Hello.
My offline backup method for OMV is done by shutting down the RPi, removing the SD card, doing a full DD (all partitions) to an image file (in a Linux Mint installation).
When trying to restore, by doing DD again from the image file to a new SD card, I can never get the system to boot properly, it complains of an issue in one of the partitions.
If I do the same exact DD command but directly from an SD card to a new SD card (same size, brand, etc), I can properly boot from the new SD card.
Any reason why the dd to image and image to new SD card would not work?
Thanks in advance for any help.
