I'm running OMV5 on a Raspberry Pi4. The easiest way to make backups is to clone the sd card with win32 disk imager and to restore with etcher.
However, my system is physically stored away somewhere... i need to climb a latter to physically access the pi.
I therefore was looking into the backup plugin. The plugin's gui reads that "dd - use dd to clone the entire drive to a compressed image file". I therefore expected one single img file, however, the backup created several files (gz, blkid, fdisk, grub, grubparts, packages). since dd is capable of writing sigle img files, it would be very handy if there would be a parameter for this. This would be very handy to single-board computer users like myself, because one needs just etcher or something similar to restore the image to a SD card.
Is this doable?
