Migrating Duplicati from OMV4 to OMV5

  • Hello there,

    first things first: great forum! Thank you very much!

    Concerning my question:

    I am preparing for a migration from OMV4 to OMV5 in the near future. Since I use OMV for plain file serving purposes only, my greatest fear would be to lose my Duplicati backups.

    My understanding is, that Duplicati will not be provided as a plugin anymore. So I'll have to learn to use Docker (not really my question here).

    Is there a migration guide on how to correctly shutdown, transfer und reinstate Duplicati in order to not lose my backup history and, ideally, backup index?

    Please enlighten me, if you can. :)

    Best from Mainz,


  • This is a great question - and I'm sorry there are no replies. I too am migrating from OMV4 to OMV5 and have over a year of Duplicati backups to B2.

    To provide more detail - I have an OMV4 server and an OMV5 server. My intention is to take the data drives out of box 1 and insert them into box 2 because in both cases the OS is running on an isolated SSD.

    Is there a way to migrate the DB that is foundational to Duplicati from one container to another?
