Code files
|| ● The files used in this tutorial are provided in the '''Code'''

'''files''' link.

● Please download and extract the files.

● Make a copy and then use them while practicing.
|-
|| '''Show the folder Sample'''
|| I have created a folder '''Sample '''which contains some files for demonstration.
|-
|| '''Point to the file in Downloads folder'''

<div style="color:#ff0000;"></div>
|| '''file_backup.py '''contains the code for the backup and compression of directories

'''run_backup.py''' is used to call the functions defined in '''file_backup.py'''

Ensure that both the source codes are saved in the same location.

'''Schedule.txt''' contains the commands required to schedule the backup process everyday
|-
|| '''Open file_backup.py file'''
|| Now, let us go through the '''file_backup.py''' file in the text editor.
|-
|| '''Highlight:'''
|| Import the necessary modules for File backup and compression
|-
|| '''Highlight:'''
|| First, we define a function that performs the backup operation.

We pass the source and backup directories and compression format as parameters.
|-
|| '''Highlight:'''

compress=False
|| compress is a boolean value that determines if the backup needs to be compressed.
|-
|| '''Highlight:'''

if not os.path.exists(backup_dir):
|| First we check if the backup directory exists using the '''exists '''function.
|-
|| '''Highlight:'''

os.makedirs(backup_dir)
|| We create a backup directory using the '''makedirs '''function.
|-
|| '''Highlight:'''
|| Then we check if there is an existing backup directory named '''current_backup'''.

This existing '''current_backup''' directory is removed using '''rmtree''' function.

This prevents multiple copies of the backup directory from being created.
|-
|| '''Highlight:'''
|| We create a path for the new backup directory as '''current_backup '''using the '''join '''function.
|-
|| '''Highlight:'''

for root, dirs, files in os.walk(source_dir):
|| Next, we use the '''walk '''method to recursively traverse through the source directory.

We then try to recreate the same directory structure in the backup folder.
|-
|| '''Highlight:'''

root
|| Here, '''root '''is the current directory being traversed.
|-
|| '''Highlight:'''

relative_path = os.path.relpath(root, source_dir)
|| '''relpath '''function computes the relative path of the '''root '''to the source folder.

This helps in maintaining the same structure as the source directory.
|-
|| '''Highlight:'''
|| Then the '''join '''function is used to construct the path for the destination directory.
|-
|| '''Highlight:'''

if not os.path.exists(dest_dir):

os.makedirs(dest_dir)
|| We now check if the destination directory exists.

If it does not, then the destination directory is created.
|-
|| '''Highlight:'''
|| This for loop constructs the path to the source file in the source directory.

It will also do the same for the destination files in the backup directory.
|-
|| '''Highlight:'''

if not os.path.exists(dest_file)
|| First we check if the source file already exists in the backup directory.

If it does not exist, then the file is copied.
|-
|| '''Highlight:'''
|| Next''', getmtime''' function checks if the file has been modified since the last backup date.

The file gets copied only if it is modified.

This helps to minimize the processing when we perform backup everyday.
|-
|| '''Highlight:'''

shutil.copy2(source_file, dest_file)
|| '''copy2 '''function is used to create a copy of the source to the destination directory.
|-
|| '''Highlight:'''
|| If compress is set to '''True''', we generate a compressed backup.
|-
|| '''Highlight:'''
|| We call the '''compress_backup '''function to compress '''current_backup '''folder.
|-
|| '''Highlight:'''

shutil.rmtree(current_backup_dir)
|| After compression we use '''rmtree '''method''' '''to remove the '''current_backup '''directory.
|-
|| '''Highlight:'''
|| Finally, we print a success message indicating where the backup is stored.
|-
|| '''Highlight:'''
|| Next, we define a function to compress the backup folder
|-
|| '''Highlight:'''
|| In the function, we check which compression format has been passed.

