⚠ **Attention:** Make sure that the execution of the script does not collidate with the daily backups from AIO (if configured) since the target backup repository might get into an inconsistent state. (There is no check in place that checks this.)
### How to change the default location of Nextcloud's Datadir?
You can configure the Nextcloud container to use a specific directory on your host as data directory. You can do so by adding the environmental variable `NEXTCLOUD_DATADIR` to the initial startup of the mastercontainer. Allowed values for that variable are strings that start with `/mnt/`, `/media/` or `/host_mnt/`. An example for Linux and macOS is `-e NEXTCLOUD_DATADIR="/mnt/ncdata"`. On Windows it might be `-e NEXTCLOUD_DATADIR="/host_mnt/c/your/data/path"` (This Windows example would be equivalent to `C:\your\data\path` on the Windows host. So you need to translate the path that you want to use into the correct format.) Please make sure to apply the correct permissions to the chosen directory before starting Nextcloud the first time (not needed on Windows). In this example would the command for this be: `sudo chown -R 33:0 /mnt/ncdata`. ⚠ **Attention:** It is very important to change the datadir **before** Nextcloud is installed/started the first time and not to change it afterwards!

You can do so by adding the environmental variable `NEXTCLOUD_DATADIR` to the initial startup of the mastercontainer. Allowed values for that variable are strings that start with `/mnt/`, `/media/`, `/volume[0-9]/` or `/host_mnt/`.
(`/volume[0-9]/` means that all strings from `/volume1/` to `/volume9/` are allowed.)
- An example for Linux and macOS is `-e NEXTCLOUD_DATADIR="/mnt/ncdata"`.
- For Synology it may be `/volume1/docker/nextcloud/data`.
- On Windows it might be `-e NEXTCLOUD_DATADIR="/host_mnt/c/your/data/path"` (This Windows example would be equivalent to `C:\your\data\path` on the Windows host. So you need to translate the path that you want to use into the correct format.)

### How to allow the Nextcloud container to access directories on the host?
By default, the Nextcloud container is confined and cannot access directories on the host OS. You might want to change this when you are planning to use local external storage in Nextcloud to store some files outside the data directory and can do so by adding the environmental variable `NEXTCLOUD_MOUNT` to the initial startup of the mastercontainer. Allowed values for that variable are strings that are equal to or start with `/mnt/`, `/media/` or `/host_mnt/` or are equal to `/var/backups` and unequal to `/mnt/ncdata`. Two examples for Linux and macOS are: `-e NEXTCLOUD_MOUNT="/mnt/"` or `-e NEXTCLOUD_MOUNT="/media/"`. On Windows it might be `-e NEXTCLOUD_MOUNT="/host_mnt/c"` (This Windows example would be equivalent to `C:\` on the Windows host. So you need to translate the path that you want to use into the correct format.) After using this option, please make sure to apply the correct permissions to the directories that you want to use in Nextcloud (not needed on Windows). E.g. `sudo chown -R 33:0 /mnt/your-drive-mountpoint` should make it work. You can then navigate to the apps management page, activate the external storage app, navigate to `https://your-nc-domain.com/settings/admin/externalstorages` and add a local external storage directory that will be accessible inside the container at the same place that you've entered. E.g. `/mnt/your-drive-mountpoint` will be mounted to `/mnt/your-drive-mountpoint` inside the container, etc. Be aware though that these locations will not be covered by the built-in backup solution!

### Huge docker logs
When your containers run for a few days without a restart, the container logs that you can view from the AIO interface can get really huge. You can limit the loge sizes by enabling logrotate for docker container logs. Feel free to enable this by following those instructions: https://sandro-keil.de/blog/logrotate-for-docker-container/
