SCUBA's self hosted Nextcloud snap server





    scubamuc




for a self hosted [Nextcloud](https://nextcloud.com/) I turned to [Ubuntu Server](https://ubuntu.com/download/server) and [LXD](https://canonical.com/lxd) to create an [LXC container](https://documentation.ubuntu.com/lxd/en/latest/explanation/lxd_lxc/) for [Nextcloud snap](https://github.com/nextcloud-snap/nextcloud-snap). There is a great community behind Nextcloud snap and support is fantastic. The greatness of Linux together with supported hardware enables anyone to run a 24/7 Nextcloud server. 



My goal is a simple safe and reliable setup with ample resources for 5+ family users, affordable, efficient and low maintenence. My day job is software support for a leading WMS. I'm an avid scuba diver and enjoy Linux and FOSS. I'm a dad and husband thus I'm not keen on spending much of my free time doing server-maintenence.

# Procedure



## Install Nextcloud-snap in LXC container on LXD server



* Prepare [LXD server](https://documentation.ubuntu.com/lxd/en/latest/) with [Ubuntu Server](https://ubuntu.com/download/server)  and [bridged network](https://github.com/scubamuc/wiki-md/blob/scubamuc-wiki/LXD-LXC-bridged-network.md)

* Prepare [LXC container](https://documentation.ubuntu.com/lxd/en/latest/getting_started/) with [Ubuntu Server](https://ubuntu.com/download/server)

* Install [Nextcloud snap](https://github.com/nextcloud-snap/nextcloud-snap) in LXC-container

* Set [FQDN](https://github.com/scubamuc/wiki-md/blob/scubamuc-wiki/NEXTCLOUD.snap--set_FQDN.md) in `/etc/hosts` in LXC-container

* Nextcloud snap handles [Lets-Encrypt certificate](https://github.com/scubamuc/wiki-md/blob/scubamuc-wiki/NEXTCLOUD.snap--LetsEncrypt_wiki.md#enable-letsencrypt-in-nextcloud-snap) automatically with `nextcloud.enable-https lets-encrypt` 

    * *optionally* handle certificates with [reverse Proxy](https://github.com/nextcloud-snap/nextcloud-snap/wiki/Putting-the-snap-behind-a-reverse-proxy) or [NGINX-Proxy-Manager](https://github.com/nextcloud-snap/nextcloud-snap/wiki/NGINX-proxy-manager)

* [Configure Nextcloud](https://github.com/nextcloud-snap/nextcloud-snap/wiki/configure-Nextcloud-snap) and regain control over your data

# Snap backup, restore & migrate



## Backup Nextcloud snap with Snap snapshot



[snapshot documentation](https://snapcraft.io/docs/snapshots)

* snap stop nextcloud (*optional*)

* snap save nextcloud 

* snap start nextcloud (*optional, see above*)

* find snapshot in `/var/lib/snapd/snapshots` and copy/move to wherever



This works fine as weekly automatic cronjob (as root) and has the added convenience of easy snap transfer to different server when needed. Thus always 4 weeks of snap-snapshots on backup media. 



[rotating Snap snapshot script](https://github.com/scubamuc/wiki-md/blob/scubamuc-wiki/NEXTCLOUD.snap--backup_snap-snapshot.md)



## Restore Snap snapshot using Snap restore 



* when moving to new device, be sure to install Nextcloud snap first

* snap restore replaces previous installation incl. certs, DB and data

* see documentation in `man snap` and [snapcraft](https://snapcraft.io/docs/snapshots#heading--restoring)



1\. copy compressed file (\*.zip) from backup media to `/var/lib/snapd/snapshots`



2\. discover snapshot-ID using `snap saved`



3\. issue command `sudo snap restore "snapshot-ID"`

# LXC container snapshot / backup & restore



#### Backup LXC container with snapshot/image & restore in shell [scripted](https://github.com/scubamuc/scubamuc.github.io/blob/scubamuc/bash-scripts/LXC-ContainerBackup.sh) or GUI [LXDMosaic](https://github.com/turtle0x1/LxdMosaic#-lxdmosaic)



* LXC container snapshot [scripted](https://github.com/scubamuc/bash-scripts/blob/scubamuc-wiki/LXC-ContainerBackup.sh) or GUI [LXDMosaic](https://github.com/turtle0x1/LxdMosaic#-lxdmosaic)

* LXC container image from snapshot [scripted](https://github.com/scubamuc/bash-scripts/blob/scubamuc-wiki/LXC-ContainerBackup.sh) or GUI [LXDMosaic](https://github.com/turtle0x1/LxdMosaic#-lxdmosaic)
