Has anybody tried a solution to backup SD cards that doesn’t require a computer? Ideally something with a SD card reader that takes an NVMe M.2 SSD.
depending on what you mean by “requiring a computer” there is GitHub - outdoorbits/little-backup-box: This software turns a single-board computer into a versatile, pocket-sized backup solution. Especially for digital photography, this is the solution for backing up images and media files on mass storage devices when traveling or at events. Media content can be viewed and rated for the subsequent process.

The good news is that both SD card and SSD are recognized via the hub. However, the typical android file managers seem to get confused once more than 1 USB device is attached. The OS recognizes 2 different devices, but the file managers can only access the one added last. So, that seems not to be the solution, unfortunately …
I know about this, but I haven’t tried it:
