Restore existing Borg backup to a new installation

mstrauss22 · December 21, 2024, 7:33pm

I searched the community on this but only found this 1 link.

In general makes sense but I don’t understand when it says “Start a new AIO installation and enter the password and location of the archive on the server instead of the domain.”

Where exactly do you enter the password and location of the archive when you START a new installation. I am reinstalling Nextcloud-AIO 10 and would like to restore my backsups of my encrypted data.

I tried ChatGPT and it was no help.

Basically, I had a nextcloud-AIO 10 installation utilizing built in borg backups. The data in ncdata was encrypted.

I have the ncdata folder intacted and I have the borg backups intacked. I installed a fresh version of Nextcloud-AIO 10 and now I am trying to connect the new install to my borg backups so that I can restore from the bakcup and get my NC data imported into this new installation.
The link above is the only reference I could find on how to do this. I couldn’t find anything that addressed this in the NC documentation.
I would think the process would be easy and well documented since the backups are an essential part of recovery.

Anyone have any ideas?

Much appreciated

Mike

Hi, see GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance.

When I follow the installation instructions, I put
sudo docker run
–init
–sig-proxy=false
–name nextcloud-aio-mastercontainer
–restart always
–publish 80:80
–publish 8080:8080
–publish 8443:8443
–volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config
–volume /var/run/docker.sock:/var/run/docker.sock:ro
–env NEXTCLOUD_DATADIR=“/mnt/ncdata/”
–env NEXTCLOUD_UPLOAD_LIMIT=16G
–env NEXTCLOUD_MEMORY_LIMIT=512M
nextcloud/all-in-one:latest

When it was done, the containers started automatically. The instructions say not to start the containers yet.

So far I have not seen the Select the “Restore former AIO instance from backup” option

Sorry, Tired. Let me rephrase this.

When I follow the installation instructions, I put
sudo docker run
–init
–sig-proxy=false
–name nextcloud-aio-mastercontainer
–restart always
–publish 80:80
–publish 8080:8080
–publish 8443:8443
–volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config
–volume /var/run/docker.sock:/var/run/docker.sock:ro
–env NEXTCLOUD_DATADIR=“/mnt/ncdata/”
–env NEXTCLOUD_UPLOAD_LIMIT=16G
–env NEXTCLOUD_MEMORY_LIMIT=512M
nextcloud/all-in-one:latest

Then I log into the AIO interface, enter my domain name
enter my borg backup location (At this point there is no place for a borg passphrase)
Enter my timezone and choose the optional containers to install.
Then I click Install Containers.

When it was done, the containers started automatically. The instructions say not to start the containers yet.

So far I have not seen the Select the “Restore former AIO instance from backup” option

This is what is wrong. Instead of entering your domain, you scroll further down and have the option to restore the former instance from backup.

mstrauss22 · December 22, 2024, 5:48pm

Uggh,
I can’t believe how stupid I am.
Wait! Yes I can - lol
This worked great.
At first I was excited, but now I’m depressed because even though the resote worked, this won’t work for me.

The reason I reinstalled NC is because I didn’t install the proxy container originally and I wanted to get it installed to start learning how to work with the API.

How can I install the proxy container AND restore from backup?

szaimen · December 22, 2024, 7:13pm

This depends on how you installed the proxy container before…

mstrauss22 · December 22, 2024, 9:38pm

I never did install the proxy container before. This would be the first time.
Considering how you restore from backup on a new install, this makes me think that when you have to reinstall from scratch and add a container like I do, the restore isn’t possible.
If I am right, then is there a way to add the proxy container in my current installation? I assume if there is, then I can still have access to my backups.

The way I installed:
Installed on ubuntu 22.04
Downloaded and installed the Docker image from nextcloud.com
Followed these instructions for installation: GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance.

I used the convenience script in step 3

szaimen · December 22, 2024, 10:08pm

Sorry, I am confused. So you say you did not have a RP container on the old instance that you restore from backup but you want to have one now?

This should be possible by following https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md - so some things need to be adjusted. However a restore of the former backup should still be possible. You still follow GitHub - nextcloud/all-in-one: 📦 The official Nextcloud installation method. Provides easy deployment and maintenance with most features included in this one Nextcloud instance. in parallel.

I read through https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md and I have no clue what to do; it looks very complicated.
I tried to ID the part that installs the proxy but could not.

mstrauss22 · December 23, 2024, 9:46pm

I reread the link to try to understand the process. IT talks about configuring the proxy before installing NC. But how can I do that if the proxy isn’t even installed yet?
Also, The restore seems to not only restore files but the entire NC cnfiguration which means even if I get the proxy installed, wouldnt a restore wipe it out since it is not part of the backup?

# Reverse Proxy Documentation

> [!NOTE]  
> The maintainers of AIO noticed that this documentation could be improved to make it easier to follow. All contributions that improve this are very welcome!

A [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy) is a software service that acts as a gateway between services and a client. It is commonly used to allow a client connected to the Internet to access a website located in the [private subnet](https://en.wikipedia.org/wiki/Private_network) of that web server.

**Please note:** Publishing the AIO interface with a valid certificate to the public internet is **not** the goal of this documentation! If you need a valid certificate for the AIO interface, see [point 5](#5-optional-get-a-valid-certificate-for-the-aio-interface).

In order to run Nextcloud behind a web server or reverse proxy (like Apache, Nginx, Caddy, Cloudflare Tunnel and else), you need to:
1. specify the port that AIO's integrated Apache container shall use
2. add a specific config to your web server or reverse proxy
3. modify the startup command a bit.
All examples below will use port `11000` as `APACHE_PORT`. This port will be exposed in the private network to receive unencrypted HTTP traffic from the reverse proxy.
> [!IMPORTANT] 
> If you need HTTPS between Nextcloud and the reverse proxy because it is running on a different server in the same network, simply add another reverse proxy to the chain that runs on the same server like AIO and takes care of HTTPS proxying (most likely via self-signed certificates). Another option would be to create a VPN between the server that runs AIO and the server that runs the reverse proxy which takes care of encrypting the connection.

**Attention:** The process to run Nextcloud behind a reverse proxy consists of at least steps 1, 2 and 4:
1. **Configure the reverse proxy! See [point 1](#1-configure-the-reverse-proxy)**
1. **Use this startup command! See [point 2](#2-use-this-startup-command)**

Which part of this website actually gets the proxy installed?

szaimen · December 23, 2024, 10:04pm

Sorry, I have the feeling you are very unfamilar with Reverse Proxies so I am not sure if I am the best one to help you with this.

May I ask why do you want to run AIO behind a RP since you formerly apparently didnt? Running it without one is much easier as you probably already found out…

mstrauss22 · December 23, 2024, 10:39pm

When setting up NC the first time over 2 years ago, I chose not to install the proxy container because I dont run NC behind a proxy.

Now that I want to learn API and how to use it with NC, I found out that to access the API (and make entries to the calendar) I have to have the proxy container installed. That’s the only reason I want to install the proxy container in my nextcloud.

mstrauss22 · December 27, 2024, 11:54pm

Looks like this is a situation noe one has thought of. Bummer.
Might be a good idea to make a way to restore data only from a bakup after a new install; for cases like this.

I have exported my calendars and manually made copies of all my notes, recipes, etc… and reinstalled NC to include the proxy container, then put all my info back in. Seemed like the fastest approach at this time.

Thanks for trying, I appreciate it

szaimen · December 28, 2024, 11:45pm

No, actually this situation is indeed considered in the restore process: the environmental variables that you set for the mastercontainer are going to overwrite the settings that you would restore. So your use case is indeed possible.
