Hello,
I started using OMV recently and came across the problem with OMV system backup. I made system disk backup using backup plugin. In the forum I found this instruction to restore a backup. After restoring the backup, I tried to reboot from new USB, but the OMV will not boot at all. I used new freshly formatted USB.
After executing dd command my new USB looks like this. Here is the output of fdisk:

My new USB is 59 Gib sdb and my current USB is 29 GiB USB sdc.
