Automatic_Back-Ups/README.md

This script checks if changes happened to a given list of files, and if so, it'll store them into a next version as back up.

## Setup
Install git.  
Create a folder that should act as your automatic archive.  
Open that folder with your terminal and execute ```git init```  
Create a file in the folder called ".gitignore" and put the following in it:  
```
backup_routine.sh
backup_filelist.txt
log.txt
```
Create the files "backup_routine.sh" and "backup_filelist.txt" in this folder.  
Copy the code from "backup_routine.sh" in this repository into yours.  
Put the complete filepaths to the files you want to automatically be versioned into "backup_filelist.txt".  
Now use ```git add *``` and ```git commit -m "initial commit"```   
You're done setting up your automatic archive.  

---
## Automation  
Make it so that "sh backup_routine.sh" gets called automatically. I recommend setting up a cron job, for example by executing ```EDITOR=nano crontab -e``` and writing the following into crontab:
```
0,15,30,45 * * * * cd ~/Automatic\ Git\ Versioned\ Backups && sh backup_routine.sh
```
This will run the script every 15 minutes.

---
## Restoration
Use
```
git log -- filename.ext
```
to view all the past versions.  
Copy the commit-id of the version you wish to restore.  
To recreate a past version, use  
```
git show commit-id:filename.ext > path/to/restoration/filename.restored.ext
```
For example: ```git show 8f1dc7362dd5f6781ccf9ccc5a9cfdccb57ed709:ToDo.xlsx >> ToDo.restored.xlsx```
