Where to install Docker & OS (omv) backup ?

  • Hello,


    I ma new to this forum and to OMV.
    I have a fresh OMV 4.x installed in a 64Gb USB flash Drive ( flashRAM plugin activated ), 8Gb RAM, 2x2TB WD Red.


    My target is:


    HD1 (2Tb)alpha
    HD2 (2Tb)beta ( mirror of HD1 by rsynch scheduled job )


    Run NextCloud in order to manage HD1 content ( using external storage plugin )


    Since there is no any plugin for NextCloud I have installed it under Docker.


    • Is it correct to install Docker and its content under the OS USB flash drive ? It seems to me that is slowing down everythings. i'd like to minimaze the access to the USB key.
    • Can I install docker and its content in my HD1 drive ?
    • If my OS disk will fail I‘d like to manage a OMV backup that permits me to change my USB flesh drive and get everythings up and running smoothly and quickly. How should I achieve this goal ?


    Do I have to plan to replace my USB flash drive with a low cost SSD USB HD ?


    Thank you

    You install Docker on your USB but you can point your config files to HD1...for instance in @TechnoDadLife videos he references a folder called AppData this is a shared folder he has created on one of his drives, he points the Docker container config and settings to that folder, so for instance Nextcloud would appear under /sharedfolders/AppData/Nextcloud. He also sets AppData as an SMB share so that a folder called Nextcloud can be created from a windows or linux machine.


    So to answer your second question Docker itself remains on the USB, the config files and relevant set up can be stored a on HD...sort of outside>>>inside.


    There is a plugin specifically to back up your working O/S

    Raid is not a backup! Would you go skydiving without a parachute?
