Hi, is the goal to have an image of the currently mounted SD card on a HDD?
If yes https://www.raspberrypi.org/fo…47568&hilit=backup+to+img has a working solution
Have a look at usbimager
mopedfahrer I just learned that the plugin openmediavault-backup and selecting "dd" as method might be the easisest method to achieve your Goal. Have a look at https://github.com/openmediava…75#issuecomment-778485817 and provide feedback please.
Backup is easy with that plugin. Restore is another story. mopedfahrer if you want to use it, make sure to test the restore process as well.
IMHO creating a clone with usbimager or clonezilla or win32imager is much easier, not so comfortable, though.

macom, would you mind to add the necessary steps for "restore" or at least the concerns to the GH issue? This would perhaps allow to improve the plugin but at least to update the doc with complete information
Here is the super short version for dd and fsarchiver
RE: How to restore from an omv-backup?
here a long version for fsarchiver
How to restore OMV 4.X from backup-plugin to system SSD
Challenge is the large number of variables resulting in many scenarios to explain is to users with a large variance in Linux knowledge..
I also thought that Win32DiskImager is an easy way, but Windows doesn't recognize my SD card with OMV (debian installed via Petitboot), so I can't select anything to backup. With all my Raspberries with Libreelec or Batocera it works without problems. There it was also enough that only one partition is selected, the image is then always made from the entire card. I will try whether I make a small fat partition on my Debian card, so I can back up my card so.
How about testing usbimager?

So I have tested USB imager. Is actually good, especially the size of the backup - and also the speed. But the restore worked for me only on identically large cards. Win32diskimager can also restore on larger cards, which I do quite often - to then increase the partition in gparted.
Here is what I do to backup my running Pi SD-Card
#!/bin/bash
# VARIABLEN - HIER EDITIEREN
BACKUP_PFAD="/backup"
BACKUP_ANZAHL="1"
BACKUP_NAME="RaspberryPiBackup"
# ENDE VARIABLEN
# Backup mit Hilfe von dd erstellen und im angegebenen Pfad speichern
dd if=/dev/mmcblk0 of=${BACKUP_PFAD}/${BACKUP_NAME}-$(date +%Y%m%d-%H%M%S).img bs=1MB
# Alte Sicherungen die nach X neuen Sicherungen entfernen
pushd ${BACKUP_PFAD}; ls -tr ${BACKUP_PFAD}/${BACKUP_NAME}* | head -n -${BACKUP_ANZAHL} | xargs rm; popdHTH
This would perhaps allow to improve the plugin but at least to update the doc with complete information
How is the update of the documentation going?
