runs when the button is pushed is here:

Sub Button1_Click()
        Dim byteArr() As Byte
        Dim fileInt As Integer: fileInt = FreeFile
        Dim datasize As Long
        Filename = Range("D1").Value
        Open Filename For Binary Access Read As #fileInt
        filesize = LOF(fileInt)
        ReDim byteArr(1 To LOF(fileInt))
        Get #fileInt, , byteArr
        Close #fileInt
        Range("A:A").ClearContents
        For i = 1 To 8
            Cells(3 + i, 1).Value = byteArr(i)
        Next i

        Range("D3") = filesize
        Range("D4") = Chr$(byteArr(1)) + Chr$(byteArr(2)) + Chr$(byteArr(3)) + Chr$(byteArr(4))
        datasize = byteArr(7)
        datasize = datasize * 256 + byteArr(6)
        datasize = datasize * 256 + byteArr(5)
        Range("D10") = datasize
        randnum = byteArr(8)
        Range("D11") = randnum
        rownum = 13
        strdata = ""

        For i = 9 To 9 + datasize - 1
            If byteArr(i) < 253 Then
                 strdata = strdata + ChrXXX(255 + randnum - byteArr(i)) <- remove "XXX", forum bug
            Else
                Cells(rownum, 1) = strdata
                rownum = rownum + 1
                strdata = ""
            End If
        Next i
                
    End Sub

Not sure how universal this is, but it worked for all my cfg files.
