I have made a backup of USER folder. around 140MB.
Do I need to backup NDATA folder? About 3GB?
I found out when I try to copy, it copies about 1GB in one hour. Is that normal? Tried different sticks, micro sd cards and even a USB 3 SSD harddisk. No difference. I have stopped backup the NDATA folder.
I understand that the installation takes about 25 minutes? That means writing data is much slower to external devices.
Please advice.
Many thanks