If the format is '''zip''', we use '''make_archive '''method to create a '''zip '''archive.
|-
|| '''Highlight:'''
|| If the format is '''tar dot gz''' or '''tar dot bz2''', we use '''tarfile dot open''' function.
|-
||
|| This function creates '''tar '''archives with '''gzip '''or '''bzip2 '''compression.
|-
||
|| This method adds the contents of the source directory to the '''tar '''archive.
|-
|| '''Highlight:'''

os.path.basename(source_dir)
|| '''os dot path dot basename''' allows you to set the name of the '''tar '''archive.
|-
|| '''Highlight:'''
|| If an unsupported compression format is provided, we raise a '''ValueError'''.
|-
|| '''Save file_backup.py'''
|| Save the code as '''file_backup.py''' in the '''Downloads '''folder.
|-
|| '''Open file:'''

run_backup.py
|| Open '''Downloads '''folder and open the '''run_backup.py''' file.

Now, let us go through this code.
|-
|| '''Highlight:'''

import file_backup.py
|| We need to import the '''file_backup '''python code as a module into the '''run_backup '''file.
|-
||
* <div style="margin-left:0.635cm;margin-right:0cm;">'''In Downloads point to '''sample''' Files'''</div>

|| Go to the '''Downloads '''folder.

This is our sample directory that we will use for testing.
|-
|| '''Highlight:'''

source_directory = ‘’

backup_directory_path = ‘’

|| '''Source_directory''' shows the path of the sample folder where it is saved

'''Backup_directory_path''' shows the path where back up has to be saved.

Please change the path according to the location of your directory.

|-
|| '''Highlight:'''
|| Finally, we call the '''perform_backup '''function and pass all the parameters.
|-
|| '''Set compress=False'''
|| Let us set the '''compress '''parameter to '''False '''and the format to''' zip.'''
|-
|| '''Running the code:'''
Press Ctrl + Alt + T
|| Save the code file '''run_backup.py'''

|-
||
|| Open the '''terminal''' by pressing '''Control, Alt and T '''keys simultaneously.
|-
|| '''Type in terminal:'''

source Automation/bin/activate
|| We will open the '''virtual environment''' we created for the '''Automation '''series.

Type '''source space Automation forward slash bin forward slash activate'''.

Then press '''enter'''.
|-
|| '''Type in terminal:'''

> cd Downloads

> python3 run_backup.py

'''Highlight:'''
|| In the terminal, type '''cd Downloads '''and press enter'''.'''

Next type '''python3 run_backup.py''' and press enter.

We see a message that backup is done successfully and it is stored in this location.

Let us see the output in this directory.
|-
|| '''Switch to Downloads folder'''

'''Open current_backup'''
|| Go to the '''Downloads '''folder, and we can see a directory named '''current_backup'''.

Open the '''current_backup '''directory and you will find all the files from our source directory.

So we have successfully completed the file backup.
|-
||
|| Next we will check the working of file compression.
|-
|| <div style="margin-left:0cm;margin-right:0cm;"></div>
|| Go to '''Downloads''' folder and in the '''Sample''' directory you will see a document named '''Doc3.odt'''

Let us modify this file to see he file compression is working properly.

Open the''' Doc3.odt''' and add some images or text.

Save the file.
|-
||
* <div style="margin-left:0.635cm;margin-right:0cm;">'''In Downloads'''</div>
* <div style="margin-left:0.635cm;margin-right:0cm;">'''Right click on Sample, select properties'''</div>
* <div style="margin-left:0.635cm;margin-right:0cm;">'''Highlight size'''</div>

|| Go to '''Downloads''', right click on the Sample''' '''directory and select '''properties'''.

Here we can see the size of this directory.

After compression this size should reduce.
|-
|| '''In run_backup.py type:'''

compress=True

'''Save run_backup.py'''
|| Go to '''run_backup.py''' file and set '''compress '''to '''True'''.

This will compress the backup directory.

Save the file.
|-
|| '''In terminal type:'''

python3 run_backup.py
|| Switch to the terminal and type '''python3 run_backup.py''' again and press '''Enter'''.

