I wrote the following python script because my Raspberry Pi failed once and I couldn't get to my apps and files anymore. This script creates a backup of relevant folders and uploads it automatically to your Dropbox
Important: You need to install dropbox on your raspberry pi (cf. https://pimylifeup.com/raspberry-pi-dropbox/)
Copy this skript (20_12_31_Backup.py) on your raspberry pi and chance the folders you want to backup into your dropbox cloud.
#!/usr/bin/python
import re
import time
import datetime
import shutil
import glob
import os
import subprocess
#TIME
UnixTime = int(time.time())
print (UnixTime)
currentdate = datetime.datetime.fromtimestamp(UnixTime).strftime('%Y-%m-%d') # creates a string with current date
print(currentdate)
output_filename = "PiBackup_" + currentdate
dir_name = "/home/pi/Dokumente/Programme" # insert your folder which you want to upload into your dropbox cloud
shutil.make_archive(output_filename, 'zip', dir_name)
time.sleep(10)
#Dropbox Upload
targetPattern = r"/home/pi/*.zip" #search for the current backupfile
a = glob.glob(targetPattern)[0] #search for the current backupfile
os.system("/home/pi/Dropbox-Uploader/dropbox_uploader.sh upload " + a + " /Backup/") #upload the current backup file to the dropboxcloud
time.sleep(30)
#Delete zip file on raspberry
os.remove(a)open crontab by typing crontab -e in your terminal
insert the file path to your python script. You can adjust the upload-frequency by changing the crontab syntax (cf. https://crontab.guru/between-certain-hours)
25 17 * * 1 /usr/bin/python3 /home/pi/Dokumente/Programme/Backup/20_12_31_Backup.pyThis will upload all data from the desired folder every Monday at 5:25 pm
after uploading your backup you can have access on all your connected devices.
