Backup Files Using Python

Backup Files using Python is an essential practice to ensure you don’t lose important data due to unexpected events like hardware failures or accidental deletions. Using Python, you can automate this process easily and efficiently. With just a simple script, you can regularly copy your important files from one location to another, making sure you always have a safe copy:

Step 1: Install Required Libraries

First, ensure you have the necessary libraries. You might need to install the following:

pip install smtplib email

Step 2: Install Schedule library

Ensure you have the schedule library installed. You can install it using pip:

Styled Text Area
pip install schedule

Step 3: Script To Automate Backup

Styled Text Area
import os
import shutil
import schedule
import time

def backup_files(source_dir, backup_dir):
if not os.path.exists(backup_dir):
os.makedirs(backup_dir)
for filename in os.listdir(source_dir):
source_file = os.path.join(source_dir, filename)
backup_file = os.path.join(backup_dir, filename)
shutil.copy(source_file, backup_file)
print(f'Backed up: {source_file} to {backup_file}')

def scheduled_backup():
source_directory = "/path/to/source/directory" # Change to your source directory
backup_directory = "/path/to/backup/directory" # Change to your backup directory
backup_files(source_directory, backup_directory)

# Schedule the backup job to run every day at a specific time
schedule.every().day.at("02:00").do(scheduled_backup) # Change to your desired time

while True:
schedule.run_pending()
time.sleep(1)

Step 4: Update Directory Path

Edit the script to set your source and backup directories:
source_directory = “/path/to/source/directory”
backup_directory = “/path/to/backup/directory”

Step 5: Set the Backup Time

Change the time in the schedule.every().day.at("02:00").do(scheduled_backup) line to your desired backup time. The time should be in 24-hour format.

Step 6: Save the Backup File

Save the script as backup_script.py.

Step 7: Run the Script

Run the script using Python. Open a terminal or command prompt and navigate to the directory where you saved backup_script.py. Then run:

python backup_script.py