We see a message that indicates successful backup and compression.
|-
||
* <div style="margin-left:0.476cm;margin-right:0cm;">'''Point to current_backup.zip'''</div>
* <div style="margin-left:0.476cm;margin-right:0cm;">'''Right click on current_backup.zip and select properties'''</div>
* <div style="margin-left:0.476cm;margin-right:0cm;">'''Highlight size'''</div>

|| This time the '''current_backup '''directory is compressed in '''zip '''format.

Again right click on the compressed '''current_backup.zip '''and select '''properties'''.

We can see that the size of the compressed folder is lesser than '''Sample '''folder.
|-
||
* <div style="margin-left:0.635cm;margin-right:0cm;">'''Open current_backup'''</div>
* <div style="margin-left:0.635cm;margin-right:0cm;"></div>

|| This is how the '''Python '''backup and compression code works.
|-
|| '''Switch to terminal'''
|| Switch back to the terminal.

Next we will learn how to schedule this program to run automatically at a specified time.
|-
|| '''Type '''crontab -e
|| We will use '''Crontab editor '''which is a '''Linux '''scheduler that runs a list of commands.

To open and edit the '''crontab editor''', in the '''terminal''', type '''EDITOR=nano space crontab space hyphen e.'''

We will type our commands here.
|-
|| '''Open schedule.txt'''

'''Copy commands from schedule.txt and paste in crontab'''
|| Go to the '''Downloads '''folder and open '''schedule.txt'''

This file contains the necessary commands required to run a scheduler.

Copy these commands.

Switch back to the terminal and paste the commands at the end of the '''crontab '''editor.
|-
|| '''Type:'''

50 11 * * *
|| Here this number<span style="color:#ff0000;">''' '''</span>represents the '''minutes''', and this<span style="color:#ff0000;">''' '''</span>is the '''hours'''.

I will set this to '''11:30''' because that is when I want the backup to be scheduled.
|-
|| '''Highlight:'''

<nowiki>* * *</nowiki>
|| This indicates that the backup will be scheduled every day at the specified time
|-
|| '''Highlight'''

/usr/bin/python3
|| This is the path to the '''python3 '''interpreter.
|-
|| '''Highlight'''

/home/jasmine/Downloads/run_backup.py
|| Next,we add the path to the '''run_backup.py''' file.
|-
|| '''Highlight'''

>> /home/jasmine/Downloads/bkp_logfile.log
|| We can print the output of our code into a '''logfile''' and save it in the '''Downloads '''folder

Please change the path according to your system.
|-
|| '''Highlight'''

2>&1

'''Save crontab:'''
Ctrl+X
Y
Enter
|| This redirects all standard errors to the standard output file.

Now, press '''Ctrl '''plus '''X '''and then press '''Y''' followed by '''Enter '''to save and exit.

Now we have scheduled the r'''un_backup.py''' file to be executed at '''11:30''' everyday.
|-
||
|| <div style="color:#000000;">The current date and time as of the creation of this video is '''28th September 11:38'''</div>

<div style="color:#000000;">We will check if the scheduler has completed the backup the next day.</div>
|-
||
|| Now the date is '''29th September 11:35 a.m.'''
|-
|| '''Open current_backup'''

'''Directory'''

'''Point to Doc4.txt'''
|| <div style="color:#000000;">Let us go to the downloads folder, extract the '''current_backup''' directory and open it.</div>

<div style="color:#000000;">We can see that all the files have been backed up.</div>
|-
|| '''Narration'''
|| We can also check if there were any output messages or errors after the backup.
|-
|| '''Point to bkp_logfile.log'''

'''Open bkp_logfile.log'''
'''Highlight output in'''
'''bkp_logfile.log'''
|| In the '''Downloads '''folder, we see that a '''bkp_logfile.log''' has been created.

Here, the output or error messages of the program will be stored after the '''cron job''' is completed.
|-
|| '''Narration'''
|| In this way, we can backup and compress a directory at a predetermined time and date.
|-
|| '''Type in terminal:'''

deactivate
|| In the terminal, type '''deactivate'''.This will allow you to exit the virtual environment.
