Backup solution Urbackup?

  • I am looking to backup all data on an OMV server to an OMV offsite location (via public Internet).

    Can anyone comment on whether Urbackup is reliable and safe. I dont think they encrypt traffic. Right?


    many thanks

    I use Duplicati in docker for that. Alternative would be restic or a restic/rclone combo from CLI (no GUI available, I think). Depends on the protocol the offsite location supports.


    I think you would have to run UrBackup on the offsite location and the client installed on the OMV server to use it.

    You may be interested in this solution.

  • use rsync via ssh. It is easy to set up iif one of the servers is exposed to the internet port 22 (or whatever you use for ssh)

    If you got help in the forum and want to give something back to the project click here (omv) or here (scroll down) (plugins) and write up your solution for others.

  • yeah. thats what I am currently investigating.

    I am struggling a bit with the exchange of encryption keys.

    I have an OMV host on both sides (source and destination) of the backup.

    Do you know how the SSH keys need to be setup in OMV?

  • Yes,

    First on source host as root create a ssh connection from source host to target host.

    1. Create ssh key file pair using ssh-keygen
    2. copy public key to target host using ssh-copy-id
    3. try to log in to the other host with a key ssh -i path/to/key root@target and accept the key

    In OMV:

    1. Import the key
    2. set up a rsync push job on source OMV

  • OK. They key installed at destination but when trying to connect SSH still asks me for password. Shouldn't that recognise the key automatically?

  • Found a missing step. The permissions on the destination must be manually set to:


    chmod -R 755 /.../homes/[user_name]
