How to write the code of the python10.4 backup script? for this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

The code of version 4 is quite long, so many people feel helpless about it, but you have a better understanding of it through the following code, here is a detailed description of the relevant content. I hope you get something.

#! / usr/bin/python

# Filename: backup_ver4.py

Import os

Import time

# 1. The files and directories to be backed up are

Specified in a list.

Source = ['/ home/swaroop/byte','/ home/swaroop/bin']

# If you are using Windows, use source =

[ritual C:\ Documents'

, ringing D:\ Work'] or something like that

# 2. The backup must be stored in a main backup

Directory

Target_dir ='/ mnt/e/backup/' # Remember to change

This to what you will be using

# 3. The files are backed up into a zip file.

# 4. The current day is the name of the

Subdirectory in the main directory

Today = target_dir + time.strftime ('% Y% m% d')

# The current time is the name of the zip archive

Now = time.strftime ('% H% M% S')

# Take a comment from the user to create the name

Of the zip file

Comment = raw_input ('Enter a comment->')

If len (comment) = = 0: # check if a comment was entered

Target = today + os.sep + now + '.zip'

Else:

Target = today + os.sep + now +'_'+\

Comment.replace (','_') + '.zip'

# Notice the backslash!

# Create the subdirectory if it isn't already there

If not os.path.exists (today):

Os.mkdir (today) # make directory

Print 'Successfully created directory', today

# 5. We use the zip command (in Unix/Linux) to put the

Files in a zip archive

Zip_command = "zip-qr'% s"% (target,'

'.join (source))

# Run the backup

If os.system (zip_command) = = 0:

Print 'Successful backup to', target

Else:

Print 'Backup FAILED'

The article mentioned, "I also hope that one of the optimizations is to use the tar command instead of the zip command. One advantage of this is that backups are faster and smaller when you use the tar and gzip commands together. If you want to use these archives in Windows, WinZip can also easily handle these .tar.gz files. The tar command is available by default on most Linux/Unix systems. Windows users can also download and install it. The command string will now be:

Tar = 'tar-cvzf% s% s-X / home/swaroop/

Excludes.txt'% (target,''.join (srcdir))

What needs to be added is that Windows users install LibArchive after the command is bsdtar, and if you want to use the-z option, you also need to install gzip software. In the code

Target = today + os.sep + now + '.zip'

Change to

Target = today + os.sep + now + '.tar.gz'

Use

Bsdtar-cvzf% s% s-X / home/swaroop/

Excludes.txt'% (target,''.join (source))
