If your server has port 80 and 8443 open and you point a domain to your server, you can get a valid certificate automatially by opening the Nextcloud AIO Interface via:<br>
-`8080/TCP`: Mastercontainer Interface with self-signed certificate (works always, also if only access via IP-address is possible, e.g. `https://internal.ip.address:8080/`)
-`80/TCP`: redirects to Nextcloud (is used for getting the certificate via ACME http-challenge for the Mastercontainer)
-`8443/TCP`: Mastercontainer Interface with valid certificate (only works if port 80 and 8443 are open and you point a domain to your server. It generates a valid certificate then automatically and access via e.g. `https://public.domain.com:8443/` is possible.)
-`443/TCP`: will be used by the Nextcloud container later on and needs to be open
-`3478/TCP` and `3478/UPD`: will be used by the Turnserver inside the Talk container and needs to be open
### How to resolve `Security & setup warnings displays the "missing default phone region" after initial install`?
Simply run the following command: `sudo docker exec -it nextcloud-aio-nextcloud php occ config:system:set default_phone_region --value="yourvalue"`. Of course you need to modify `yourvalue` based on your location. Examples are `DE`, `EN` and `GB`.

Nextcloud AIO provides a local backup solution based on BorgBackup. These backups act as a local restore point in case the installation gets corrupted.
It is recommended to create a backup before any container update. By doing this, you will be safe regarding any possible complication during updates because you will be able to restore the whole instance with basically one click.
If you connect an external drive to your host, and choose the backup directory to be on that drive, you are also kind of save against drive failures of the drive where the docker volumes are stored on.
Backups can be created and restored in the AIO interface using the buttons `Create Backup` and `Restore last backup`. Additionally, a backup check is provided that checks the integrity of your backups but it shouldn't be needed in most situations.
The backups itself get encrypted with an encryption key that gets shown to you in the AIO interface. Please save that at a safe place as you will not be able to restore from backup without this key.
