copy bootable SD to pendrive?

  • Hello!! I currently have OMV with 1 4TB disk. the operating system boots from an SD that is a bit damaged. I have bought a pendrive to replace the SD. How or what is the way to copy everything that is in the SD to the new pendrive?

    I really need to change from SD to pendrive, I am using google translator because English is not my original language, although I can understand much of it.

    Thanks for your help !! :)

  • the operating system boots from an SD that is a bit damaged.

    Not sure what you mean by “a bit damaged.” Maybe something was lost in the translation, but the best time to back up a boot drive is before it is a bit damaged. Another consideration is how much is on the boot drive.

    Maybe this post will help.

    Hello, thanks for your answer, I hope the google translator helps me !!.

    -The SD card is physically damaged and I am afraid that one day the operating system will not start.

    -SD card has only the boot system and configuration (not for saving data or files)

    -on the CPU that has a 6TB hard disk where I have very important work items and files with which I work

    -What I want is to clone what I have in SD and transfer it to a pendrive.

    -This way I will not use the SD anymore to start, I will do it from the pendrive

  • Thanks for the clarification. What machine are you using? I am not sure about any NAS that boots from a SD card that also readily lets you boot from a USB pen drive.


    Using an SD card for your boot drive is good and safe as long as you use the Flashmemory plugin on OMV-extras. A good way to back up your SD card with another SD card of same size is to use dd from the command line. Here is a link to the steps on all three platforms. There are other ways but this is what I have been doing for a long time.
