Backup OMV configuration on a remote NAS for later (emergency) restore

  • Hello friends of OMV :)


    i tried looking in the forum and can not sort out my needings...


    i just want to backup my OMV settings/configurations so that in case of a system failure I would be able to do a fresh install and restore my system.


    I don't need to backup the content of attached HDDs (but it would be fine if I just can do a fresh instal, restore my system and have the same shared folders on the HDDs)


    I have a second NAS (Synology) in my Homenetwork and want to do a periodical Backup of OMV System to this Synology box.


    Would it be okay if I just shedule a rsync job and copy the whole system HDD to my syno box?


    Or can this be easily be done with the backup plugin?


    Any help would be appreciated :)


    Thank u


    /edit: and what would be the best way to restore system after a fresh install?? :/

    Not possible. You have to make a backup of the complete OS drive.


    Easiest way is to make a clone or an image of the OS drive, e.g. with clonezilla.

    There is also the backup plugin which uses various methods. If you want to use it, make sure you test the restore process. There are some threads how to do it.

  • If your OS is on a SD card or USB stick this link has a good backup method.

    Simple and sure backup and restore: In a Scheduled Job: rsync -av --delete /srv/dev-disk-by-label-SOURCE/ /srv/dev-disk-by-label-DESTINATION/ (HT: Getting Started with OMV5)
    Server Software: OMV 5 (current) - My Main Server: Thinkserver TS140, Nextcloud, Plex, Airsonic, Navidrome, Ubooquity, Digikam, & Heimdall - My Backup Machine: NanoPi M4 (v.1), Pi-Hole - Odroid XU4 (Using DietPi) - Testing/Playing: hc2, xu4, Pi 3B+, Odroid H2.
