[18.04.2021] Privacy Regained - Self-hosted local git with automatic backups on Linux
If you consider hosting your own local git instance, because i.e. you don't want to store code outside your machine, but you want to sleep well and not worry about data loss, then you might find this article useful.
I will guide you through few steps to set it up in minutes. Where you see placeholder like YOUR_USERNAME, put your own data in accordance with context.
OS: Linux
Tools: rsync, git, anacron, nano (or any text editor)
Devices: computer, USB drive or external HDD/SSD drive
0. Mount USB drive - your drive will be mounted under path like /media/user/writable/. In order to check list of mounted drives, run ls /media/YOUR_USERNAME/
1. Create copying script - let's assume you will write NodeJS code inside your git repository. In order to prevent copying unnecessary dependencies, we will exclude node_modules from copying for every subfolder. To create a copying script, run nano and paste:
rsync -avr --exclude='*/node_modules' /home/YOUR_USERNAME/Documents/self-hosted-git/ /media/YOUR_USERNAME/writable/self-hosted-git
We are using rsync for copying files from drive to USB drive.
2. Make script executable - to give executable permission to script, run chmod +x
3. Create local git repository - in our example, repository will be placed under path /home/YOUR_USERNAME/Documents/self-hosted-git/, so just create a folder called self-hosted-git inside Documents folder. To do it, invoke mkdir self-hosted-git. Then, navigate inside a folder and initialize local repository with git init.
4. Create backup script. In order to create it, you need to create a folder inside /etc/. Invoke sudo mkdir /etc/self-hosted-git-backup.daily. Navigate inside this folder and create a script using sudo nano self-hosted-git-backup. Inside a file, paste:
It will invoke our copying script.
5. Schedule backups. In this example, we will be fine with daily backups. Open backups configuration file using sudo nano /etc/anacrontab. Navigate to bottom of the file and paste:
1 0 self-hosted-git-backup.daily run-parts --report /etc/self-hosted-git-backup.daily
(Optional) 6. Verify correctness of the backup process. You can force invoke backup in order to check if all is set up correctly. Simply run sudo anacron -f -d self-hosted-git-backup.daily
And you did it - you created automatic backups for your private git repository. You can modify this process to be more customized for your needs.
Take care
