Comment on [Help] Backing up Nextcloud with Duplicati (Docker)

But it should not need write access to those files.

I bet it is due to different UID. Nextcloud runs with the www-data user, and UID 1000 is likely whatever user OP set up on the host machine. Make Duplicati run with the same UID as nextcloud and it will have the permission to read the files.

You are probably correct! I always forget about the UID…

IIRC nextcloud docker image uses UID 33 instead of 1000.

  I just went through dockerizing my nextcloud installation. The www-data user on my host had uid 33, but the one inside the container uses uid 82, which had me scratching my head for a minute. You can confirm the actual uid by running id www-data inside the nextcloud container.

    I have two instances on two separate servers running and all of them use uid:gid 33:33 inside the container. I use the nextcloud:26-apache docker image.

    Ah yep I bet that’s it, I’m using the alpine fpm image.
