I tested it with a RASPI 4B: (64GB)
OMV Backup full dd:
on same card: works
on different card: always an error when you try to flash it.
manual backup with dd count:
on same card: works
on different card: works
Like mentioned before, you need enough sectors. When your backuped card has more of it, you have no chance without count even if your partion is already shrinked.
Alles anzeigenFor some reasons I still do not fully understand, my OMV set-up neither could be reached over LAN nor was booting properly.
I therefore ...
- connected the SDD with the backups to a laptop running Ubuntu,
- downloaded the newest version of etcher (since I was on an Ubuntu machine, I used Linux 64Bit appimage),
- flashed the latest full backup (ddfull) to my spare sd card,
- removed the power cable from my pi,
- swapped the sd card with the one with the newly flashed backup,
- powered up the pi and volia: everything is back to normal!!!
I'm not sure why etcher now worked flawlessly compared to my dry-run in April 2020. Last try, I was using etcher on a Windows PC and now on Ubuntu. Not sure whether that was the reason. Anyways, usbimager is available on various systems (Windows, Linux, etc.).
Many many thanks for the backup plugin: it definitely saved my say.

it is an old thread but i think i know what is the culprit here. If you backup your sd card/SSD, you have to use after a failure another card/ssd, which does not have as many sectors as last card/storage even if they have the same amount of space. To workaround this behaviour, i normally shrink the partition (for example 100 MiB) before to be sure that it will fit on the card with the same nominal space. I will test if you can use afterwards the dd full command in OMV.
Normally I use the dd command with the count method, which should copy a little more sectors than the shrinked partition, which worked flawlessly. I keep you updated
Have you solved your problem already? I encountered the same problem with OMV 6. WOL active at OMV GUI and Ethernet interface stays at g, so everything should be fine but something is still disabling the network device before shutdown. (BIOS is configured for WOL)
Hello,
i have a question due to plex. At the moment i have OMV 3 and everything works perfect. I am using the union file system and created a pool.
At the moment i have the library of plex at a specific hdd (this HDD is also at the pool), not a pool path.
But when on this HDD is not enough space anymore, i have to transfer the library to the pool path. When i change the path in the OMV GUI, does it automatically move the whole media library or do i have to copy it manually?
How should i proceed in such a situation?
Thank you for your help!
