      do you have to do the dd to restore grub on the new disk that you are restoring?
      If it is a new disk, it wouldn't have grub on it. So, yes, you would have to restore grub. BUT you are talking about a helios which does not use grub.

      My thought would be

      1. Write helios 4 armbian to sdcard
      2. Restore fsarchiver to new disk partition

      or

      1. Partition new sd card to what you have before
      2. dd grubparts
      3. fsarchiver to new sdcard partition
      The first option would work the best.

      Hallo OMV,
      wo ist der unterschied zwischen dd und fsarchiver Methode?
      Ich verstehe den unterschied nicht ganz.
      dd - use dd to clone the entire drive to a compressed image file.
      fsarchiver - use fsarchiver to clone all partitions to an archive file

      Wie wird genau die rsync Methode verwendet / eingesetzt?

      Was ist besser, was wird empfohlen?

      Vielen Dank!

      dd does not clone the entire drive. It clones the entire OS partition (and potentially a boot partition) including sectors that don't have information on them. This takes longer. It also can't restore to a smaller partition than it cloned from.
      fsarchiver clones the same thing as dd does but it only clones the files saving a lot of time and allowing (to some extent) to restore to a small partition.
      rsync just rsyncs the OS files to another directory on a data drive.

      Which one is the best? No one can tell you that. What ever works for you. rsync only allows one backup. The other two allow multiple backups. Personally I use fsarchiver.

      Sehr Hilfreich, ich habe bisher dd benutzt, ich werde es demnächst mit fsarchiver ausprobieren.

      Gibt es eventuell eine Lösung das man Komplett das ganze img Sichern kann und bei Ausfall des Systems einfach nur das "gesicherte / Backup image" wiederherstellen braucht. (Natürlich außer "Win32DiskImager" etc. wo man z.B. dei sd/emmc Karte ausbauen muss?)

      Vielen Dank für die Erklärung der Funktionen.

      It is perhaps a solution that you can completely backup the whole and in the case of failure of the system just restore the "backed up / backup image" needs.
      The backup plugin won't backup a data partition if you are using one on the OS drive but it does backup enough to do a restore - forum.openmediavault.org/index…kup-plugin-to-system-SSD/
