SOLVED Backup Symlinked Data

  • When moving data to an external location like described in the docs under Moving a single app's data directory to another location the symlinked location is not part of the backup. How can I change the backup configuration to also include this data?

    The folder data is missing in the backup, whereas data_orig is there.

    @tobru You should make the /home/yellowtent/appsdata/dc3a15ad-9993-4e5c-9039-46e73d048341 a symlink instead.

    So something like:

    1. stop the containers
    2. move the data directory. in the example below, I am assuming /srv/nextcloud does not exist. If it already exists, remove it (otherwise the mv will move it as a subdirectory).
    mv /home/yellowtent/appsdata/dc3a15ad-9993-4e5c-9039-46e73d048341 /srv/nextcloud
    ln -s /srv/nextcloud /home/yellowtent/appsdata/dc3a15ad-9993-4e5c-9039-46e73d048341
    1. start the containers
